Zach started studying Toyama ryu battodo in 2011 at Byakkokan Dojo, where he still trains. He established the Brooklyn Battodo study group in 2016 as an extension of Byakkokan. Battodo is basically the same thing as iaido: swordsmanship that starts from the draw. Toyama ryu differs from most iaido schools in that our techniques are all done standing (no kneeling). Core principles include precise, strong, efficient technique; good posture; composure amid intensity; and controlling distance and timing when fighting against an opponent. We spar—and cut—to test and hone our skills. Zach strongly believes in teaching what he knows well and continually exploring what he doesn’t know. Sometimes that means the answer to a student’s question is “I don’t know” followed by developing an understanding through intense training. Zach also holds nidan in aikido and finds that studying sword has dramatically enhanced his aikido practice.



We offer 25+ classes per week. Founded 1981. Brooklyn's largest aikido dojo.

Head instructor Hal Lehrman is a 7th dan and Shihan (master teacher).
