Seishiro "Henry" Okazaki :

A Japanese American healer, martial artist and founder of Danzan Ryu jujitsu. Born in Kakeda, Date County in Fukushima Prefecture, Japan, he immigrated to Hawaii in 1906. At the age of 16 he learned he had tuberculosis. Through hard training in the martial arts, Okazaki recovered completely and vowed to dedicate his life to propagating jujutsu and judo. From 1927 to 1928, Okazaki developed a complete, integrated martial arts system: Danzan Ryu Jujutsu. A synthesis of several older styles of jujutsu, Okazaki included in the system elements of his studies of Okinawan karate, Chinese kung-fu, Hawaiian Lua, Filipino knife fighting (escrima), boxing and wrestling, as well as traditional Japanese restorative massage and healing techniques (Seifukujutsu).

Gradually, Okazaki developed a system comprising courses for men, women, and children. In his system, he stressed the ancient system of philosophical and moral training within the martial and restorative arts. He is credited with being the first to teach the full jujutsu course to non-Asians. He also taught perhaps the first women's self-defense course in the country. This was in response to the number of women in Hawaii who were sexually assaulted by soldiers stationed there. For all his work in martial arts, he was best known for his healing arts.

Okazaki initially faced opposition within the Japanese-American community for teaching outsiders Japanese martial arts. This changed after World War II. Like tens of thousands of other Japanese-Americans, Okazaki was interned during the war. Unlike others, however, his home and property were not looted; his students guarded them during the war. Upon their release, Okazaki helped support others in the Japanese-American community. For this he ultimately gained their respect.
