2.        Reasons for the revision

Forbidden Memories for the PlayStation2, released in the U.S. in March this
year, have sold well and approximately 1.2 million copies of each product have
been shipped.


•            Yu-Gi-Oh! The Eternal Duelist Soul for the Game Boy Advance,
released in the U.S. in October this year, sold approximately 550,000 copies in
September.

•             Further implementation of cost management strategies have resulted 
in greater cost reductions.


Due to the above reasons, net sales, ordinary income and net income are expected
to surpass the previous forecast for the first half of the fiscal year ending
March 31, 2003.  As a result, Konami Computer Entertainment Japan, Inc. revised
its earnings forecast upwards as shown above.


3.           Forecast for the fiscal year ending March 31, 2003

Konami Computer Entertainment Japan, Inc. will announce its earnings forecast
for the fiscal year ending March 31, 2003 with its first half results.
