Welcome to the official website for the Ryuhokan dojo and training group. We teach traditional Gojuryu Karate as passed down by Toyama Zenshu Hanshi and Ryueiryu Kobudo. Classes are held at Risner Gym on Kadena Air Force Base Okinawa. Visitors are welcome, however if you don't have access to the base please contact us so we can coordinate your visit. We are a proud member of the Okinawa Tenbukai established by Toyama Hanshi.
