            Expected Continued Revenue Growth and Positive
                       Operating Margin in 2003

    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 4th quarter and full
fiscal year 2002, ending March 31, 2003 ("fiscal 2002").
    On May 21 at 9:00 am (EST), the Company will host a conference
call to discuss the results and its outlook. There will be a
simultaneous webcast available at www.vcall.com. A replay will also be
available at the same URL.



The 4th Quarter and full fiscal year 2002 Results Summary
----------------------------------------------------------------------

4th Quarter 2002:

    Revenues totaled JPY 13 billion ($ 110 million), an increase of
    7.7% compared to 4Q01 and 23.4% from 3Q02.  Despite the lethargic
    Japanese economy, IIJ was able to maintain its steady growth,
    surpass guidance and achieve the highest total revenue amount in
    the Company's history.

    Operating loss narrowed to JPY 446 million ($ 3.8 million) from
    JPY 567 million in 3Q02.  This  compares to a profit of JPY 186
    million in 4Q01.  The 4Q02 results include a non-recurring expense
    related to the IIJ Group's move to its new headquarters in March.

    Adjusted EBITDA(1) was JPY 459 million ($ 3.9 million), a
    decrease of 52.6% compared to 4Q01 and an increase of 31.5% from
    3Q02.

Full fiscal year 2002:

    Revenues increased to JPY 44 billion ($ 373 million), a 10.3%
    increase from the previous year, which was in line with our
    guidance.

    Operating loss was JPY 1.7 billion ($ 14 million).

    Adjusted EBITDA was JPY 1.8 billion ($ 15 million).

 Outlook:

    For the 2003 fiscal year, IIJ expects total revenues to grow by
    more than 10% compared to fiscal 2002. The Company also
    anticipates that operating margins will move into positive
    territory.

    IIJ expects to raise additional equity capital on June 6, 2003.
    We believe that the equity capital financing in a private
    placement will provide IIJ with the financial means to continue
    the implementation of its growth strategy.


 (1) Adjusted EBITDA represents operating income (loss) plus
  depreciation and amortization. Adjusted EBITDA is provided because
  it is a measure commonly used by investors to analyze and compare
  companies on the basis of operating performance. Adjusted EBITDA is
  not a measurement of financial performance under generally accepted
  accounting principles and should not be construed as a substitute
  for operating income, net income or cash flows from operating
  activities for purposes of analyzing our operating performance,
  financial position and cash flows. Our adjusted EBITDA is not
  necessarily comparable with similarly titled measures for other
  companies.

    Overview of 4Q02 and full fiscal year 2002 Results and Business
Outlook

    Overview

    "Despite a difficult economic climate in fiscal 2002, IIJ has
continued to implement its strategy for achieving greater shareholder
value," said Koichi Suzuki, President and CEO of IIJ. "Our strategy
for the Japanese corporate market has been validated with the addition
of several large-scale contracts, including the Ricoh Group, and we
have achieved a record level of revenues. In fiscal 2002, we invested
heavily in new services that will enable us to increase overall
revenues in fiscal 2003 and beyond. We also worked hard to control our
international and domestic backbone expenses through contract
renegotiations and the rationalization of our infrastructure; we
expect the full benefit of these efforts to generate significant cost
reductions in 2003 and beyond. Furthermore, we believe that the recent
establishment of our Network Integration Division will increase our
penetration in the corporate sector, stimulate corporate network
outsourcing demand and help improve our cross-selling efforts.
Finally, we will soon complete a capital increase that will strengthen
the Company's financial base. We are confident that these measures and
our increased focus on high margin products will position IIJ for
operating and financial success in 2003."

    Operating Profitability

    IIJ's revenues for the fourth quarter were the highest in IIJ's
history and surpassed the Company's guidance. Despite the
non-recurring expenses that were caused by the move to the new
headquarters in March, the operating loss in the fourth quarter
improved from the previous quarter's loss, but was worse than the
operating profit achieved in the same quarter of the previous fiscal
year. The moving expenses are considered an operating cost under US
GAAP.
    Revenue from the full 2002 fiscal year also marked the highest
annual amount in the company's history. "Unfortunately, this was not
sufficient to deliver a full year operating profit. An increase in
certain connectivity services revenues was not sufficient to offset a
loss of connectivity service revenues. This was the result of contract
cancellations by the telecom service arm of regional electric power
company and by the shift of several smaller corporate clients from the
IIJ T1 Standard Service and the IIJ Economy Service to cheaper
services. We do not expect a repeat of such revenue losses and we
believe that we will continue to expand our connectivity revenues as
has been the case for many years. To make up for the loss of revenues,
IIJ launched the OEM service through the CDN (Content Delivery
Network) platform and IIJ VPN Standard, a VPN (Virtual Private
Network) service in the fiscal 2002 year. Though it will take some
time to acquire new customers, we believe that these new services will
contribute to make IIJ more profitable in fiscal year 2003. We expect
total revenues to grow by more than 10% compared to fiscal 2002," said
Yasuhiro Nishi, CFO of IIJ. In addition, we expect to continue to
increase the number of CATV customers. About fifty CATV operators were
connected to IIJ, which represents more than 60% of Japan's CATV
Internet market in the 2002 fiscal year.

