                                                                       Exhibit 1

     IIJ Announces Second Quarter Results for the Year Ending March 31, 2004

    TOKYO & NEW YORK--(BUSINESS WIRE)--Nov. 20, 2003--Internet
Initiative Japan Inc. (Nasdaq:IIJIE) ("IIJ"), one of Japan's leading
Internet access and comprehensive network solutions providers, today
announced its financial results for the 2nd quarter of the fiscal year
ending March 31, 2004 ("Fiscal Year 2003").

    Second Quarter FY2003 Highlights(1)

    2nd Quarter FY2003:

    --  Revenues totaled JPY 9,185 million ($ 82.4 million), an
        increase of 10.1% from JPY 8,344 million in 1Q03, though a
        decrease of 13.1% compared to 2Q02. The increase from 1Q03 is
        mainly due to revenue increases from Systems Integration
        ("SI"), Data Center and other value-added services.

    --  Operating loss was JPY 830 million ($ 7.4 million), a decrease
        from 1,206 million in 1Q03 and an increase from JPY 194
        million in 2Q02. The loss includes accounts receivable
        write-offs of JPY 287 million that related to transactions
        with Crosswave Communications Inc. ("Crosswave"), a former
        equity method affiliate of IIJ. The improvement in operating
        loss from 1Q03 was mainly due to increased SI profitability
        and a reduction of domestic backbone costs.

    --  Adjusted EBITDA(2)was JPY 126 million ($ 1.1 million), an
        increase from the JPY 243 million adjusted EBITDA loss in
        1Q03, though a decrease from JPY 662 million in 2Q02.

    --  On August 20, Crosswave filed a voluntary petition for the
        commencement of corporate reorganization proceedings in Japan.
        IIJ has written-off all of its investments in, deposits for,
        loans to and accounts receivable due from Crosswave regarding
        the above through the end of this quarter. As a result of
        Crosswave no longer being accounted for under the equity
        method, the net loss decreased from JPY 2,326 million in 2Q02
        to JPY 278 million in 2Q03. IIJ will not have further equity
        loss from Crosswave, which in the past had a significant
        negative impact on IIJ's financial statements.

    --  IIJ completed an approximately JPY 12 billion private
        placement to NTT Group, Itochu Corporation, Sumitomo
        Corporation and three other companies on September 17, 2003.
        With this capital injection, the financial impact due to
        Crosswave's reorganization proceedings has been offset. As a
        result, IIJ's shareholders' equity has become positive.

    --  IIJ received notice from Nasdaq that IIJ's American Depositary
        Shares will continue to be listed on the Nasdaq National
        Market, subject to requirements that IIJ file its annual
        report on Form 20-F for the fiscal year ending March 31, 2004
        with the U.S. Securities and Exchange Commission and Nasdaq on
        or before September 30, 2004, and the IIJ demonstrate
        compliance with all requirements for continued listing on the
        Nasdaq National Market throughout this period. The fifth
        character "E" will remain appended to IIJ's trading symbol
        pending confirmation that IIJ has evidenced full compliance
        with Nasdaq's filling requirement and all other requirements
        for continued listing on the Nasdaq Stock Market.

    Outlook:

    --  By improving gross-margins and expanding SI service revenues,
        IIJ expects to reach a break-even level of operating income in
        3Q03 and to achieve positive operating income in 4Q03. In
        addition, IIJ expects an additional one-time increase in
        "other income" of approximately JPY 1.6 billion in 3Q03 from
        the sales of our shares of DLJdirectSFG Securities Inc. and
        approximately JPY 120 million by repurchasing and canceling a
        portion of IIJ's convertible notes that are due in 2005.

    Overview of 2nd Quarter FY2003 Financial Results and Business
Outlook(3)

    Financial Results and Business Outlook

    "As Japan's economy is beginning to show indications that it is in
a recovery phase, there seems to be an environment where Japanese
corporate customers are considering investing in their networks," said
Koichi Suzuki, President and CEO of IIJ. "With the rapid changes in
corporate networks, as expansion of broadband and increasing
complexity, Japanese corporate customers are focusing more on in-house
networks including the gateway to Internet. For example, Japanese
companies are starting to use the latest network technology to connect
branch offices or other sites at higher speeds with lower cost,
increasing security on Internet traffic and outsourcing the operations
of network equipment and servers. We are currently changing our SI
development and business to meet those demands rapidly. We call this
"Network Integration". Our strategy in the coming quarters is to seek
new source of revenue by cross-selling these new solutions to meet the
requirements of our current connectivity customers".
    Koichi Suzuki continued, "On September 17, we completed the
private placement to third parties to improve our capital structure,
and NTT Group became our largest shareholder holding 31.6%. While we
will retain our operating independence even after the private
placement, we are going to have a collaborative relationship with NTT
in the technological development and sales partnership".
    "In 2Q03, revenues recovered compared to 1Q03, mainly driven by
sales of SI, Data Center Services and other value-added services",
said Yasuhiro Nishi, CFO of IIJ. "We have succeeded in acquiring new
customers for network integration services, and the revenue from these
cases will be accounted for in 3Q03. By continuing to expand in the
higher-margin SI area and cross-selling to customers as well as
reducing costs, we will keep on track for a recovery in profitability
and hopefully achieve positive operating income in the second half of
the year".
    Yasuhiro Nishi also stated, "As for Crosswave's commencement of
reorganization proceedings, we have written off all investments in,
deposits for, loans to and accounts receivable due from Crosswave
regarding the above through this quarter. We believe that the private
placement on September 17 will cover the financial impact of
Crosswave's reorganization, and we will not have further equity losses
from Crosswave, which in the past had a significant negative impact on
IIJ's financial statements".

