Fukuchi Seiko began studying Goju-Ryu Karate under the direction of Higa Seiko, as a junior high school student. After graduating from high school he became a soldier and was station in China. During that time he was exposed to Chinese Kenpo, which he studied for the duration of his tour of duty. Upon his release from active duty he continued his training with Higa Seiko in Okinawa.

He was a diligent student of Higa Seiko and became assistant instructor at Higa Dojo. He opened his own Dojo, the Senbukan (intense school of budo). In 1961 he was awarded the title of Kyoshi and in 1975 he was posthumously given the title of Hanshi.

He was one of the most talented Goju-Ryu masters and it was a great loss to the Karate world that he passed away at such a young age.