    Capital Improvement Plan

    IIJ is planning to issue 8,400 new shares of common stock at a
price of JPY418,200 in a private placement to third parties. The
subscription and payment date for the new shares is expected to be
June 6, 2003. We believe that the capital improvement will secure the
financial means to allow IIJ to continue the implementation of its
growth strategy. "Demonstrating a significant vote of confidence in
IIJ's strategy, several major Japanese institutions will increase
their financial commitment to IIJ while others will contribute capital
for the first time," commented Yasuhiro Nishi. Details for the plan
will be announced when finalized.

    Strategies for Enterprise Markets

    IIJ's focus on the enterprise market, which is based on the
Company's Systems Integration(SI) business and is further supported by
company-wide cross-selling efforts, contributed to the Company's
steady growth in fiscal year 2002. Revenue from the SI business
increased 33% sequentially as a result of strong demand for network
solutions, equipment sales that were directed to the enterprise
market.

    Cross-selling

    IIJ has continued to successfully cross-sell its Value-added,
Systems Integration and Data Center Services to existing users of its
Dedicated Access Services. "With a strategic marketing focus on Data
Center Services and a base of 6,000 corporate customers that value the
quality of our technology and support services, IIJ is well positioned
to further increase our cross-selling rates in 2003," said Yasuhiro
Nishi, CFO of IIJ. In fiscal year 2002, revenues from IIJ's top 150
customers accounted for approximately half of the Company's total
revenues. Cross-selling rates for these customers in fiscal 2002 year
are detailed in the following table.

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


    Change in the Organizational Structure

    In an effort to continuously maintain our competitive advantage,
IIJ brought together parts of IIJ, Crosswave Communications, IIJ
Technology and NetCare in order to create a new division called the
"Network Integration (NI) Division," as of April 1, 2003. This
division groups all technology and information platforms, from the
planning and development to the maintenance and operation of various
services. This division will make it possible to rapidly respond to
demand in the construction of network communication systems for
enterprises.

    Status of Overview and Business Outlook

    This Overview and Business Outlook contains forward-looking
statements and projections, such as statements regarding future total
revenues and operating profitability, 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 contained in IIJ's filings on Form 20-F and Form
6-K, as well as other filings and documents furnished to the
Securities and Exchange Commission. IIJ plans to keep this press
release publicly available on its Web site (www.iij.ad.jp), but may
discontinue this practice at any time.

    4th Quarter and full fiscal year 2002 Operating Highlights

    Large-Scale Contracts

    Several major Japanese companies awarded large-scale contracts to
IIJ during the 4th quarter, including the Ricoh Group and Japan
Leisure Channel. In February 2003, IIJ won a large-scale outsourcing
contract for email gateway solutions, "IIJ Mail Gateway service," from
the Ricoh Group, one of the world's leading suppliers of office
automation equipment. In March, the Japan Leisure Channel Co. Ltd.
(JLC) chose the IIJ Group to build and operate a large-scale broadband
motorboat racing site called "Kyotei B.B." where IIJ "CDN JAPAN"
service has been utilized.
    Additionally, IIJ launched "IIJ Web Gateway Service," a new
security service that will be provided in cooperation with IIJ
Technology Inc. (IIJ-Tech), our 64.1% owned subsidiary. The service
meets a variety of enterprise needs by providing proxy-caching server
operation and management functions that boost Web access efficiency.

