IIJ Achieves Increased Revenues and Substantially Improved Profits in
                      the First Half of FY2004;
        Growth Expected to Continue in Total Network Solutions

    TOKYO & NEW YORK--(BUSINESS WIRE)--Nov. 11, 2004--Internet
Initiative Japan Inc. (Nasdaq:IIJI) ("IIJ"), one of Japan's leading
Internet-access and comprehensive network solutions providers, today
announced its financial results for the second quarter of the fiscal
year ending March 31, 2005 ("FY2004").(1)

    Highlights of Second Quarter FY2004 Results

    --  Revenue totaled JPY 10,512 million ($95.4 million), an
        increase of 14.4% from JPY 9,185 million in 2Q03 and an
        increase of 21.2% from JPY 8,675 million in 1Q04.

    --  Operating income turned positive to JPY 282 million ($2.6
        million) from an operating loss of JPY 830 million in 2Q03 and
        JPY 100 million in 1Q04.

    --  Revenue in the first half of FY2004 ("1H04") increased by 9.5%
        compared to 1H03. Operating and net income turned positive in
        the first half of the fiscal year, which is usually weaker
        part of the fiscal year compared to the second half. Operating
        income in 1H04 was JPY 182 million, and net income in 1H04 was
        JPY 1,162 million.

    Outlook for FY2004

    --  We expect that the trend of growing positive operating income
        will continue into 3Q04.

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

    "We had a very solid first half of FY2004 and completed a rather
significant turnaround compared to 1H03," said Koichi Suzuki,
President and CEO of IIJ. "We are confident that our network solutions
business is starting to flourish. The demand from corporate customers
for more comprehensive and reliable network solutions is growing and
the trend of improving corporate IT spending continues. Our strategy
is to capture new total network solutions business from existing and
new blue-chip customers. We are particularly geared to providing
various network solutions that are integrated with corporate business
systems, from network design, security consultation and network
implementation, to project management and outsourced operations. For
example, we acquired contracts of Internet VPN based connectivity for
over 1,200 sites in 2Q04 and SEIL Management Framework ("SMF")(3) for
over 3,000 sites since 1H03. Additionally, we recently signed
agreements with several major telecommunications carriers, such as NTT
Communications Corporation ("NTT Communications") and Kyushu
Communications Network Co., Inc ("QTNet") for SMF and SEIL to be
distributed for their Internet VPN service or managed services for
their corporate customers."
    "In 2Q04, we also made significant progress in breaking into the
financial services industry," continued Koichi Suzuki. "In October
2004, the security system business of Yamatane Co.,Ltd. ("Yamatane")
was transferred to IIJ Financial Systems Inc. ("IIJ Financial
Systems"), a newly established company that is 100% owned by IIJ
Technology Inc. ("IIJ Technology"), our subsidiary that manages IIJ's
systems integration business. The finance industry in Japan is
expected to expand considerably as the market sees an increase in
deregulation, such as the abolishment of laws barring banks from
providing their customers with securities trading services. As a
result, we are forecasting an increase in network usage and higher
demand for network and outsourcing services. This combination of
market demand and our focus on a strategy of providing total network
solutions, along with continued emphasis on effective cost management,
will contribute to continued increases in profitability in the third
quarter and beyond."
    "As planned, we achieved an increase in revenues in 2Q04 compared
to 2Q03 and 1Q04", said Akihisa Watai, CFO of IIJ. "At the same time,
we substantially improved profits in 1H04, due to the increase of
revenues in value-added services ("VAS") and systems integration
("SI"), as well as successfully reduced fixed costs including backbone
costs. We believe that we have successfully positioned ourselves for
steady operational profit growth for the foreseeable future. This
along with increased stable monthly revenues from outsourced
operations as well, and we expect the trend of increasing operating
profitability to continue in the second half of fiscal year, which
typically has stronger SI revenues compared to the first half."

