Authentic Martial Arts Straight from Okinawa.

Palace Hand (Okinawan Ju-Jitsu)

Japanese Sword



Palace Hand is an old martial art rarely seen outside of Japan.


Unlike most commercially available martial arts, Palace Hand has not been turned into a sport, and remains focused on practical, straightforward self-protection skills. 


Palace Hand was designed as a battlefield and bodyguard art for the royal family on the island of Okinawa. It is specialized for enabling a person to handle a larger and stronger attacker and multiple attackers. 

More than just punching and kicking, Palace Hand is a martial art, philosophy and path for personal development and self-mastery.
