KOKODO JUJUTSU

KoKoDo translates to "Imperial Light Way". It was founded by Shodai Soke Irie Yasuhiro and can trace our lineage to Sokaku Takeda of Daito Ryu Aikijujutsu.

JuJutsu can be translated as "Yielding art" It includes the concepts and philosophies of being soft, subtle as well as flexible. Jujutsu has its origins from ancient Japan, where it was referred to as Yawara. Its main function was as a secondary combat option for a samurai warrior when he was without weapons, and had to deal with armed and unarmed situations.
