Few details have been revealed about what to expect for now, but it appears to be taking place from 9PM local time on September 24th, and will immediately follow the opening of the event.
As you can see from the timeline above, Xbox will be in good company - the likes of Square Enix, Capcom, SEGA, Konami and Bandai Namco are all set to feature over the four days.
This marks the latest in a set of major strides Microsoft has made to improve Xbox's position in Japan, including launching Xbox Game Pass in the region earlier this year, and confirming that the Xbox Series X will be available in the country this November instead of being delayed like the original Xbox One.
