Koshi-mawari, the kernel of Aikido

References are made to a book written by Narita Shinjūrō – Kōrindō Aikidō. You will also find references to Hino’s Budō and to Senta Yamada, a Tomiki Aikidō pioneer. I made also references to Koryu-no-kata, compiled mostly by Hideo Ohba, Tomiki’s lifelong disciple.

An organic project

This project is a growing project and content will be added on a regular base. As long it is not finished, it will be not published online. You can ask a pdf-file via mail for your own research and training . (shobukai@tomiki-aikido.be). Please be so kind to introduce yourself when asking for a copy.
