Sensei Taku Nakasaka started Kyokushin Karate in his hometown, Sapporo, Japan in 1982.  He rapidly gained recognition throughout Sapporo Japan as a Kyokushin fighter, successively claiming several championship titles.  He then served as an assistant instructor of the I.K.O. Kyokushinkaikan Dojo in Sapporo, Japan.

His focus and drive lead him to United States at the age of 23.  From 1990, Sensei Taku Nakasaka trained vigorously under Sensei Jimmy Nishimura, former Branch Chief of Los Angeles.  Under  Sensei Jimmy Nishimura's vigilant leadership and guidance, Sensei Taku Nakasaka was  able to claim  one of the top positions among the nine fighters chosen to represent  the United States in the 6th World Open Karate Tournament in November 1995.  Sensei  Taku Nakasaka was  placed among the best  32 out of 168 world top fighters.

In 1996, he fulfilled his childhood dream of opening a dojo in the United States.  His first dojo followed by three subsequent dojos, opened in Los Angeles, California.  The other dojos are currently located in Torrance, Tustin, and North Valley.

Sensei Taku Nakasaka, in a joint effort with I.K.O. Kyokushinkaikan, hosts annual karate championship events in Los Angeles, California, bringing in the top fighters from the world.
