The software update, which is scheduled for release later this year, will allow Xbox 360 consoles around the world to output game and movie content in 1080p.
Microsoft also announced the pricing for its Xbox 360 HD-DVD player in Japan, which will cost around 19,800 Yen when it is released on 17 November. The additional drive will come with a Universal Media Remote for the Xbox 360.
The company made the announcements at the Tokyo Game Show, where it highlighted more than 100 Xbox 360 games that will be available in Japan before Christmas.
"The key to winning the hearts and minds of the Japanese market is great games, and this line-up demonstrates that Xbox 360 has those games in spades," said Peter Moore, corporate vice president at Microsoft's Interactive Entertainment Business.
