         IIJ to List on the Mothers Market of the Tokyo Stock Exchange


    TOKYO--(BUSINESS WIRE)--Nov. 9, 2005--Internet Initiative Japan
Inc. ("IIJ", NASDAQ: IIJI), one of Japan's leading Internet access and
comprehensive network solutions providers, today announced that it
received notification that the Tokyo Stock Exchange has approved the
listing of its shares of common stock on the Mothers market of the
Tokyo Stock Exchange. Pricing is expected to occur on a date between
November 24 and November 28, 2005. The expected listing date is
December 2, 2005.
    In connection with the Mothers listing, IIJ plans to issue 12,500
new shares (equivalent to 5,000,000 American Depository Receipts
("ADRs")) and two shareholders, NIF SMBC Ventures Co., Ltd. and JAFCO
Co., Ltd., which are Japanese venture capital firms, plan to sell
7,500 existing shares in an underwritten public offering in Japan. In
addition, the lead underwriter will be provided by the selling
shareholders with the option to purchase up to 3,000 additional shares
to cover over-allotments, if any. The newly issued shares will
comprise approximately 6.1% of IIJ's total shares after giving effect
to the issuance. IIJ plans to use the proceeds from the issuance of
the new shares for ongoing capital investment in operations and
research and development.
    The offer price for the public offering in Japan will be based on
the average of the closing price of ADRs on the NASDAQ National market
for five days prior to the pricing date subject to a discount
determined in accordance with market demand under the Japanese market
practice. In the case the average is higher than the closing price on
the date prior to the pricing date, the closing price on the date
prior to the pricing date will be used for calculation of the price.
    IIJ has been advised by the prospective lead underwriter for the
offering that the underwriters may conduct stabilizing and other
activities in connection with the offering, in accordance with
applicable laws. The closing of the offering requires the satisfaction
of various conditions, including fulfilling the listing requirements
of the Mothers market of the Tokyo Stock Exchange.

    Any shares sold in connection with the proposed offering have not
been and will not be registered under the U.S. Securities Exchange Act
of 1933, as amended (the "Securities Act") and may not be offered or
sold in the United States absent registration under the Securities Act
or an applicable exemption from the registration requirements of the
Securities Act.
    Statements made in this press release regarding IIJ's or
management's intentions, beliefs, expectations, or predictions for the
future are forward-looking statements that are based on IIJ's and
managements' current expectations, assumptions, estimates and
projections about its business and the industry. These forward-looking
statements are subject to various risks, uncertainties and other
factors that could cause IIJ's actual results to differ materially
from those contained in any forward-looking statement.

          day before the pricing date (when there is no closing price, the
          nearest day with a closing price) is below the average price above,

1. American Depository Receipts
(1) American Depository Receipts being traded on the U.S. NASDAQ National Market

by 400, the stock-ADR conversion ratio and an exchange rate) will fluctuate
along with the fluctuation of the market price of the Company's ADRs and the
dollar-yen exchange rate even in the period after determination of the offer
price for the public offering of new shares, secondary offering of shares sold
through underwriting by the underwriter and the secondary offering of shares
sold through over-allotment ("the public and secondary offering") until the date
of commencement of the Company's shares to be traded on the Mothers market of
the Tokyo Stock Exchange.

The closing of the offering requires the satisfaction of various conditions,
including fulfilling the listing requirements of the Mothers market of the Tokyo
Stock Exchange.

The offer price for the public and secondary  offering will be determined on the
pricing date, in accordance  with the method  prescribed in Article 7-2 of No.14
Rules of Fair Practice of the Japan Securities Dealers Association, based on the
follows and in consideration of demand conditions.

(The base for determination of offer price)
The  average  of the  closing  price of the  Company's  ADRs on the U.S.  NASDAQ
National Market (less than one cent is omitted) for the five trading days before
the pricing date (days without a closing price are not included),  multiplied by
400 (the stock-ADR  conversion  ratio) and the  dollar-yen  exchange rate of the
Bank of Tokyo Mitsubishi's telegraphic transfer middle rate on the pricing date,
and multiplied by a rate between 0.90 to 1.00 (less than one yen is omitted). In
the event that the closing price on the previous day of pricing date (when there
is no closing  price,  the nearest day with closing  price) is below the average
price  above,  the  closing  price on the  previous  day (or the  nearest  day),
calculated as above and multiplied by a rate between 0.90 to 1.00 (less than one
yen to be omitted) and determined in consideration of demand conditions.

4. Secondary offering of shares sold through over-allotment

For the secondary  offering of shares sold through  over-allotment  described in
"3. Secondary offering (of shares sold through  over-allotment)" above, the lead
underwriter   may   conduct  a  secondary   offering  of  shares  sold   through
over-allotment  up to a maximum  of 3,000  shares  that it plans to borrow  from
Company shareholders,  after taking into consideration the demand conditions for
the public  offering  of new shares  described  in "1.  Public  offering  of new
shares" and the secondary  offering of shares sold through  underwriting  by the
underwriter  described  in  "2.  Secondary  offering  (of  shares  sold  through
underwriting  by the  underwriter)"  above.  Though  the  number of shares  sold
through  over-allotment is planned to be 3,000, the number is the maximum and it
may decrease,  or the secondary  offering of shares sold through  over-allotment
itself may not be conducted at all.

In the case that the secondary offering of shares sold through over-allotment is
conducted,  the lead underwriter will be granted an option to acquire additional
shares of the  Company's  common  stock up to the number of shares sold  through
over-allotment   ("green-shoe  option"),  from  Company  shareholders  with  the
exercise period from Friday,  December 2, 2005 through  Wednesday,  December 28,
2005.  The lead  underwriter  may also purchase  shares of the Company's  common
stock on the  Mothers  market of the Tokyo  Stock  Exchange  up to the number of
shares sold through  over-allotment (the "syndicate cover transactions") for the
purpose of returning the shares that it borrowed  from the Company  shareholders
(the "borrowed shares") from Friday, December 2, 2005 to Thursday,  December 22,
2005 (the "syndicate cover transaction period"), and all of the shares purchased
by the syndicate  cover  transactions  will be used for the lead  underwriter to
return the borrowed shares to the Company  shareholders.  In the syndicate cover
transaction  period,  the  lead  underwriter  may not  conduct  syndicate  cover
transactions at all on its decision,  or finish the syndicate cover transactions
before purchasing the number of shares sold through over-allotment.

