Vib Ribbon - Pretty good rhythm game
Gamera 2000 - Action game that plays just like the Panzer Dragoon games.
Wizardry Llylgamyn Saga - A collection of the first three Wizardry Games. I'm assuming you said no RPGs because of the language barrier, but this game has an option to change most of the Japanese text into English.
Wizardry New Age of Llylgamyn - Includes the fourth and fifth Wizardry games. Has the same English language option as Llylgamyn Saga (although there is an arrange version for 4 that is Japanese only).
Simple 1500 Series Vol. 94 The Cameraman - Port of the PC Engine game Gekisha Boy. Action game where you take pictures of strange things that happen around town.
Silhouette Mirage - Yes, this was released in the US, but a lot of people prefer the Japanese version because of the changes Working Designs made to it (your weapon power drains as you use it, power ups cost more, enemies do more damage).
Gunner's Heaven - Action game that's similar to Gunstar Heroes.
Panzer Bandit - I've never played it, but I hear it plays like Guardian Heroes.
Tobal 2 - 3D fighter that I'm told is pretty good (I'm not really into 3D fighters)
Dance Dance Revolution Series - If you like the DDR series, try the Japanese versions. The Japanese 3rd and 5th mixes are my favorites.
Ore No Ryouri - Very good fast paced cooking game.
I'll list more as I think of them.
