Play Osomatsu-kun - Hachamecha Gekijou (Japan) Online
Punch your way through absurdly chaotic stages as one of six identical troublemakers—ride giant rolling Darumas, smack your own brothers, and bounce off springboards like a '90s cartoon gone wild.

Game Overview
Osomatsu-kun - Hachamecha Gekijou is basically what happens when you take six identical troublemakers and throw them into a Sega Genesis game. It’s pure chaos—you’ll be jumping between weirdly colorful stages, punching random enemies (or your own brothers, because why not?), and occasionally riding a giant rolling Daruma like it’s totally normal.
The controls are simple, but the game doesn’t care about making sense. One second you’re fighting some goofy-looking thug, the next you’re getting launched across the screen by a springboard. The whole thing feels like a playable cartoon from the '90s, complete with exaggerated sound effects and that classic Japanese humor where everything’s just a little bit ridiculous.
If you’ve ever watched the anime, you’ll recognize the Matsuno brothers’ brand of nonsense right away. If not, well—expect a lot of yelling, slapstick, and pixelated mayhem. It’s not the deepest game, but it’s got charm to spare.