IIJ has been advised by the prospective  lead  underwriter for the offering that
the underwriters may conduct stabilizing and other activities in connection with
the  offering,   in  accordance   with  applicable  laws  as  described  in  "2.
Stabilization  transactions in the United States",  and may convert ADRs that it
purchased by the stabilization  transactions into the Company's shares of common
stock and use all or a portion of the  converted  shares to return the  borrowed
shares.

The remaining shares of the borrowed shares that the lead underwriter  purchased
by the syndicate cover  transactions and  stabilization  transactions  above and
return, will be returned to the lead underwriter by green-shoe option.

5. United States Securities Act of 1933, as amended

Any shares sold in connection with the proposed  offering have not been and will
not be  registered  to the United  States  Securities  and  Exchange  Commission
("SEC")  under  the  United  States  Securities  Act of 1933,  as  amended  (the
"Securities  Act"),  and may not be  offered  or sold in the  United  States  as
defined in SEC Rule 902 (l) under the Securities Act to U.S.  persons as defined
in SEC Rule 902 (k) or for the  account or benefit of a U.S.  person  (excluding
distributors)  (collectively,  "U.S.  persons")  absent  registration  under the
Securities Act or an applicable exemption from the registration  requirements of
the Securities Act.

The underwriters (including Nomura Securities Co., Ltd., as the underwriter of
secondary offering of shares sold through over-allotment. The same in 5. United
States Securities Act of 1933, as amended) have agreed not to offer or sell the
shares sold in connection with the proposed offering in the United States or to
any U.S. persons in relation to the shares sold in the connection with the
proposed offering through 40 days after the listing of shares offered in the
proposed listing (Tuesday, January 10, 2005) or, for any remaining shares, until
the sale of such shares is completed, and prior to the expiration of this
period, to send a confirmation or other notice to any underwriter, dealer, or
other person who participates, pursuant to a contractual arrangement, in the
proposed offering, stating that the purchaser is subject to the same
restrictions on offers and sales that apply to distributors.

9. Distribution of profits to shareholders

     (1) Basic policy on the distribution of profits

          The Company has not paid dividends in the past years. The Company
          considers the payment of dividends to shareholders to be an important
          management issue. However, at the current time, the Company's policy
          is to give priority to securing funds to strengthen its financial
          position and to use funds for operational development. Therefore,
          there is a possibility that the Company will not pay dividends in the
          near future.

     (2) Actual results of payment of dividends in the last three fiscal years

          Though the Company made a 1 to 5 stock split with a payable date of
          October 11, 2005, the basic and diluted net income (loss) per share
          above is shown as net income loss that the split is not reflected to.

10. Information on dilution by the potential common shares
    The Company granted its directors and employees stock options to acquire
    new shares in April 2000 and June 2001 based on Clause 2, Article 280-19 of
    the pre-revised Commercial Code of Japan. The number of shares in issuance
    was 191,800 and the total number of the potential common shares was 2,700,
    1.4% of the number of shares in issuance as of October 2005.

Notes:

1.  Basic and diluted net income per share in the consolidated
    financial results for the fiscal year ended March 31, 2005 and the
    interim period ended September 30, 2005 (under U.S. GAAP) are
    computed using the weighted-average number of shares of common
    stock outstanding during the fiscal year or period. Basic and
    diluted net income per share in the non-consolidated financial
    results for the fiscal year ended March 31, 2005 and the interim
    period ended September 30, 2005 (under Japanese GAAP) are computed
    using the weighted-avarage number of shares of common stock in
    issuance during the fiscal year or period.

2. Consolidated (under U.S. GAAP) and non-consolidated (under Japanese
    GAAP) basic and diluted net income per share for the fiscal year
    ending March 31, 2006 is calculated assuming that 204,300 shares
    are issued as of period end, after the 1 to 5 stock spilt that IIJ
    made with the payable date of October 11, 2005 and including the
    12,500 shares proposed to be issued in connection with the
    contemplated listing.

3.  For reference, the figures per share when the stock split on
    October 11, 2005 is reflected are the following:

[Qualitative explanations regarding the consolidated operating results]

(1) Overview

   In the first  quarter of FY2005,  Japan's  economy  showed  signs of a gentle
recovery,  such as improved  corporate  earnings and increased  private  capital
spending, though there were uncertain factors such as long-term rising crude oil
prices.
   In  this  environment,   utilization  of  Internet-related   technologies  in
corporate internal networks and business systems has been proceeding, traffic in
business has been increasing and networks are becoming  increasingly complex for
our primary customer segment,  large-sized corporation and public organizations.
Our group continued to meet the outsourcing needs of these customers and provide
them with reliable total network solutions.
   In the consolidated  operating results for the first quarter of FY2005 of our
group,  total revenues amounted to JPY 9,880 million,  operating income amounted
to JPY 247 million, income before income tax expense amounted to JPY 682 million
and net income amounted to JPY 623 million.
   Operating results by service were as follows:

1)       Internet connectivity and value-added services

   For dedicated access services,  while corporate  customers  shifted to higher
bandwidth  and the number of contracts  for broadband  services  increased  with
expansion of multi-site connectivity projects, revenues decreased due to network
reorganization of some of our large customers and amounted to JPY 2,747 million.
  For dial-up access services,  revenues from the services for retail customers,
such as IIJ4U were in the declining trend and amounted to JPY 699 million.
   For value-added services,  with growing corporate outsourcing needs, revenues
amounted to JPY 1,388 million due to growing  revenues from data center  related
services,  server  outsourcing  services  such as e-mail  servers,  and  network
outsourcing services such as SEIL, SMF used for multi-site connectivity projects
and others.
   For other  services,  revenues  amounted to JPY 933 million,  due to steadily
growing sales of Wide-area Ethernet Services.
  As a result of the above,  revenues from Internet connectivity and value-added
services in the first quarter of FY2005 amounted to JPY 5,767 million. Due to an
increase in revenues from higher-margin  value-added services and suppression of
fixed cost of revenues (mainly  backbone costs),  the gross margin from Internet
connectivity and value-added services amounted to JPY 803 million, and the gross
margin ratio was 13.9%.

