Wakataka Oozumo: Yume no Kyoudai TaiketsuSuper Famicom Japanese (NTSC-J) Games
This is pretty sweet - it's a sumo wrestling game that apparently is a dream match between two brothers that are also sumo wrestlers. You get a side view, kind of like Street Fighter II, and take to the sumo mat to try to win the match!
