I'd also love to know some more fun\unique Japanese released games, that don't really require reading skills (Beyond figuring out controls and menus).
I am currently enjoying Densha de Go! Shinkansen EX... kind of relaxing, would love to see more console simulators (flight, train, boat, bus...). Before MLB PowerPros came out, Jikkyou Powerful Pro Baseball on DS was my first introduction to the Pawapuro series. Also I loved Kuru Kuru Kururin on the GBA... I would love to find something like this modernized.