----------------------------------------------------------------------

    Connectivity and VAS revenues were JPY 5,508 million in 2Q04, a
decrease of 2.3% from JPY 5,637 million in 2Q03 and an increase of
1.1% from JPY 5,450 million in 1Q04.
    Dedicated access service revenues were JPY 2,832 million in 2Q04,
a decrease of 12.5% compared to 2Q03 and a decrease of 3.0% compared
to 1Q04. The increase in revenue from broadband services did not
offset the revenue decrease from IIJ T1 Standard and IIJ Economy. IP
Service revenues decreased by 10.6% in 2Q04 compared to 2Q03 and
decreased by 2.5% compared to 1Q04 due to the cancellation of the
service by certain large customers. However, we see the trend that the
customers' shift from IIJ T1 Standard and IIJ Economy to broadband
services is being discontinued and with new contracts, we expect the
decrease in dedicated access service revenues to bottom out sometime
in 2H04.
    Dial-up access service revenues were JPY 740 million in 2Q04, a
decrease of 5.6% compared to 2Q03 and a decrease of 1.6% compared to
1Q04 due to the decrease in revenues from IIJ4U.
    VAS revenues were JPY 1,220 million in 2Q04, an increase of 12.9%
compared to 2Q03 and an increase of 2.8% compared to 1Q04, mainly as a
result of the steady increase in security-related services.
    SI revenues increased 50.5% to JPY 3,838 million in 2Q04 from JPY
2,549 million in 2Q03 and increased 42.4% from JPY 2,695 million in
1Q04. The year-over-year growth was as a result of the solid growth of
outsourced operation services, revenue from which increased by 42.8%
to JPY 1,737 million from JPY 1,216 million in 2Q03. The
quarter-over-quarter increase was due to the increasing contracts of
SI development.
    Equipment sales revenues were JPY 1,167 million in 2Q04, an
increase of 16.8% compared to 2Q03 and an increase of 119.8% compared
to 1Q04.

    Cost and expense

    Cost of revenues was JPY 8,854 million in 2Q04, an increase of
6.2% compared to 2Q03 and an increase of 18.9% compared to 1Q04.

----------------------------------------------------------------------

    Cost of Connectivity and VAS revenues was JPY 4,780 million, a
decrease of 6.8% compared to 2Q03 and a decrease of 0.6% compared to
1Q04. The gross-margin ratio for Connectivity and VAS in 2Q04 was
13.2%, compared to 9.1% in 2Q03 and 11.7% in 1Q04 due to a decrease in
backbone costs.
    Cost of SI revenues was JPY 2,983 million in 2Q04, an increase of
31.1% compared to 2Q03 and an increase of 38.3% compared to 1Q04. The
gross margin ratio for SI in 2Q04 was 22.3%, compared to 10.7% in 2Q03
and 20.0% in 1Q04. These improvements were due to the increase in
profitable outsourced operation services.
    Sales and marketing expenses were JPY 712 million in 2Q04, a
decrease of 35.3% compared to 2Q03 and an increase of 7.3% compared to
1Q04. The decrease in 2Q04 compared to 2Q03 was due to a decrease in
bad debt expenses. The expenses in 2Q03 were almost regarding
Crosswave Communications Inc.
    General and administrative expenses were JPY 613 million in 2Q04,
an increase of 27.0% compared to 2Q03 and a decrease of 1.3% compared
to 1Q04. The increase in year-over-year comparison was due to the
increase in personnel expenses and the occurrence of the newly
introduced enterprise tax.

    Operating income

    Operating income was JPY 282 million in 2Q04, compared to an
operating loss of JPY 830 million in 2Q03 and operating loss of JPY
100 million in 1Q04 due to improvements in profitability for
Connectivity, VAS and SI revenues.
    Other expenses for 2Q04 were JPY 10 million, compared to JPY 157
million in 2Q03 and JPY 151 million in 1Q04. The gains on the sale and
exchange transaction of equity investments, which amounted JPY 121
million offset the interest expenses.
    Income tax expense for 2Q04 was JPY 517 million, compared to a
benefit of JPY 572 million in 2Q03 and a benefit of JPY 1,657 million
in 1Q04. The decrease compared to 2Q03 and 1Q04 was due to an increase
in valuation allowance for deferred tax assets attributable primarily
to the income tax effect of decreasing unrealized gain on certain
available-for-securities during the quarter.
    Equity in net income of equity method investees amounted to JPY 16
million in 2Q04, compared to loss of JPY 50 million in 2Q03 and loss
of JPY 11 million in 1Q04.
    Net income (loss) was a loss of JPY 273 million in 2Q04, compared
to a net loss of JPY 278 million in 2Q03 and net income of JPY 1,434
million in 1Q04, in spite of the improvement in operating income, such
income was offset by the increase in income tax expense.

