Harbor Circuit Indoor Karting provides a premier indoor go-kart racing experience to thousands of racers living and traveling through Japan every year. From professional racers to novices out to try something new, Harbor Circuit prides themselves on offering a fast-paced thrill ride that is approachable for all.
Harbor circuit prides itself on maintaining the absolute best karts, the safest barriers, highly-trained and professional staff and the most advanced timing systems – all in order to provide you with the ultimate driving experience.
There is no speed limit! The karts are fast enough to fly round Harbor Circuit’s pumping course layout, complete with its flying junction and tunnel. Sharp corners and twisty turns test even the most experienced drivers, yet it’s beginner-friendly too with numerous age groups and options for younger riders. A real-time ranking system allows groups of friends or family to compete against each other, and for individuals to race against their personal best times.
First-timers shouldn’t worry as all gear is available for rent and unlike the outdoor karting experiences you see around Tokyo, you don’t even need a driver’s license. All you need is a spark of curiosity and a desire for speed. Whether it’s your first time or you’re a regular racing pro, they make sure everyone is able to experience the freedom and the exhilaration of driving a high performance vehicle in a safe, comfortable and fun environment.
Anyone over 130cm tall (regardless of age) can throw the pedal to the metal in a Sodi RX-7, equipped with a Honda GX270 engine and manufactured by France’s premier kart-maker. Top speeds reach up to 50 km/h! Seats and pedals are adjustable for your comfort, so foreigners need not be too concerned about the fit. There is also a smaller kart tailored for those twelve and under. Mounted with the Honda GX160 engine, the ‘FunKid’ is chain-driven, meaning it runs quietly enough to keep little eardrums intact.
Enjoy the down time by drinking non-alcoholic beer and snacks. There are several tables with great window seating of the track so if you prefer to watch you can have just as much fun. There is no liquor served as racers are not permitted to drive after drinking.