2) Systems Integration

   In the first quarter of FY2005, revenues from systems integration amounted to
JPY 3,840 million, including revenues related to outsourced operations which are
expected to be incoming on a ongoing basis, amounted to JPY 2,647 million.


                                      -2-


  The gross margin from systems integration amounted to JPY 930 million, and the
gross  margin  ratio was 24.2%,  due to increased  revenues  from  higher-margin
outsourced operations.

3) Equipment sales

  Revenues from equipment  sales in the first quarter of FY2005  amounted to JPY
273 million.  The gross margin amounted to JPY 30 million,  and the gross margin
ratio was 10.9%.

(Notes)
          1. We made a 1 to 5 stock split with a payable date of October 11,
          2005. As a result, the number of shares outstanding was 191,800
          (38,360 before the stock split) on the date of release of this
          document. We also plan to issue 12,500 new shares in December 2005.
          For our target of consolidated net income per share for full FY2005 in
          this document, we indicate the figure calculated with the estimated
          number of shares outstanding of 204,300.

          2. Statements made in this press documents regarding IIJ's or
          management's intentions, beliefs, expectations, or predictions for the
          future are forward-looking statements that are based on IIJ's and
          managements' current expectations, assumptions, estimates and
          projections about its business and the industry. These forward-looking
          statements, such as statements regarding FY2005 revenues and operating
          and net profitability, are subject to various risks, uncertainties and
          other factors that could cause IIJ's actual results to differ
          materially from those contained in any forward-looking statement.
          These risks, uncertainties and other factors include: IIJ's ability to
          maintain and increase revenues from higher margin services such as
          system integration and value-added services; the possibility that
          revenues from connectivity services may decline substantially as a
          result of competition and other factors; the ability to compete in a
          rapidly evolving and competitive marketplace; the impact on IIJ's
          profits of fluctuations in costs such as backbone costs and
          subcontractor costs; the impact on IIJ's profits of fluctuations in
          the price of available-for-sale securities; the impact of
          technological changes in its industry; IIJ's ability to raise
          additional capital to cover its indebtedness; the possibility that
          NTT, IIJ's largest shareholder, may decide to exercise substantial
          influence over IIJ; and other risks referred to from time to time in
          IIJ's filings on Form 20-F of its annual report and other filings with
          the United States Securities and Exchange Commission.

[Qualitative explanations regarding outlook of financial results]

Basis of Presenting Consolidated Financial Statements for the First Quarter of
FY2004

1.   The Terminology, Form, and Preparation Methods for Consolidated Financial
     Statements for the First Quarter of FY2005

   The financial statements for the first quarter of FY2005 have been prepared
in accordance with the provisions of article 81 "provisions for the terminology,
form, and preparation methods for interim consolidated financial statements"
(Ministry of Finance, ordinance No. 24, 1999), and based on the accounting
treatment principles and procedures and disclosure methods required in relation
to the issuance of American Depository Receipts ("ADRs") (U.S. GAAP including
Accounting Research Bulletins ("ARB"), Accounting Principles Board ("APB")
Opinions, Statement of Financial Accounting Standards ("SFAS") and related
interpretation guidelines).
   IIJ registered  the sale of ADRs with the Securities and Exchange  Commission
("SEC") of the United States of America under the Securities and Exchange Act of
1933, as amended and registered the quotation of the ADRs on the NASDAQ National
Market of the United  States of America in August 1999.  Further,  in accordance
with  Rule 13 of the U.S.  Securities  Exchange  Act of 1934,  as  amended,  IIJ
regularly  files  with the SEC an  annual  report on Form  20-F  which  includes
consolidated financial statements prepared in accordance with U.S. GAAP.

2.   Main Differences from Preparation in Accordance with Provisions and
     Principles for Interim Consolidated Financial Statements

   The main differences between consolidated  financial statements for the first
quarter of FY2005 prepared in accordance with U.S accounting standards and those
prepared in  accordance  with  Japan's  provisions  and  principles  for interim
consolidated  financial statements and the effect by important monetary items on
income from operations before income tax expense,  minority interests and equity
in net  income of equity  method  investees  in the first  quarter of FY2005 are
given below.

(1)  Differences Regarding the Composition of Quarterly Consolidated Financial
     Statements
   Quarterly consolidated financial statements have been prepared based on
U.S. GAAP comprise quarterly consolidated balance sheets, quarterly consolidated
statements of operations, quarterly consolidated statements of shareholders'
equity, quarterly consolidated statements of cash flows, and notes to quarterly
consolidated financial statements.

(2)  Differences Regarding Disclosure in Quarterly Consolidated Financial
     Statements

   In quarterly consolidated statements of operations, equity in net income of
equity method investees is shown as a separate item after income from operations
before income tax expense.

(3)  Differences Regarding Accounting Treatment Standards

   1) Income taxes
   Income taxes are accounted for in accordance with SFAS No. 109. Changes in
the deferred income tax asset valuation allowance that relate to the tax effect
of unrealized gains and losses on available-for-sale securities have been
recorded as a separate component of other comprehensive income.

