Born to a wealthy family who owned a large portion of land in the Fukushima countryside, with the easy accessibility of the family plot, Kumakubo was able to use some of it to build and develop the Ebisu Circuit.^[1]

Kumakubo also used the circuit to host numerous drifting events as well as various motorsport events. As the lead driver of Team Orange, as his car has always been orange, he started at the D1GP series in a Nissan Silvia, in 2005, whilst stumbling through the numerous rallying magazines in his office and considering that the Subaru Impreza was the car to have as many rear wheel drive cars were considered not suitable for drifting or in need of development to be considered suitable, also in a way to bring Impreza owners to his track, Kumakubo commissioned tuning company JUN Auto to build an Impreza WRX STI Impreza, significantly with a radiator on the rear passenger side.^[1]

The car debuted at the Odaiba round, unlike others who switched to newer models, his performance would pay off when he was runner up at the Silverstone exhibition round and for the 2006 season, he had beaten Ken Nomura by just 1 point. Midway through the 2007 D1 series Kumakubo switched from the Impreza to an Evo 9 (built also by JUN Auto) during round 5 at Ebisu.

He has also built a Mitsubishi Lancer Evolution X in the Team Orange livery which was shown at the Tokyo Auto Salon.

He also runs the Big X the invitation only outdoor show that combines drifting, FMX, supermoto, car stunts and other extreme sports featuring the experts from each field.

Big X's drifting squad is called DriftXtreme, which the well known drivers of the D1GP are invited to join including team mate Kazuhiro Tanaka and Naoto Suenaga.

Kumakubo competed in the European Drift Championship during the 2008 season alongside his Team Orange teammate Kazuhiro Tanaka in his Subaru Impreza WRX STI.^[2]
