He studied Okugi, considered the very secret techniques. He eventually acquired six hundred and seventy five techniques and earned a third rank in Judo. Professor Okazaki eventually returned to Hawaii and formed an eclectic system which he called Danzan Ryu. This system included Judo, Jujitsu, Hawaiian Lua, Okinawan Karate, Chinese Kung-Fu, and American Wrestling. Breaking with tradition, Okazaki taught not only the Japanese, but any and all races.