   2) Accounting treatment of lease transactions
   The Company accounts for significant lease transaction agreements that
fulfill the requirements for capitalized leases as stipulated by SFAS No. 13, in
accordance with SFAS. As a result, finance lease transactions, other than those
that recognize transfer of ownership to the lessee, are treated as purchases. In
the first quarter of FY2005, this accounting treatment of lease transactions
resulted in a JPY 305 thousand reduction in income from operations before income
tax expense.

   3) Stock issuance cost
     Stock issuance cost is accounted for as expenses related to capital
transactions and deducted from additional paid-in capital. In the first quarter
of FY2005, this accounting treatment resulted in a JPY 9,480 thousand increase
in income from operations before income tax expense.

   4) Retirement benefit accounting
     Unfunded retirement benefits and noncontributory defined benefit pension
plans are accounted for in accordance with SFAS No. 87. In the first quarter of
FY2005, this accounting treatment resulted in a JPY5,215 thousand reduction in
income from operations before income tax expense.

   5) Comprehensive income
     Comprehensive income is accounted for in accordance with SFAS No. 130
"reporting comprehensive income." SFAS requires additional disclosure of
information in consolidated financial statements. In the first quarter of
FY2005, this accounting treatment did not result in any change in income from
operations before income tax expense.

Notes to Quarterly Consolidated Financial Statements for the first quarter of
FY2005

1. DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   Internet Initiative Japan Inc. ("IIJ"), a Japanese  corporation,  was founded
in December  1992 to develop  and operate  Internet  access  services  and other
Internet-related services in Japan and is 31.6 percent owned by Nippon Telegraph
and Telephone Corporation ("NTT") and its subsidiary,  NTT Communications,  Inc.
as of June  30,  2005.  IIJ and  consolidated  subsidiaries  (collectively,  the
"Company")  provide Internet access services  throughout  Japan, into the United
States of  America  and into the rest of Asia,  and  value-added  services.  The
Company also provides systems integration,  which mainly comprise  consultation,
design,    development,    construction,    operation   and    maintenance   for
Internet-related  systems;  equipment sales in relation to equipment procurement

Internet-related  services  industry  segment  including  revenues  from systems
integration. Substantially all revenues are from customers operating in Japan.
   The accompanying  quarterly  consolidated  financial statements for the first
quarter  of  FY2005  have  been  prepared  on  a  going-concern   basis,   which
contemplates  the  realization of assets and the  satisfaction of liabilities in
the normal course of business. Although the Company recorded operating income in
the first quarter of FY2005,  the Company has incurred  operating losses and net
losses in each of the past six  fiscal  years  ended  March 31,  2004,  with the
exception of operating income for FY2001.
   At June 30, 2005, the Company had  indebtedness  of JPY 16,980,270  thousand.
For the first quarter of FY2005 and full FY2004,  the Company recorded operating
income of JPY 1,247,651  thousand and JPY 246,678 thousand and net income of JPY
2,906,269 thousand and JPY 622,674 thousand, respectively.  Although the Company
had negative working capital of JPY 4,453,793  thousand as of June 30, 2005, the
management  considered various  alternatives to increase working capital such as
increasing   operating   income  and  liquidating   certain   available-for-sale
securities of JPY 6,920,858 thousand as of June 30, 2005.

Certain Significant Risks and Uncertainties

   The Company has  available-for-sale  securities of JPY 6,920,858  thousand at
June  30,  2005,  and  believes  that  the   fluctuations   in  stock  price  of
available-for-sale  securities  could  have a  material  adverse  effect  on the
Company's future financial position, results of operations or cash flows.
   The Company relies on  telecommunications  carriers for a significant portion
of network backbone, and Nippon Telegraph and Telephone East Corporation, Nippon
Telegraph and Telephone West  Corporation,  electric  power  companies and their
affiliates for local connections to customers. The Company believes that its use
of multiple  carriers and suppliers  significantly  mitigates  concentrations of
credit risk. However, any disruption of telecommunication services could have an
adverse effect on operating results.
   Financial  instruments that potentially subject the Company to concentrations
of credit risk consist principally of cash investments,  accounts receivable and
guarantee deposits.  The Company's management believes that the risks associated
with  accounts  receivable  is  mitigated  by  the  large  number  of  customers
comprising its customer base.

Summary of Significant Accounting Policies

Basis of Presentation

   IIJ maintains its record in accordance with generally accepted accounting
principles in Japan. Certain adjustment and reclassifications have been
incorporated in the accompanying consolidated financial statements to conform to
U.S. GAAP. These adjustments were not recorded in the statutory accounts.

Consolidation

   The consolidated financial statements for the first quarter of FY2005 include
the accounts of IIJ and all of its  subsidiaries,  Net Care,  Inc. ("Net Care"),
IIJ-Tech,  IIJ-MC, IIJ Financial Systems, Inc. ("IIJ-FS"), and IIJ America, Inc.
("IIJ  America"),  which  have first  quarters  ending  June 30,  except for IIJ
America.  IIJ America's first quarter end is March 31 and such date was used for
purposes  of  preparing  the  consolidated  financial  statements  as it is  not
practicable  for the  subsidiary to report its financial  results as of June 30.
There were no significant  events that occurred  during the  intervening  period
that would require adjustment to or disclosure in the accompanying  consolidated
financial statements.  Significant  intercompany  transactions and balances have
been  eliminated in  consolidation.  Investments in companies over which IIJ has
significant  influence but not control are  accounted for by the equity  method.
For other than a temporary  decline in the value of investments in equity method
investees below the carrying amount, the investment is reduced to fair value and
an impairment loss is recognized.

                                      -14-


   A subsidiary or equity method  investee may issue its shares to third parties
at amounts per share in excess of or less than the  Company's  average per share
carrying value. With respect to such transactions, the resulting gains or losses
arising  from the change in  ownership  are  recorded  in income for the year in
which such shares are issued.

