Welcome to the official United States Yoseikan Budo Association (USYBA) web site.
The USYBA is a national organization with authority to teach, promote, and govern the practice of Yoseikan Budo throughout the United States. It was established by the authority of Master Minoru Mochizuki, founder of Yoseikan Budo. We are affiliated with Gyokushin Ryu Aikido under the direction of Terumi Washizu Sensei and the World Yoseikan Federation.
The USYBA organizes clinics, assemblies, and an annual training camp (YoseiCamp), where students from around the globe meet for intensive physical and mental training in the techniques and principles of Yoseikan Budo and Gyokushin Ryu Aikido.
