Kenwa Mabuni
In 1959, after the death of Kokuba Kosei, his only son Kuniba Shōgō (Kosho) became the third Sōke of Motobu-ha Karate-do, and the 1st Sōke of Motobu-ha Shitō-ryū Karate-do, a new style that he created by blending Motobu's karate with Shitō-ryū, which he learned from Kenwa Mabuni himself, and other styles that he was taught by the great masters who visited Seishin-kan. Since he was only 29 years old, Teruo Hayashi was appointed as technical advisor and president of Seishin-kai from 1959 until 1970.
