Kunimitsu Takahashi was a Japanese professional motorcycle road racer, racing driver, and team manager. Nicknamed "Kuni-san", he is known as the "father of drifting".

Drifting is a driving technique where the driver intentionally oversteers, with loss of traction, while maintaining control and driving the car through the entirety of a corner or a turn. The technique causes the rear slip angle to exceed the front slip angle to such an extent that often the front wheels are pointing in the opposite direction to the turn. Drifting is traditionally performed using three methods: clutch kicking, weight transfer, and employing a handbrake turn. This sense of drift is not to be confused with the four wheel drift, a classic cornering technique established in Grand Prix and sports car racing.
