This is a great opportunity to explore and practice the principles that make Kenjutsu and Aiki Jujutsu effective for modern protection and conflict resolution.

James Williams Sensei is the Kaicho of Nami Ryu Aiki Heiho. With over 50 years of martial experience, James’ love of samurai martial traditions came with his study of the Yanagi ryu of the Yoshida han under Don Angier Sensei and the martial traditions of the Kuroda han as taught by Kuroda Tetsuzan Sensei. James also studied Daito ryu Roppokai with Okamoto Seigo sensei. Nami ryu is based on the ancient armed and unarmed martial arts that were the exclusive secret of the Samurai nobility. Later these arts formed the basis of modern arts including Brazilian Jujitsu and Aikido.