    Recent Trends in Major Services and Contracts

    As for connectivity services, there appears to be new demand for
broadband services such as using these services for access lines for
site connectivity utilizing Internet VPN technology. IIJ has already
acquired several customers for these services connecting over 100
sites. In addition to proposing bandwidth upgrades to existing
customers and approaching new customers, we expect these new demands
might help us to maintain current levels of revenue of connectivity
services, as well as related network integration and equipment sales.
    Revenues for SI services benefited as IIJ won several network
integration customers from the manufacturing and financial sectors.
The major contents of the integration work was mail and web gateway
services that control outgoing and incoming e-mails and web access,
server housing in Data Centers and outsourcing of operation and
network consultation for disaster recovery. Also, we increased
revenues from equipment sales, such as database servers, web servers,
data storage and firewall equipment.

decreased by 6.5% in 2Q03 compared to 2Q02 and decreased by 2.0%
compared to 1Q03, mainly due to the decline of unit prices despite an
increase in the number of contracts. Customers continued to shift from
dedicated line-based connectivity services such as IIJ T1 Standard and
IIJ Economy, to lower-cost broadband services such as IIJ
FiberAccess/F service (Maximum 10-100Mbps), and the increase in IIJ
FiberAccess/F service did not offset the decrease in IIJ T1 Standard
and IIJ Economy.

    Cost of connectivity and value-added services was JPY 5,127
million, an increase of 0.9% compared to 2Q02 and a decrease of 2.1%
compared to 1Q03. The gross margin ratio for connectivity and
value-added services in 2Q03 was 9.1%, compared to 10.8% in 2Q02 and
6.5% in 1Q03. The improvement of the gross margin ratio compared to
1Q03 was as a result of our effort for overall cost reduction such as
backbone costs, the expense for network nodes and office rent
expenses.
    International backbone costs were JPY 247 million, a decrease of
44.8% compared to 2Q02 and a decrease of 5.2% compared to 1Q03. The
monthly unit backbone costs per Mbps declined by 61% compared to 2Q02
and by 29% compared to 1Q03.

Domestic Backbone Costs                993  815   21.9% 1,057   (6.0%)
----------------------------------------------------------------------


    Domestic backbone costs were JPY 993 million, an increase of 21.9%
compared to 2Q02 and a decrease of 6.0% compared to 1Q03. The
year-over-year increase was due to an increase in connection fees with
NTT's regional access networks (FLET'S), along with our broadband
strategy to strengthen our backbone network to provide various
broadband network services and solutions nationwide.
    Cost of SI Revenues was JPY 2,275 million in 2Q03, a decrease of
15.1% compared to 2Q02 and a decrease of 2.1% compared to 1Q03. The
gross margin for SI deteriorated to 10.7% in 2Q03 compared to 13.3% in
2Q02 but improved from 3.5% in 1Q03. The gross margin ratio in 2Q03
improved compared to 1Q03 because of improvement of profitability in
SI development contracts.
    Sales and Marketing Expenses were JPY 1,100 million in 2Q03, an
increase of 47.9% compared to 2Q02 and an increase of 13.0% compared
to 1Q03. The 2Q03 expenses include the written-off accounts receivable
due from Crosswave, which amounted to JPY 287 million.
    General and administrative expenses were JPY 482 million in 2Q03,
a decrease of 6.2% compared to 2Q02 and a decrease of 21.2% compared
to 1Q03. The 1Q03 expenses included the cost of the move to new
headquarters.

