AIKIDO SHOWA DOJO

Hideki Kamezawa joined Showa Dojo in 1998 and has served as Dojo Head since April 2025. Aikido has no competitions and is not a martial art in which practitioners are ranked by winning or losing, so beginners can take part in practice with confidence. We provide an environment where students can continue training at their own pace while improving both mind and body.
