About Battodo

Battodo (抜刀道) literally means “the way of drawing the sword.”

Battodo is also a budo: a lifelong pursuit of self-improvement and shinshin-tōitsu (心身統一), the unification of mind and body.

Zentokan Dojo (前途館道場) is a 501(c)(3) non-profit school of the Japanese sword founded in 2016 by Zach Biesanz. The dojo began as an extension of the Byakkokan Dojo under the guidance of Sang Kim. Since that time, Zentokan has grown and operated continuously in its present home, sponsoring seminars on Toyama Ryu Battodo and other Japanese sword arts, as well as special classes in a variety of complementary disciplines. Michael Shane has been the chief instructor since 2022.

Zentokan is a member dojo of the Zen Nihon Toyama Ryu Iaido Renmei and the United States Federation of Battodo.


Hataya Mitsuo sensei

Toyama Ryu (戸山流) Battodo was created almost a century ago when Japan enlisted a group of master swordsmen, including Nakayama Hakudo sensei, to teach military officers how to use their katana effectively in combat. Using older classical styles of swordsmanship as a foundation, they created a school of swordsmanship rooted in both tradition and realism.

Our practice follows the curriculum created by Nakamura Taisaburo sensei and his student, Hataya Yoshitoki sensei.

The kata and techniques of Toyama Ryu are relatively few and unadorned. Designed to be effective under stress, they offer practitioners a laboratory for the development of truly spontaneous swordsmanship — a state of ultimate freedom and capability that Nakamura sensei called jiyu jizai ( 自由自在), which means freely free.

Everyone is Welcome

We believe that martial arts training should provide a welcoming environment for everyone. Anyone with a sincere desire to train has a home here regardless of who they are or where they come from. We encourage every dojo member to approach any one of the instructors in confidence anytime with questions, feedback, concerns, or requests for help.

Budo is a path for polishing the self, and demands a correct outlook in order for it to be meaningful. Practitioners must give careful consideration to the significance of their daily training, and adopt an attitude of humility and selfless service for the greater good.

Budo is a profound study undertaken with the aim of mastering one’s body and mind through scholarship and the warrior arts, and must be practiced with a spirit of humility.

The practitioner of swordsmanship must constantly seek self-improvement and train with the right mind, conscious always of the philosophy of the art of peace. This state is known as katsujinken (活人剣 / life-giving sword).
