On May 26, RPG Maker VX will get an expansion pack filled with items to turn Murasama: The Demon Blade into a RPG. The Japanese style material collection includes animated characters, portraits, monsters, tile sets, icons, window skins, and attack effects. All are based on Japanese mythology and you can see many of the tiles in this video.
The rest are on the sample site which shows ninja, oni, samurai, and raccoons. I, for one, welcome the upcoming reign of raccoon RPGs.
