San, Ni, Ichi… Hajime! Grab your running shoes and your cyclist repellent as the Nippon Marathon is here.


Enter the only marathon that simulates Japan while stimulating the senses - a raucous ragdoll party multiplayer game where just about anything can happen. Jump over barrels, swerve sweeping monks, side-step steamy monkeys, not to mention those naughty Shiba Inu! Don’t forget to pick up fruit along the way to hurl at your friends.


Choose from a cast of crazy characters including lobster-man J DARWIN, sea-life fanatic Elizabeth Nishibori, Zenbei the 'Old Uncle Sailor' and the furry faced Snuguru Maestro. Plus, unlock loads more.


  • Competitive Couch Multiplayer - challenge your friends to the only marathon worth entering. 

  • No previous running experience is required; perfect for both your athletic and couch-dwelling friends to enjoy.

  • Feel the ferocious fury of the AI - Solo Play is supported.

  • Be prepared for physics madness as you dodge, duck, dip and dive to avoid the crazy obstacles the Nippon Marathon will quite literally throw your way.

  • There’s a wide variety of characters to choose from, including a character with the head of a dog, and not just any dog, our dog!

  • Become acquainted with Wedy Jones, self-proclaimed NNBC's Reporter of the Year, who is guaranteed to keep you on your toes whilst she speed interviews you mid-race.

  • Meet a range of supporting characters in Story Mode, whilst uncovering the dark truth surrounding the Nippon Marathon.

  • Keep your pennies in your wallet where they belong as you can earn Yen during races to spend on unlocking extra characters and modes.

  • No need to pack your bags and fly to Japan, as you can see all the famous sights here! It's also a perfect warm up for the Tokyo Olympics.

  • The marathon is four player, however up to eight players are supported in Party Game modes in a pass-the-pad format.

  • Always wanted to grab a shopping cart and go bowling? Now you can with "Go-Go-Trolley Bowling", show your friends who's the true "King-Pin".

  • Don't be the "L.O.B.S.T.E.R." of the group by falling at the first hurdle in the Ninja Warrior/Takeshi's Castle/MXC inspired obstacle course. Jack Cactus won't be impressed.

  • An awesome Original Soundtrack composed by Independent artists featuring Naruto Shippuden Theme Vocalist, Diana Garnet.! OMG!
