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 Mitsuo 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.

  • All races, ethnicities, national origins, immigration/citizenship statuses, primary languages — all are welcome here. Negative attitude toward any of these categories is cause for ejection.

  • Sexual orientation and gender identity are irrelevant to our training. We do not tolerate any form of sexual harassment or misconduct. We also do not denigrate students for being “feminine” or “masculine”. We have men’s and women’s changing rooms, each with a shower, and we encourage students to change in whichever most closely reflects their identity. If that doesn’t work for you, we will work with you to make a plan to ensure that you are comfortable coming to train at the dojo. We are also a pronoun-savvy dojo.

  • The most visible aspect of what we do is physical. That said, in our home dojo in Japan you can meet a blind student who practices Tameshigiri (test cutting) and a student who has lost the use of his left hand but has won medals in gekken (sparring). We also know someone who practices from a wheelchair and another student who couldn’t lift his arms over his head when he started training. So if you have a sincere desire to learn, we will meet you where you are. Developing the strength and flexibility you need for proper movement is part of the curriculum. This training is about uncovering the best in each of us; we are all working on ourselves, and we do that work together.

  • A lot of martial arts schools would rather have your dues than have you on the mat, but we take the opposite view. We don't want anyone’s financial worries to come between them and their training. Please let us know if a scholarship or sliding scale dues would make the difference between you training and not. Most people choose to purchase their own uniforms and other equipment but we have some loaners and donated materials available.

  • Religion is irrelevant to our training, unless you have a strenuous objection to the ritual involved in our reiho, in which case we should have a respectful conversation about it and figure out the best way forward.

  • Although we teach a martial art, we recognize that students may have past experiences that change their view of physical contact. We generally believe that while being able to make physical adjustments to students can accelerate their progress, it is not required; and in fact one of the lessons of the COVID pandemic is how to adapt to being able to teach without contact. Relatedly, we can tailor our gekken (sparring) practice to the needs of each student.

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).
