Play Janshirou Online
Tiny sumo wrestlers slide around like they're on ice, flailing wildly as you try to shove the other guy out of the ring—it's way more tense than it looks. The crowd goes nuts over every near-fall, and you'll absolutely yell at your friend when they trick you into charging off the edge.

Janshirou was a Game Boy release from 1990, developed by Irem. It arrived during a period when the handheld was becoming a hub for arcade-style experiences, offering a condensed version of a familiar sport. The game doesn't try to reinvent the wheel; it just gives you a pocket-sized sumo ring to play in.
You control a small sumo wrestler, moving on a slippery surface as you attempt to push your opponent out of the circular ring or force them to touch the ground. The main objective is to win each match by outmaneuvering the other wrestler, either through direct shoves or by tricking them into overcommitting to a charge. Signature mechanics include a charge move that builds momentum but leaves you vulnerable if you miss, and a careful balance between aggressive pushing and defensive positioning. The pacing is quick, with matches often decided in seconds, and the difficulty ramps up noticeably as you face more aggressive AI opponents. It feels like a tense, physical shoving match where every slight miscalculation can send you flying.
