Yoichizaemon continued training and travelling throughout his life, and at age 67 retired to pass the Suiō-ryū to his son, Mima Yohachirō Kagenaga. To the core techniques established by the founder, Yohachirō added the ten basic "Goin" and "Goyō" forms, which serve to establish strong basic technique. The 9th sōke Fukuhara Shinzaemon Kagenori created Masaki-ryū Fukuhara-ha Kusarigamajutsu, in part based on the Masaki-ryū of Manrikigusari, which has been handed down ever since as a separate tradition to each headmaster of the Suiō-ryū Iai Kenpō. The tradition of oral transmission of techniques continues to the present day, in the person of the 15th "sōke" of Suiō-ryū Iai Kenpō, Katsuse Yoshimitsu Kagehiro (also iaidō kyōshi 7. dan, kendo kyōshi 7. dan, jōdō renshi 6. dan). The headquarters of the tradition, the Hekiunkan ("Hall of Blue Clouds"), is located at Shizuoka City, Shizuoka prefecture, Japan.
