Frequently Asked Questions

What is Jujutsu?

Jujutsu is a Japanese martial art that focuses on unarmed combat against armed and unarmed opponents. Created by the samurai class of feudal Japan, the art was created as a means of incapacitating an opponent quickly and efficiently.

What is the difference between Jujitsu / Jujutsu / Jiu Jitsu?

Other than the romaji spelling, there is no difference between these words. They are all accepted English spellings of the same Japanese word, 柔術.​ Classical or koryu schools tend to use "jutsu", whereas many modern or gendai schools will use "jitsu". You will note that Daito Ryu, being a much older art utilizes "jutsu" and Danzan Ryu, being a more modern art uses "jitsu". Brazilian adaptations almost exclusively use "jiu jitsu".

What is the difference between Danzan Ryu and Daito Ryu?

Simply stated, Danzan Ryu is a gendai or modern system, whereas Daito Ryu is a koryu or classical system. Danzan Ryu was created in the 1920's in Hawai'i, blending elements of several classical jujutsu schools with several other martial traditions.
