What is Danzan Ryu Jujitsu?

     Danzan Ryu jujitsu (or “Sandalwood Mountain System”) is a relatively modern form of jujitsu that was created by Seishiro Okazaki in Hawaii, circa 1900’s, which comprises techniques from a wide variety of martial arts, including multiple styles of traditional Japanese jujitsu (“koryu” jujitsu), Judo, Hawaiian Lua (a Hawaiian bone breaking art), Western Boxing, Sumo wrestling, and Filipino knife fighting, amongst others.  Okazaki traveled Japan extensively and trained with many martial arts instructors throughout his time.  With such a large range of styles and experiences to draw from, it is hardly surprising that the end result saw a system of Jujitsu that offered techniques for practically any possible situation or scenario.

     Okazaki, in an attempt to add some order to this large array of techniques, created a number of “boards”, which address specific facets of Jujitsu.  A very general overview of Danzan Ryu’s boards are as follows:
Yawara (20 Hand Arts)-

The practice of using the arms and hands as a means of escaping holds and applying joint locks to an attacker.

Nage (20 Throwing Arts) -

The practice of using leverage and off-balancing to throw an attacker to the ground.

Shime (25 Choking and Constriction Arts)-

The practice of restraining or incapacitating an attacker by using various grappling techniques such as chokes, strangles, arm locks, leg locks, and pinning techniques.

Goshin Jitsu (35 Additional Self Defense Arts)-

The first board to bring together the techniques of boards 1-3.

Oku (25 Advanced Arts)-

The Oku board brings together techniques from the previous four boards and focuses on seamless transitions and increased intensity.  This is generally when a student begins their path to black belt level.

Shinnin (35 Black Belt Arts)-

This is an advanced level board practiced by black belts, which encompasses all of the previous boards, but is performed with increased intensity and a high level of skill.

     As previously noted, this is an extremely simplified version of Danzan Ryu’s offerings.  The system also contains boards that are dedicated to knife and gun defense, striking, and a comprehensive system of restorative massage.

     Classes are taught by Professor Tom Hill, 6th dan in Danzan Ryu Jujitsu, by way of the American Judo & Jujitsu Federation, the largest Danzan Ryu Jujitsu organization in existence.  Professor Hill possesses over 35 years of experience in Danzan Ryu, in addition to other arts, and is one of the most well-respected instructors of the art.  To learn more about Tom Hill, please visit his biography.