    Service Development

    IIJ has continued to develop new services. In 4Q02, IIJ developed
the IIJ SEIL Management Framework system (IIJ SMF), the world's first
network service operating system that enables corporations to
substantially automate network configuration, and realize
"plug-n-join" network services to control all networking processes,
including network construction and operation. Customers can enjoy
large cost reductions for the construction of network configurations
by using this system. In addition, IIJ recently launched a new
outsourcing solution of web-access filtering, "IIJ URL Filtering
Service," to enable corporate customers to block access from their
internal network to undesirable web sites in order to improve their
productivity. IIJ's subsidiary, Net Care, Inc., launched a new IP
(Internet Protocol) telephony solution service for enterprises. The
new service provides a comprehensive VoIP (Voice over IP) solution
that seamlessly integrates the operation of telephone and data
networks. The service includes consulting, equipment selection, system
construction and implementation, supervision, operation and
maintenance.

    Data Center

    In January 2003, Crosswave Communications Inc. (a company which
IIJ owns 37.9%) opened new data centers in Yokohama and Saitama.
Unlike conventional data centers, these two new data centers offer a
full range of integrated network and SI (Systems Integration) services
that use the IIJ Group's extensive range of network, system and
engineering resources. The two new data centers are linked to other
IIJ Group data centers nationwide, which help in dispersing capacity
while providing further system back-up.

    Network Infrastructure Development

    In 4Q02, IIJ increased the capacity of seven of its domestic
backbone network lines. IIJ also upgraded its US backbone network that
runs between Los Angeles, California and Ashburn, Virginia.

    R&D (IPv6)

    In March 2003, IIJ launched a new IPv6 (Internet Protocol Version
6) service called "IPv6 Gateway Service". The new service will target
leading companies in a variety of different industries. Besides
offering IPv6 connectivity through IIJ's network, the service provides
approximately 3 x 10 to the 26th power IP addresses (a block of /40)
per contract, which enables customers to roll out their own IPv6
services by assigning an IP address to each of their products or
services. Hitachi Ltd. has already contracted this service from IIJ.

    Appointment of IIJ Engineers as IESG & IAB Members

    In March 2003, two of IIJ's engineers were appointed as Members of
IESG* (Internet Engineering Steering Group) and IAB* (Internet
Architecture Board). Mr. Randy Bush, Chief Scientist of IIJ America,
has become a Member and Area Director of IESG and is responsible for
the Operations & Management area. Dr. Jun-ichiro Itojun Hagino, a
senior researcher in the IIJ Laboratory, is serving as a Member of
IAB. The assignments are two-year terms and are effective from March
2003 until February 2005.

    *IESG and IAB are organizations which are part of the
IETF(Internet Engineering Task Force), which is a large open
international community of network designers, operators, vendors, and
researchers who are concerned with the evolution of the Internet's
architecture and the smooth overall operation of the Internet. The
IETF activities are grouped into eight areas, which are administered
by the IESG Area Directors. The IAB is an international organization
that provides architectural oversight and adjudicates appeals of
complaints.

    4th Quarter of FY2002 Financial Results

    Revenues

    Revenue in 4Q02 totaled JPY13,036 million, an increase of 7.7%
compared to 4Q01, and an increase of 23.4% compared to 3Q02.
    Connectivity and value-added services revenue was JPY5,419 million
in 4Q02, a decrease of 7.3% compared to 4Q01 and a decrease of 2.6%
compared to 3Q02.
    Dedicated access services revenues were JPY3,341 million in 4Q02,
a decrease of 8.3% compared to 4Q01 and a decrease of 1.8% compared to
3Q02. The decrease in year-over-year comparison was mainly due to the
cancellation by the telecom service arm of a regional electric power
company, but in sequential comparison, the downward trend in dedicated
access services is being compensated by the rapid revenue growth of
IIJ FiberAccess/F service(10-100Mbps) and the steady growth of Data
center connectivity service.
    Dial-up access service revenues were JPY765 million in 4Q02, a
decrease of 9.4% compared to 4Q01 and a decrease of 1.4% compared to
3Q02. The revenues of IIJ's various OEM services, which include NTT's
regional L-mode service and other network services that use the CDN
platform, increased steadily, which offset the decline of IIJ4U
service and other dial-up services for corporate customers.
    Value-added services revenues increased 13.2% to JPY931 million in
4Q02 compared to 4Q01 and 2.0% compared to 3Q02. These increases were
mainly due to the revenue growth of security related services.
    Systems integration service revenues decreased 8.0% to JPY4,905
million in 4Q02 compared to 4Q01, but increased 33.2% compared to
3Q02.
    Equipment sales revenues were JPY2,712 million in 4Q02, an
increase of 190.4% compared to 4Q01 and an increase of 105.7% compared
to 3Q02. These revenues included sales of network equipment for the
educational industries and governmental agencies, which we expect to
develop as significant clients for our SI business.
