Danzan Ryu Jujutsu (also spelled jujitsu or jiu jitsu) was created in 1929 by Master Henry Seishiro Okazaki when he founded the Okazaki Restorative Healing Institute and the Kodenkan School of Judo in Honolulu, Hawaii. He taught his students Kodenkan Judo as well as Restorative Massage. Four of his students moved to the U.S. mainland and founded the American Judo & Jujitsu Federation (AJJF), of which Wasenshi Kan is a member school. The lineage of Wasenshi Kan traces to two of those founders: Professor Ray Law and Professor Bud Estes.

Danzan Ryu Jujutsu focuses on techniques of joint locking, throwing, and grappling. Striking and kicking techniques are also taught, but they are not the primary emphasis. Rolling and falling techniques are integral to the study of jujutsu, so that the throwing techniques may be practiced safely. This may be one of the most practical applications of jujutsu for most people. Students who wish to focus primarily on learning how to roll and fall are welcome at Wasenshi Kan. Learning how to more effectively move your body, through tumbling techniques as well as throwing techniques, is one of the most rewarding experiences for many students!

Competition is important as a training tool for all students, but it is not the primary focus.  The development of effective self-defense, a healthy body and mind, continued personal growth and a desire to serve the community are the hallmarks of a successful student.
