Welcome to the Seiseikan Dojo in Tokyo. This is the Japan Honbu (Headquarters) of the Ryushin Shouchi Ryu organization. We practice at the SOGO Sports Center Martial Arts Hall in Hamacho Park.  Students who are fortunate enough to train at Seiseikan will have the guidance of our chief technician, Kunikazu Yahagi, as well as the added benefit of several high ranking instructors.  Training at Seiseikan is considered a unique privilege and visiting students (RSR members and non-members) are required to schedule an appointment with Yahagi Sensei prior to visiting.



Yahagi Kunikazu is the chief technician (shuseki shihan) of Ryushin Shouchi Ryu.  Yahagi was introduced to kendo by his uncle at the age of 10 and commenced his kendo training in elementary school. He also trained in Judo from the age of 12, an art in which he later went on to earn the rank of 2 DAN at the Kodokan. He would continue his martial studies through his formative years, and at the age of 30, he entered the NCR dojo (now the Nihon Zaidan Building) in Akasaka, Minato-ku, Tokyo, which was then under the authority of Kawabata Terutaka.

After nearly 30 years of diligent training under the tutelage of Kawabata, Yahagi was licensed by the International Martial Arts Federation (IMAF) as a Kobudo Hanshi 8 DAN and later succeeded in becoming a director for IMAF. This would mark the beginning of Yahagi’s international teaching career. In 2008 Yahagi became the second headmaster of the Ryushin Shouchi Ryu.

In addition to his Ryushin Shouchi Ryu training, Yahagi continues his studies in Kendo and currently holds the rank of Kyoshi 7 DAN from the All Japan Kendo Federation.
