Takayuki Kubota

He held the title of sōke (grandmaster) for his development of the Gosoku-ryū, and was the founder and president of the International Karate Association.

[2] Kubota was a self-defense instructor for the Tokyo Police department in the 1950s, where he was noted for his expertise in practical karate.

In 1939, at the age of four, Kubota began studying martial arts under the direction of his father, who was a master of jujitsu and jukendo.

They were teaching local people with basics in the martial art of te; there was no name "karate" at that time in Okinawa.

While in a queue for food, however, Kubota helped the police to capture some criminals using his skill in taiho jutsu (arresting technique).

Until he earned enough money for classes, Kubota watched techniques at one of the top karate schools from outside at night.

He tested his martial arts skills by working as an agent in dangerous districts of Tokyo and being used as a one-man riot control by police.

[citation needed] From 1950–1959, he was an instructor for the US Army, Air Force, and Marines in kendo, karate, judo, and giyokute-jitsu.

Through 1964, Kubota taught self-defense to other government personnel, including the CIA agents at the US military bases throughout Japan.
