             Announcement: Additional Acquisition of Hudson Shares


Konami Corporation ('Konami') announced today that, pursuant to resolutions
adopted at meeting of the Board of Directors of Konami, held on April 11, 2005,
Konami will support HUDSON SOFT CO., LTD., ('Hudson') by accepting a third party
allotment of new shares of Hudson, an equity method affiliate of Konami. As a
result, Hudson will become a consolidated subsidiary of Konami.



1.       Objective of Acquiring Additional Hudson Shares



Hudson expects to record a large loss in the fiscal year ended March 31, 2005,
which is expected to result in a substantial reduction in its net worth, and it
requested the assistance of Konami in connection with the reorganization of its
business and operations. Konami expects its acquisition of additional shares
will strengthen Hudson's net worth and will support and enhance its
reorganization. Konami has decided to accept a third party allotment of
3,000,000 new shares of Hudson in response to its request. Konami invested in
Hudson in August 2001 and owned approximately 45% of all shares of Hudson at the
end of March 2005. Following the third party allotment of new shares of Hudson,
Konami will own 54% of all shares of Hudson and Hudson will become a
consolidated subsidiary of Konami.
