The story said that Sega will announce the plan later this month. Back in October, Sega announced it would provide games for competing consoles, but did not cite any consoles by name.
Jiji's report also said that that Sega may develop titles for the Xbox as well, but no mention was made of plans to support Nintendo.
Sega's stock hit a high of 1,270 yen yesterday, before ending the morning session at 1,263 yen. Shares in Sega are still down nearly 70%, however, from one year ago.
Officials at Sega declined to comment on Jiji's report.
