Stephan Yamamoto delved into the martial arts (Budo) during his younger days. His passion lead him to Japan, where he studied Karate, Kendo, Iaido and Sumo in Kyoto, Tokyo and Okayama. The most important training he recieved was at the Shushukan under Sugimori Kichinosuke and in Iaido at the Kenshinkan dojo. With his expertise in the martial arts comes hands-on experience in different forms of Asian manual therapy. Today he looks back on almost 30 years of experience as a martial arts teacher.
He dedicated his life to conveying his experiences and has taught on countless seminars in Germany since then. After different stops he has been teaching Karate and Iaido in Leimen and Heidelberg since 2016. He holds several ranks in the martial arts, underwent trainer courses with the DOSB, and joined executive comittees in Germany and Japan.
He also researched on the religious reception of the martial arts between 2013 and 2017 at the Institute for Religious Studies, University of Heidelberg, and became a member of the Bunbu Research Community. During that time he conducted several projects, such as „Shushukan Budo“ with Rouven Haberkorn, „Karadeera… bewegt Menschen“ with Andreas F. Albrecht and „simplyKarate“.