----------------------------------------------------------------------

    In IP Services, the number of contracts for 100Mbps and over is
increasing, since there were customers who shifted to higher bandwidth
within IP Service in order to keep more reliable connectivity for
critical usage such as main lines for corporate headquarters or
upstream for Internet Service Providers. There were 20 customers with
contracts for over 1Gbps, and the total contracted bandwidth topped
100Gbps.
    Broadband services continued to grow rapidly, mainly due to the
new major contracts for multi-site connectivity solutions. A few
examples of the new customers that IIJ acquired in the first half of
FY2004 were: an information distribution company that broadcasts news
to initially approximately 200 sites which might expand to
approximately 3,000 sites in the future, a beverage company that has
network connections between 15 companies, Weathernews Inc., the
world's largest weather information company with branches over 36
cities around the world that broadcasts information via platform built
with Internet VPN and SMF, an electronic-powered tool manufacturer
that has a combination of network with Wide-area LAN and Internet VPN
as backup for connecting approximately 100 sales offices.
    OEM contracts for dial-up access services also increased, since
our OEM partners continued to increase the number of service contracts
in the expanding individual broadband market.

    IP Service revenue declined due to the cancellation of the service
by certain large customers. However, we see the trend that the major
factor that decreased the IP Service revenues in the past,
cancellation of major contracts by a regional electric power company's
telecom service arm is being discontinued. We also see the trend that
the shift of customers from IIJ T1 Standard and IIJ Economy to
broadband services is being discontinued and with newly acquired
contracts, we expect the decrease in dedicated access service revenue
to bottom out sometime in 2H04.
    VAS revenues continued to increase steadily. We had increased
revenues from managed security, network operations, hosting and data
center services. VAS revenues also increased from revenues from SMF
and SEIL rental services due to the acquisition of major contracts for
Internet VPN based connectivity. For SMF, we acquired contracts for
over 3,000 sites since 1H03.
    Backbone costs decreased by 29.3% compared to 2Q03 and by 10.9%
compared to 1Q04. We expect that this trend will continue in 3Q04.

use VAS was 86.9%.
    The cross-selling ratio between Connectivity and SI, as the
percentage of SI customers that use Connectivity services among the
largest 100 SI customers was 80.0%.

    In 1H04, revenues increased primarily in network design and,
configuration and installation of equipment to build multi-site
connectivity with Internet VPN or Wide-area LAN technology to replace
existing Frame Relay network. Revenues also increased in network
planning, security consultation, project management and assistance for
implementation. These services contributed to increase profits, since
we use relatively more internal resources. Stable monthly revenues
from outsourced operation increased as well. We expect the transfer of
security system business of Yamatame by IIJ Technology will effect
positively on our revenue and profits after 3Q04.

    Key Service Developments

    Transfer of security system business of Yamatane to IIJ Financial
Systems:
    On September 17, 2004, IIJ Technology, our subsidiary that manages
IIJ's systems integration services, signed a definitive agreement for
the transfer of security system business of Yamatame. The business was
transferred to IIJ Financial Systems, a newly established company that
is 100% owned by IIJ Technology. The transfer was successfully
completed on October 1, 2004. We believe that the financial services
industry is one area in which we will see particularly strong growth.
The finance industry in Japan is an area in which considerable
expansion is expected as the market sees an increase in deregulation,
such as the abolishment of laws barring banks from providing their
customers with securities trading services. As a result, we are
forecasting an increase in network usage and higher demand for network
and outsourced operating services.

    Addition of anti-spam features to our secure e-mail outsourcing
service:
    In 2Q04, IIJ continued to take the initiative to help fight
against spam in Japan to capture the demands for more secure corporate
information system environment. We started to provide the anti-spam
solutions as an additional feature for our corporate e-mail hosting
services in October 2004.

    Introduction of SMF and SEIL routers to major telecommunication
carriers:
    After 2Q04, IIJ came to agreements with several major
telecommunication carriers for SMF and SEIL to be distributed for
their Internet VPN or managed network services. The carriers include
NTT Communications, QTNet and KVH Telecom Co., Ltd.

    Waive of service fees for victims of natural disasters:

    Since 2Q03 as a company to provide public telecommunication
services, IIJ has waived the service fees for individual dial-up
services for individuals in areas where the Disaster Relief Law was
invoked due to the natural disasters that occurred during this period.
The financial impact by the waive was or will be small since the unit
price for our individual customers is relatively low compared to the
unit price for our corporate customers.
