2.        Reasons for the revision

During the first half of the fiscal year ending March 31, 2003:


•        Yu-Gi-Oh! Dark Duel Stories for the Game Boy Color and Yu-Gi-Oh! Forbidden Memories for the PlayStation,
         released in the U.S. in March this year, have sold well and a total of approximately 1.2 million copies 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.
