Hohan Soken was born in Okinawa in 1889, the Great Grandson of Soken "Bushi" Matsumura. Soken's uncle, Nabe Matsumura, "Bushi's" Grandson, was one of the top karate masters at the time. Nabe offered to tutor Soken in Bushido, "the way of the warrior." Soken began training with Nabe Matsumura at age 13.
When Hohan Soken was 23, his sensei told him that he was ready to learn "real" karate. Hohan Soken was finally ready to learn the ancient secret of Hakutsuru.
Yabiku Hanshi and Chandler Kyoshi were students of Soken Hanshi.
O'Sensei Hohan Soken passed away in November of 1982 at the age of 93.