Use of Estimates

   The preparation of financial statements in conformity with U.S. GAAP requires
management to make estimates and assumptions that affect the reported amounts of
assets and  liabilities  and disclosure of contingent  assets and liabilities at
the date of the  financial  statements  and  reported  amounts of  revenues  and
expenses during the reporting period. Significant estimates and assumptions used
are primarily in the areas of  impairment  loss on investment in and advances to
equity method investees, valuation allowances for deferred tax assets, allowance
for doubtful accounts, and estimated lives of fixed assets. Actual results could
differ from those estimates.

Revenue Recognition

   Revenues from customer connectivity services consist principally of dedicated
Internet  access  services  and  dial-up  Internet  access  services.  Dedicated
Internet access services  represent  full-line IP services and standard-level IP
services (T1 Standard and IIJ  FiberAccess/F  Service).  Dial-up Internet access
services are provided to both enterprises and individuals  (IIJ4U).  The term of
these contracts is one year for dedicated Internet access services and generally
one month for dial-up  Internet access  services.  All these services are billed
and recognized monthly on a straight-line basis.
   Value-added service revenues consist principally of sales of various Internet
access-related  services such as firewall  services.  Value-added  services also
include monthly fees from data center services such as housing,  monitoring, and
security services.  Other revenues under  connectivity and value-added  services
consist  principally  of  call-center  customer  support and Wide-area  Ethernet
services,  which offer  connectivity  services for the  construction of networks
connecting a customer's multiple  operational sites. The terms of these services
are generally for one year and revenues are recognized on a straight-line  basis
during the service period.
   Initial set up fees received in  connection  with  connectivity  services and
value-added services are deferred and recognized over the contract period.
   Systems  integration  revenues consist  principally of consultation,  design,
development,   construction  and  related  maintenance,   monitoring  and  other
operating  services of Internet network systems.  The period for the development
of the systems or designs is less than one year and revenues are recognized when
network  systems and equipment are delivered and accepted by the customer  under
the completed  contract method.  The development of the Internet network systems
or design includes multiple element  arrangements such as consultation,  systems
design,  planning,  development  and  construction  services,  and equipment and
software purchased from third parties. When the equipment or system is delivered
prior to other  elements of the  arrangement,  revenue is  deferred  until other
service  elements  are  completed  and  accepted by the  customer.  Maintenance,
monitoring,  and  operating  service  revenues are  recognized  ratably over the
separate contract period, which is generally for one year.
   Systems  integration  service is subject to the  Emerging  Issues  Task Force
("EITF") of the Financial  Accounting  Standards Board ("FASB") Issue No. 00-21,
"Revenue Arrangements with Multiple  Deliverables" which was adopted as of April
1, 2004.
   Equipment  sales  represent  revenues  earned  in which the  Company  acts as
principal in the  transaction,  takes title to the  equipment  and has risks and
rewards of ownership while in inventory and are reported gross as the indicators
outlined in the provisions of the EITF Issue No. 99-19 "Reporting  Revenue Gross
as a Principal versus Net as an Agent" are met.

Cash and Cash Equivalents

   Cash and cash  equivalents  include  time  deposits  and  readily  marketable
securities with original maturities of three months or less.

Allowance for Doubtful Accounts

   An allowance for doubtful accounts is established in amounts considered to
be appropriate based primarily upon the Company's past credit loss experience
and an evaluation of potential losses in the receivables outstanding.

Other Investments

   In accordance with Statement of Financial  Accounting  Standards ("SFAS") No.
115,  "Accounting for Certain  Investments in Debt and Equity  Securities,"  all
marketable  equity securities are classified as  available-for-sale  securities,
which are accounted for at fair value with unrealized  gains and losses excluded
from earnings and reported in accumulated other  comprehensive  income. The cost
of securities sold is determined based on average cost.

                                      -15-


   The Company  reviews the fair value of  available-for-sale  investments  on a
regular basis to determine if the fair value of any  individual  investment  has
declined  below its cost and if such  decline  is other than  temporary.  If the
decline  in value is judged to be other  than  temporary,  the cost basis of the
investment is written down to fair value. Other than temporary declines in value
are determined  taking into  consideration  the extent of decline in fair value,
the length of time that the  decline in fair value  below cost has  existed  and
events that might  accelerate  the  recognition  of  impairment.  The  resulting
realized  loss is included in the  consolidated  statements of operations in the
period in which the decline was deemed to be other than temporary.
   Non-marketable  equity  securities  are  carried at cost as fair value is not
readily  determinable.  If the value of a security is estimated to have declined
and such decline is judged to be other than  temporary,  the security is written
down  to  the  fair  value.   Determination   of  impairment  is  based  on  the
consideration of such factors as operating results, business plans and change in
the regulatory,  economic or  technological  environment of the investees.  Fair
value is determined  as the  Company's  interest in the net assets of investees.

Inventories

   Inventories  consist  mainly of network  equipment  purchased  for resale and
work-in-process  for development of Internet network systems.  Network equipment
purchased for resale is stated at the lower of cost,  which is determined by the
average-cost  method,  or market.  Work-in-process  for  development  of network
systems is stated at the lower of actual  production costs,  including  overhead
cost, or market.  Inventories are reviewed  periodically and items considered to
be  slow-moving  or obsolete are written down to their  estimated net realizable
value.

Property and Equipment

   Property and equipment are recorded at cost. Depreciation and amortization of
property and equipment, including purchased software and capitalized leases, are
computed  principally  using  the  straight-line  method  based  on  either  the
estimated useful lives of assets or the lease period,  whichever is shorter. The
useful lives for  depreciation  and  amortization  by major asset classes are as
follows:
----------------------------------------------------------------------------
                                                     Range of useful lives
----------------------------------------------------------------------------
  Data communications, office and other equipment     2 to 15 years
  Leasehold improvements                              3 to 15 years
  Purchased software                                        5 years
  Capitalized leases                                   4 to 7 years
----------------------------------------------------------------------------

Impairment of Long-Lived Assets

   Long-lived  assets consist  principally of property and equipment,  including
those items  leased  under  capital  leases.  In  accordance  with SFAS No. 144,
"Accounting  for the Impairment or Disposal of Long-Lived  Assets",  the Company
evaluates  the  impairment of long-lived  assets  whenever  events or changes in
circumstances  indicate  that  the  carrying  amount  of an  asset  may  not  be
recoverable.  There was no impairment  loss for  long-lived  assets in the first
quarter of FY2005.