    Operating loss

    Operating loss increased to JPY 830 million in 2Q03 compared to a
loss of JPY 194 million in 2Q02. The increase is primarily due to the
write-off of accounts receivable from Crosswave and a decrease in
connectivity service revenues. The operating loss in 2Q03 declined
compared to a loss of JPY 1,206 million in 1Q03, due to improved
profitability in IIJ's SI business.
    Other expenses for 2Q03 were JPY 157 million, compared to JPY 160
million in 2Q02 and JPY 204 million in 1Q03. IIJ recorded a gain on
sales of available-for-securities, which amounted to JPY 47 million in
2Q03.
    Income tax benefit (expense) for 2Q03 was a benefit of JPY 572
million, compared to an expense of JPY 515 million in 2Q02 and a
benefit of JPY 390 million in 1Q03. This is due to a decrease in the
valuation allowance for deferred tax assets attributable primarily to
the income tax effect of increasing unrealized gains during the
quarter on certain available-for-sale securities.
    Equity in net loss of equity method investees amounted to JPY 50
million in 2Q03, compared to JPY 1,480 million in 2Q02, and JPY 1,709
million in 1Q03. The equity in net loss of Crosswave is included in
the equity in net loss of equity method investees in 1Q03 and 2Q02,
but not included in 2Q03.
    Net loss was JPY 278 million in 2Q03, compared to JPY 2,326
million in 2Q02 and JPY 2,475 million in 1Q03. The decreases in net
loss was a result of the increasing income tax benefit reflecting the
increasing unrealized gains on available-for-sale securities and the
absence of equity method loss in Crosswave due to the full write-down
of IIJ's equity investment in Crosswave. Basic net loss per ADS
equivalent was JPY -5.04 in 2Q03, compared to JPY -51.74 in 2Q02 and
JPY -54.72 in 1Q03.

    2nd Quarter FY2003 Business Review

    Service Development

    Outsourcing Solutions: Under IIJ Technology, the IIJ Group further
expanded its Integration & Business Platform Service (IBPS) product
line. IBPS is a service offered to corporate customers which allows
them to combine ready-made network service components with
integration. These components include network equipment, controlling
functions of outgoing and incoming Internet traffic (virus check,
auditing and archiving e-mails and controlling web-access), data
storage, operational resources, etc. By providing these components on
demand at the Group's data centers and allowing customers to use these
network components without having to purchase them, IIJ's corporate
customers can launch the network systems more smoothly and cost
effectively. In October 2003, IIJ Technology started to provide over
40 terabyte storage service.
    Network Management Solutions: In 2Q03, we began "IIJ
NetLightning", based on Netli, Inc's technology which improves web
application performance. By using IIJ NetLightning, end users can more
quickly access to customer websites and customers can reduce the cost
to set up mirror sites.
    Also in June 2003, IIJ launched IIJ SMF (SEIL Management
Framework), a service which provides remote configuration and
monitoring features for IIJ's high-end SEIL/neu Series routers at
customer remote sites from central management servers at IIJ and
customer main office/data center. SMF, the technology used for this
service is patent pending.
    Hosting Services: In 2Q03, we began "IIJ Document Exchange
Service" for medium and small-sized corporate customers. This service
allows the creation of virtual folders on Internet, and customers to
share files with workers outside the office or with commercial
partners.

    Network Infrastructure Development and Optimization

    In 2Q03, IIJ increased the capacity of ten of its domestic
backbone network lines and also established two new lines. IIJ also
increased the capacity of three U.S. backbone network lines and
established one additional U.S. backbone network line to maintain
current throughput and quality. At the same time, from a cost point of
view, IIJ is now trying to optimize the network in accordance with the
number of customers connected to the network nodes, and has ceased the
operations of several network nodes for dedicated line-based Internet
connectivity services.

    Finance

    Financial Impact of Crosswave's Commencement of Reorganization
Proceedings:

    On August 20, Crosswave filed a voluntary petition for the
commencement of corporate reorganization. In light of Crosswave's
reorganization, IIJ has fully written-off the accounts receivable due
from Crosswave prior to entering corporate reorganization, amounting
to JPY 287 million in 2Q03. As a result, IIJ has fully written-off the
remaining value of its investment in and deposits for, loans to and
accounts receivable due from Crosswave through the end of this
quarter.

    Capital Improvement Plan:

    On September 17, 2003, IIJ completed a private placement to NTT
Group, Itochu Corporation, Sumitomo Corporation and three other
companies for a total amount of approximately JPY 12 billion. With
this capital injection, the financial impact of Crosswave's
commencement of reorganization has been offset and IIJ's shareholders'
equity has turned positive.

    Key Developments of the IIJ Group

    IP*VLAN

    In November 2003, IIJ developed and announced a new technology
called, IP*VLAN (Internet Protocol-Virtual Local Area Network). This
technology is for the construction and management of layer 2 networks
over existing IP networks (layer 3) for Internet or corporate users.
It enables PCs and other client devices to connect to the same LAN,
regardless of distances between offices, and it enables access control
for all services without requiring client certification (patent
pending).

    Teleconference/Webcast

    On November 21 at 9:00 am (EST), IIJ will host a conference call
to discuss the results and the Company's outlook. There will be a
simultaneous webcast available at www.vcall.com. A replay will also be
available at the same URL.
