YoseiKan is a new form of marital arts that incorporates techniques from other martial arts such as judo and jujitsu.

YoseiKan is a comprehensive Japanese martial art mixing elements of jujitsu, judo, karate, western boxing, and a variety of other martial arts styles. It has evolved over the years to incorporate a wider range of styles and increased emphasis on competition.

The goal of YoseiKan training is to create an environment that allows students to discover their own sense of the "truth" by studying a wide range of martial arts techniques and philosophies.

Standard competitions are comprised of three types of sparring: sude randori, emono randori, emono sude randori. There are very few prohibitions for these kinds of sparring competitions, but there are two sets of forbidden techniques.

The name YoseiKan is derived from three Japanese words: yo meaning teaching, sei meaning truth, and kan meaning place. YoseiKan was created by Minoru Mochizuki in 1931 as a composite martial art. Mochizuki studied under and assisted the founders of judo and akido, as well as being a student of karate and koryu budo. His experiences are reflected in the sport's eclectic style, which mixes aikido, jujitsu, judo, karate, and Tenshin Shoden Katori Shinto-ryu. In the 1970s his son, Hiroo Mochizuki, began introducing western elements like boxing, and an emphasis on competition. Hiroo is responsible for evolving the sport into what it is today.

Belt
Keikogi
Padded Weapons
Protective Equipment

During competitions, complete protective equipment is required to avoid injuries. There are also two techniques that are forbidden: kicks to the knees or joints, and head grabs or twist.

Practitioners of YoseiKan undergo rigorous training. Those wishing to gain teaching credentials had to participate in a considerable amount of cross training; this included gaining a minimum of black belt in judo, as well as training in aikido, karate and Katori Shinto Ryu. Mochizuki emphasized training in karate based striking, forms of joint manipulation, footwork, jointlock flow and counter form, paired swords form, defense against weapons, and multi-person attacks. Students also had daily free practice in single and multi-opponent sparring. These techniques were the core of the original curriculum.
