Welcome to the American Jujitsu Institute!

About the American Jujitsu Institute

The American Jujitsu Institute, headquartered in Honolulu, Hawaii is a Non-Profit, 501(c)(3) Educational Institution which perpetuates the teachings of Henry S. Okazaki and Kodenkan/Danzan Ryu Jujitsu.

The founder of Kodenkan/Danzan Ryu Jujitsu, Henry Seishiro Okazaki, was instrumental in the formation of the AJI with the hope that it would carry his system of jujitsu to all persons interested in its study. This mission began in 1939 when the AJI was formed, continued through the development of an official charter in 1947, and remains our primary focus today.

We hope you enjoy our website. Aloha!
