About Aikido Tekkojuku

Aikido Tekkojuku is a traditional dojo devoted to advancing Aikido as a path of both martial and personal growth. We practice in the tradition of Mitsunari Kanai (8th dan, Shihan), himself a disciple of Morihei Ueshiba O-Sensei, the founder of Aikido. Kanai-Sensei’s Aikido emphasizes the unification of the body; the generation of dynamic power from the hip (koshi); and the connection between empty-handed movements and sword movements. At Tekkojuku, many of Kanai-Sensei’s most senior students continue to develop and teach his Aikido in his loving memory. Our name “Tekkojuku” is derived from tekko, a compound word of Kanai-Sensei’s invention (see The Meaning of Tekkojuku), and juku, meaning a school offering intensive education outside of school hours.

The following film contains rare footage of Kanai-Sensei.  It was made in 1970 by Sharon Mann, a long-time student and friend of Kanai Sensei. It was originally made as a project for an undergraduate film class. Sharon recently edited it and is releasing it publicly as a tribute to Kanai Sensei’s remarkable art and spirit.

Aikido Tekkojuku does not claim authorship of any content contained in this film. You may share this gem widely but you may not charge money to see it.  


As well as a martial art, aikido is a practice of personal and interpersonal development. Tekkojuku therefore promotes vigorous training alongside a values-driven and friendly dojo culture. We celebrate the diversity of our members; their achievements on and off the mat; and the friendships they forge with each other.


Tekkojuku offers an expansive and flexible training schedule, including weekday evening, and weekend morning classes. We have a spacious practice area as well as a comfortable observation area for visitors. Most importantly, we offer a vibrant community of instructors and practitioners.

Tekkojuku is conveniently located at the Reservoir Church, conveniently accessible from both the Davis Square Red Line T stop. For those traveling from Porter or Alewife, the #83 bus stops right in front of the Church. There is plenty of off-street parking. Please don’t hesitate to contact us to ask questions or plan a visit.
