According to one Japanese retailer who deals in import games (i.e. from the US), they’ve tested the following US Xbox 360 games on Japanese in-store demo 360 systems and confirmed them to work

Call of Duty 2 (Activision)
Condemned Criminal Origins (Sega)
Gun (Activision)
Tony Hawk American Wasteland (Activision)
