San! Ni! Ichi! Hajime!!! Stretch your muscles and embark upon the ultimate marathon of Japan in a ...

Four-player madness!

You can’t spell Nippon Marathon without ‘P’, ‘A’, ‘R’, ‘T’ and *checks letters* ‘I’, we suppose… Solo play is supported, but grab up to four pads and enjoy the supreme silliness of gaming’s greatest marathon.

See all of Japan!

Cross the entirety of the land of Nippon in a series of creative levels spanning busy city streets, village lanes, bustling markets, mountaintop shrines and even unsafe sake distilleries!

Wacky characters!

Go toe-to-toe with some of the coolest racers who ever did, er… race! Lobster-man J DARWIN, unicorn onesie-wearing Elizabeth Nishibori, school uniform fan Zenbei “Xen Bae” and the completely normal Snuguru Maestro are among the challengers vying for the podium!

Epic pratfalls!

Swinging poles! Giant face-slapping fish! Cyclists! Shiba Inu! Panes of glass! Traffic! False doors! Barrels! Rolling beams! Wobbly planks! Flying fruit! More Shiba Inu! Dodge and dive over the lot or suffer the painful and embarrassing consequences of physics-based collisions…

Tons of surprises!

You never know what will happen next in Nippon Marathon. Perhaps you’ll find time for an impromptu spot of slot machine fun? Maybe a news anchor will jetpack in to interview you on the racetrack? Heck, anything is possible…

Drop-in/drop-out play!

Need a bathroom break to brush pineapple juice off your onesie? Random pedestrian passing by your couch and wants to play? Whatever the cause, hop in and out for the ultimate, flexible party get-together!
