About US

SL Kart Sport Organization (SLO) was founded by Yamaha Motor Co., Ltd. and Japan Kart Land Association in 2006. The precursor of SLO, SL Kart Club (SLKC) was founded by Yamaha Motor Co., Ltd. in 1974 and is the largest kart club in Japan. “SL” stands for “Sports and Leisure”. As its name suggests we hope people to have an easy and fun feeling about kart racing. Our aim is to organize fair, safe and affordable kart races by using one-make-based kart machines.

The top rankers of all the local SL kart race series aim to make the special event, the national SL kart race championship, truly to decide the Japan’s number one SL kart driver. The event has been held since 1977 and the names of Formula 1 drivers and many of the top drivers in the national and international race categories can be found in its winners list. This fact is a testimony to the SL kart races’ important role as a car racing initiator of which roles include teaching sporting regulations and race track manners, as well as being the first step in karting.

Setting the sporting regulations is not the only service of SLO, issuing and administrating the SL membership cards, fostering the young kart drivers, developing and promoting karting, educating the sport instructors and arranging tie-up with other kart races in the Asian countries are also our tasks. SLO always aspires to a better environment for kart racing.