Goodwill and Intangible Assets

   Under  SFAS  No.  142,  "Goodwill  and  Other  Intangible  Assets",  goodwill
(including equity-method goodwill) and intangible assets that are deemed to have
indefinite  useful  lives  are not  amortized,  but are  subject  to  impairment
testing. Impairment testing is required to be performed at adoption and annually
or more frequently if events or changes in circumstances indicate that the asset
might be  impaired.  The  Company  selected  March 31 as its  annual  impairment
testing date.

Income Taxes

   The provision  for income taxes is based on earnings  before income taxes and
includes the effects of temporary  differences  between  assets and  liabilities
recognized  for  financial  reporting  purposes  and  income  tax  purposes  and
operating loss carryforwards.  Valuation  allowances are provided against assets
that are not likely to be realized.

Foreign Currency Transactions

   Foreign currency assets and liabilities,  which consist substantially of cash
and  accounts  payable  for  connectivity   leases  to  international   carriers
denominated  in U.S.  dollars,  are  stated at the amount as  computed  by using
exchange rates at the end of the quarter and the resulting  transaction  gain or
loss is recognized in earnings.

                                      -16-


Derivative Financial Instruments

   All derivatives are recorded at fair value as either assets or liabilities in
the balance sheet in accordance  with SFAS No. 133,  "Accounting  for Derivative
Instruments  and  Hedging  Activities,"  as  amended by SFAS No. 138 and No. 149
(collectively,  "SFAS No. 133").  In  accordance  with SFAS No. 133, the Company
designated  interest swap contracts as a hedge of the  variability of cash flows
to be paid related to interest on floating rate borrowings (cash flow hedge) and
an effective portion of the derivative's gain or loss is initially reported as a
component  of other  comprehensive  income and  subsequently  reclassified  into
earnings  when the  underlying  transaction  affects  earnings.  An  ineffective
portion of the gain or loss is reported in earnings immediately.
   The Company  enters into  contracts to hedge interest rate risks and does not
enter into contracts or utilize  derivatives for trading  purposes.

Stock-Based Compensation

   The Company accounts for stock-based  compensation  using the intrinsic value
method prescribed in Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees" and related interpretations. Accordingly, the Company
recognizes  compensation  expense in an amount equal to the excess of the quoted
market  price  over the  exercise  price of the  option at the grant  date.  For
options with a vesting period, the compensation expense is charged to operations
ratably over the vesting period.  The Company has not recognized any stock-based
compensation expense for the first quarter of FY2005.

Advertising

Advertising costs are expensed as incurred.

Basic and Diluted Net Income per Share

   Basic  and   diluted   net   income   per  share  are   computed   using  the
weighted-average  number of shares of common stock outstanding  during the first
quarter of FY2005. For the first quarter of FY2005, all potential common shares,
shares  issuable  upon  exercise of stock  options,  have been excluded from the
computation  of diluted net income  because the  exercise  prices of the options
were greater than the average market price of common shares.  Diluted net income
per share does not include the effects of the following potential common shares:

--------------------------------------------------------------------------------
                                                At the end of the first quarter
                                                 of FY2005 (June 30, 2005)
--------------------------------------------------------------------------------
  Shares issuable under stock options                   540
--------------------------------------------------------------------------------

Other Comprehensive Income (Loss)

   Other  comprehensive  income  (loss)  consists  of  translation   adjustments
resulting from the translation of financial  statements of a foreign subsidiary,
unrealized gains or losses on available-for-sale  securities and gains or losses
on cash flow hedging derivative instruments.

Segment Reporting

   SFAS No.  131,  "Disclosures  about  Segments  of an  Enterprise  and Related
Information,"  establishes  standards for reporting  information about operating
segments.  Operating  segments are defined as components  of an enterprise  that
engages in business activities from which it may earn revenues and incur expense
and for which  separate  financial  information  is available  that is evaluated
regularly  by the chief  operation  decision  maker in deciding  how to allocate
resources and in assessing performance.
   The Company provides a comprehensive  range of network  solutions to meet its
customers'  needs by  cross-selling  a variety of services,  including  Internet
connectivity  services,  value-added services,  systems integration and sales of
network-related  equipment. The Company's chief operating decision maker, who is
the Company's Chief Executive Officer, regularly reviews the revenue and cost of
sales on a  consolidated  basis and makes  decisions  regarding  how to allocate
resources and assess performance based on a single operating unit.

2. OTHER INVESTMENTS

   Pursuant to SFAS No. 115, all of the Company's  marketable equity securities,
principally  marketable  shares  of common  stock of  Japanese  companies,  were

