Yoshukan Crest.

The Yoshukan Crest symbolizes the historical roots of both the Chito-Ryu and Yoshukai systems in Yoshukan Karate and incorporates both symbols into a new and unique Yoshukan Crest. The association has further created a two-tier crest (Red for Mudansha and Gold for Yudansha) that identifies students as members of our association dedicated to the practice of Yoshukan karate.
