What we’re about


Aikido is a Japanese martial art now practiced internationally. Aikido literally means "the Way" (do) of "harmony" (ai) with "energy or nature (Ki)." It's not primarily a system of combat, but rather a means of self-cultivation and improvement. Aikido has no tournaments, competitions, contests, or "sparring." Instead, all aikido techniques are learned cooperatively at a pace commensurate with the abilities of each trainee.


Founded in the U.S. by Roderick Kobayashi Sensei, the objectives of Seidokan Aikido are to study the philosophy and the arts of aikido and further develop them to best suit the modern way of life. Seidokan follows the line of tradition which encourages ongoing refinement of the art to accommodate a modern way of life. Technique tends to utilize movements which are very small and economical. Manifesting the principles of oneness and "loving protection of all things" is the goal of Seidokan practice.


Seidokan Aikido of Tokyo was founded in 1995 as an official dojo of Seidokan Aikido. Our aim is to promote the understanding and application of aikido principles through regular practice in the dojo. Students can learn a modern style of aikido in an international environment. SENSEI

The class is taught in English and led by Chris Koprowski, who hails from Duluth, MN (USA). He has been living and working in Tokyo since 1993, and has been teaching Seidokan Aikido since 1994. He currently holds the rank of godan (5th degree black belt) and is a certified "shidoin" (instructor) in Seidokan Aikido.


Our dojo welcomes students of all levels--both men and women, Japanese and non-Japanese.

The first month of instruction is FREE. Afterwards, dojo membership fees are ¥1,000/month or ¥10,000/year. This covers instruction, exams, and dojo administration. In addition, the sports center charges a ¥320 facility fee each visit. Our classes are not officially registered with the sports center and take place when the facility is open to the public. This means sharing the dojo space with other groups.

Please wear loose fitting clothing that you can move around in. Later, a dogi (practice uniform) can be purchased and is recommended. We can provide a map to a budo supply store.

Promotional tests are conducted periodically and eligibility depends largely upon regularity of attendance, understanding of technique and aikido principles.

Sat classes are held 1:00pm-3:00pm at Higashi Itabashi Gymnasium. A 5-min walk from Shimura-sakaue station (Toei Mita line). Exit A1.