                                      -21-


6. COMMITMENTS AND CONTINGENT LIABILITIES

   The Company adopted FASB Interpretation No. 45,  "Guarantor's  Accounting and
Disclosure  Requirements  for  Guarantees,   Including  Indirect  Guarantees  of
Indebtedness  of Others" ("FIN 45"). FIN 45 elaborates on the  disclosures to be
made by a guarantor  about its  obligations  under certain  guarantees.  It also
clarifies  that a guarantor  is required to  recognize,  at the  inception  of a
guarantee,  a  liability  for the fair  value of the  obligation  undertaken  in
issuing the guarantee.
   In December 2001, a class action complaint alleging violations of the federal
securities  laws was filed  against  the  Company,  naming  IIJ,  certain of its
officers and directors as defendants,  and  underwriters of IIJ's initial public
offering. Similar complaints have been filed against over 300 other issuers that
have had initial public offerings since 1998 and such actions have been included
in a single  coordinate  proceeding  in the  Southern  District of New York.  An
amended complaint was filed on April 24, 2002 alleging, among other things, that
the  underwriters of IIJ's initial public offering  violated the securities laws
(i) by failing to  disclose in the  offering's  registration  statement  certain
alleged compensation  arrangements entered into with the underwriters'  clients,
such as undisclosed  commissions  or tie-in  agreements to purchase stock in the
after-market,  and (ii) by engaging in  manipulative  practices to  artificially
inflate the price of IIJ's stock in the  after-market  subsequent to the initial
public offering.  On July 15, 2002, the Company joined in an `omnibus' motion to
dismiss the amended  complaint filed by the issuers and individuals named in the
various  coordinated cases. In June 2003, the Company approved a settlement with
the  plaintiffs  in this  matter.  In June  2004,  the  Company  along  with the
plaintiffs,  the insurers, and virtually all of the other District Court for the
Southern District of New York for preliminary approval.  The settlement releases
IIJ and the individual  defendants for liability for the conduct  alleged in the
action. Under the settlement,  the Company agreed to assign away, not assert, or
release   certain   potential   claims  the  Company  may  have  against   IIJ's
underwriters.   Approximately  260  defendant   issuers   participated  in  this
settlement.  As to financial impact on the Company, the settlement provides that
the class members will be guaranteed $1 billion in recoveries by the insurers of
the issuers.  In addition to IIJ's portion of the proposed  settlement,  some of
the continuing legal expenses incurred in connection with the partial settlement
would be  borne  by IIJ's  insurer  based  on the  settlement  agreement  and an
individual  agreement between IIJ and IIJ's insurer.  Consequently,  the Company
believes that there will be no significant  financial impact on the Company as a
result of this matter.  This  settlement  requires  final  approval  from United
States of America district court.
   In  addition  to the  foregoing,  the  Company is a party to other  suits and
claims that arise in the normal course of business. The negative adverse outcome
of such suits and claims would not have a  significant  impact on the  financial
statements.

7. DERIVATIVE AND OTHER FINANCIAL INSTRUMENTS

Interest Rate Swap Agreement

   The Company is exposed to changes in interest rates that are associated  with
long-term bank  borrowings.  The Company's  policy on managing the interest rate
risk is to hedge the  exposure to  variability  in future cash flows of floating
rate interest payments on the long-term bank borrowings. In order to reduce cash
flow risk exposures on floating rate borrowings,  the Company utilizes  interest
rate swap  agreements  to  convert a  floating  rate  borrowing  to a fixed rate
borrowing.
   The  Company  is also  exposed  to  credit-related  losses  in the  event  of
non-performance by counterparties to interest rate swaps, but it is not expected
that  any  counterparties   will  fail  to  meet  their   obligations,   because
counterparties are internationally recognized financial institution.

   Changes  in  fair  value  of  interest  rate  swaps   designated  as  hedging
instruments is reported in  accumulated  other  comprehensive  income during the
first  quarter  of FY2005,  and full  FY2004.  These  amounts  subsequently  are
reclassified  into interest  expense as a yield adjustment in the same period in
which the hedged bank borrowings affect earnings. The term, notional amount, and
repricing  date of interest  rate swaps  exactly  match  those of the  long-term
borrowings.  The swap  terms are "at the  market,"  so they  have zero  value at
inception.  Thus,  there was no  ineffectiveness  recognized  in earning for the
first quarter of FY2005 and full FY2004.  At June 30, 2005, the notional  amount
of interest  rate swap  contracts  amounted to JPY 1,400,000  thousand,  and net
derivative loss on those contracts totaled JPY 9,347 thousand.

Overview of 2nd Quarter of FY2005 Financial Results and Business
Outlook(2)
----------------------------------------------------------------------

    "The favorable trend of increasing revenues and profits continued
in 2Q05," said Koichi Suzuki, President and CEO of IIJ. "Total
revenues jumped 13.5% compared to the same period last year and 20.7%
sequentially mainly due to continued increases in sales of
higher-margin network outsourcing and systems integration ("SI"). This
was largely a reflection of the direction that we see the market and
our business heading. Corporate customers are continuously requiring
ever higher quality IP engineering skills and resources due to the
constantly increasing volume of Internet traffic, escalating network
and security threats, and expansion of internal network systems that
are integrated with the Internet. In particular, SI in 2Q05 increased
significantly because we succeeded in acquiring a number of new
systems integration projects, including the connection of customers'
sites with broadband lines, the construction and operation of a new
mail server to assist customers with their continuously increasing
number of e-mails, and the construction and operation of security
systems for several customers to bolster their efforts at fighting
spam and external attacks."
    "We are pleased that we successfully exceeded our initial targets
for the first half of the fiscal year," said Akihisa Watai, CFO of
IIJ. "We maintain our initial targets at this moment since we
generally receive the largest portion of our SI revenues in the fourth
quarter of our fiscal year."

