Koyama Dojo is the Honbu Dojo for Hakko Denshin Ryu JuJutsu (HDRJJ) in North America, practicing the traditions of Shodai Soke Lamonica. With over 25 years of teaching experience, the instructors deliver the traditional Shihan/Deshi style of one-on-one instruction. The dojo teaches Hakko Denshin Ryu JuJutsu, an ancient martial art that is also an incredibly effective self-defense system. It teaches students how to use natural movements with very little effort to defeat much larger attackers. The classes are designed to build confidence and skill very quickly. Hakko Denshin Ryu Jujutsu is descended from ancient Genji Clan Samurai techniques.
