Kosei Kokuba was the youngest son of a branch of the Okinawan royal family, the Sho Shi Family and was born in 1901, in the Kokuba Village or what is now Naha City,
During the difficult years of World War II, many of the Okinwan Karate men left their homeland. Most of them came to Osaka and visited the home of their old friend Kokuba-sensei. In return for room and board, these men often taught at the Seishin Kan Dojo and gave private lessons to Kokuba-sensei’s young son, Kosho. The Seishin Kan Dojo became a famous meeting place for Budo men in Osaka and the training was with the men who are the founders of Karate-do as it is taught in the world today.