5,767 million in 2Q05, an increase of 4.7 % from JPY 5,508 million in
2Q04 and almost flat compared to JPY 5,767 million in 1Q05.
    Dedicated access service revenues were JPY 2,695 million in 2Q05,
a decrease of 4.8% compared to 2Q04 and a decrease of 1.9% compared to
1Q05. The decrease was mainly due to the failure of an increase in
revenues from broadband services to offset a decrease in revenues from
T1 Standard or IIJ Economy.
    Dial-up access service revenues were JPY 683 million in 2Q05, a
decrease of 7.8% compared to 2Q04 and a decrease of 2.3% compared to
1Q05. The decrease from 2Q04 and 1Q05 is mainly due to the decrease in
revenues from IIJ4U and OEM service revenues.
    VAS revenues were JPY 1,459 million in 2Q05, an increase of 19.5%
compared to 2Q04 and an increase of 5.1% compared to 1Q05. The
increase compared to 2Q04 and 1Q05 is mainly due to an increase in
revenues from various types of packaged outsource services, such as
security, e-mail and web hosting and network services such as managed
router services.
    Other revenues were JPY 930 million in 2Q05, an increase of 30.0%
compared to 2Q04 and a decrease of 0.3% compared to 1Q05. The increase
from 2Q04 is mainly due to an increase in revenues from Wide-area
Ethernet Services.
    SI revenues increased 34.5% to JPY 5,162 million in 2Q05 from JPY
3,838 million in 2Q04 and increased 34.4% from JPY 3,840 million in
1Q05. The increase from 2Q04 is mainly due to additional revenues from
the purchase of the security system business operations of Yamatane
Co. Ltd. in October 2004 and solid growth of revenues from outsourced
operations. The increase from 1Q05 is mainly due to the significant
increase in revenues from systems development projects and solid
increase of revenues from outsourced operations.
    Equipment sales revenues were JPY 1,000 million in 2Q05, a
decrease of 14.2% compared to 2Q04 and an increase of 266.0% compared
to 1Q05. The increase from 1Q05 is due to the increase of sales of
network equipment related to new system integration projects.

increase of 4.3% compared to 2Q04 and almost flat compared to 1Q05.
The increase from 2Q04 is mainly due to an increase in personnel
expenses and cost for local access lines for Wide-area Ethernet
Services. The gross-margin ratio for Connectivity and VAS in 2Q05 was
13.5%, compared to 13.2% in 2Q04 and 13.9% in 1Q05. The improvement
from 2Q04 was mainly due to an increase in revenues from higher-margin
VAS, and a decrease in backbone costs.
    Cost of SI revenues was JPY 3,919 million in 2Q05, an increase of
31.4% compared to 2Q04 and an increase of 34.7% compared to 1Q05. The
gross margin ratio for SI in 2Q05 was 24.1%, compared to 22.3% in 2Q04
and 24.2% in 1Q05. The improvement in margin compared to 2Q04 was
mainly due to the increase in higher-margin systems integration
contracts.
    Sales and marketing expenses were JPY 800 million in 2Q05, an
increase of 12.4% compared to 2Q04 and an increase of 4.1% compared to
1Q05. The increase from 2Q04 is mainly due to an increase in
advertising and personnel expenses. The increase from 1Q05 is mainly
due to an increase in advertising expenses.
    General and administrative expenses were JPY 699 million in 2Q05,
an increase of 14.1% compared to 2Q04 and a decrease of 2.1% compared
to 1Q05. The increase from 2Q04 is mainly due to an increase in
personnel expenses.

Operating income
----------------

    Operating income was JPY 507 million in 2Q05, compared to JPY 282
million in 2Q04 and JPY 247 million in 1Q05. The increase from 2Q04
and 1Q05 was mainly due to increased gross-margins in Connectivity,
VAS and SI.
    Other income (expenses) in 2Q05 was other income of JPY 590
million, compared to other expenses of JPY 10 million in 2Q04 and
other income of JPY 435 million in 1Q05. The increase from 2Q04 and
1Q05 is mainly due to an increase in gain from sale of
available-for-sale securities. The differences from 2Q04 also include
the absence of interest payments for the convertible notes due March
31, 2005.
    Income tax expense for 2Q05 was JPY 44 million, compared to JPY 16
million in 2Q04 and JPY 38 million in 1Q05.

    About Internet Initiative Japan Inc.
    Founded in 1992, Internet Initiative Japan Inc. (IIJ, NASDAQ:
IIJI) is one of Japan's leading Internet-access and comprehensive
network solutions providers. The company has built one of the largest
Internet backbone networks in Japan, and between Japan and the United
States. IIJ and its group of companies provide total network solutions
that mainly cater to high-end corporate customers. The company's
services include high-quality systems integration and security
services, Internet access, hosting/housing, and content design.

    Statements made in this press release regarding IIJ's or
management's intentions, beliefs, expectations, or predictions for the
future are forward-looking statements that are based on IIJ's and
managements' current expectations, assumptions, estimates and
projections about its business and the industry. These forward-looking
statements, such as statements regarding FY2005 revenues and operating
and net profitability, are subject to various risks, uncertainties and
other factors that could cause IIJ's actual results to differ
materially from those contained in any forward-looking statement.
These risks, uncertainties and other factors include: IIJ's ability to
maintain and increase revenues from higher margin services such as
system integration and value-added services; the possibility that
revenues from connectivity services may decline substantially as a
result of competition and other factors; the ability to compete in a
rapidly evolving and competitive marketplace; the impact on IIJ's
profits of fluctuations in costs such as backbone costs and
subcontractor costs; the impact on IIJ's profits of fluctuations in
the price of available-for-sale securities; the impact of
technological changes in its industry; IIJ's ability to raise
additional capital to cover its indebtedness; the possibility that
NTT, IIJ's largest shareholder, may decide to exercise substantial
influence over IIJ; and other risks referred to from time to time in
IIJ's filings on Form 20-F of its annual report and other filings with
the United States Securities and Exchange Commission.

(1) Unless otherwise stated, all financial figures discussed in this
    announcement are prepared in accordance with U.S. GAAP. All
    financial figures are unaudited and consolidated. For all 2Q05 and
    1H05 results, translations of Japanese yen amounts into US dollars
    are solely for the convenience of readers outside of Japan and

    figures have been restated to reflect the change in income tax
    expense (benefit) previously announced by IIJ in its press release
    dated April 11, 2005.
(2) This Overview and Business Outlook contains forward-looking
    statements and projections such as statements regarding FY2005
    revenues and operating and net income that are subject to known
    and unknown risks and uncertainties that could cause actual
    results to differ materially from those expressed or implied by
    these statements. These risks and uncertainties include, but are
    not limited to, the factors noted at the end of this release and
    to the risk factors and other information included in IIJ's annual
    report on Form 20-F, filed with the SEC on August 3, 2005, as well
