Restoration therapy has been practiced in Japan for more than 1,500 years and has proven successful in the treatment of migraine headaches, nervous tension, general fatigue, and muscular aches and pains. Professor Seishiro Okazaki was the foremost exponent of restoration therapy in America. He founded the Kodenkan Dojo, Ju-Jitsu School, and Nikko Restoration Sanatorium in Honolulu in 1929.

The therapy is a combination of amma, acupressure, shiatsu, chiropractic, osteopathy, and herbal medicines. Restoration therapy is divided into four age groups, and to be a successful practitioner of restoration therapy, a thorough knowledge of anatomy, physiology, pathology, dietetics, psychology, and herbal medicines is imperative.
