After being given an overview of those techniques and vowing to create a style of his own, Yoichizaemon travelled throughout Japan, to test his skills against other martial artists.

Instead, he continued training in ascetic practices, and meditated nightly, even going so far as to go on long retreats to secluded holy sites deep in the mountains.

Yoichizaemon continued training and travelling throughout his life, and at age 67 retired to pass the Suiō-ryū to his son, Mima Yohachirō Kagenaga.

The founder's son Yohachirō succeeded his father to become the 2nd head of the tradition and the lineage has continued unbroken to the present day.

These licenses act as recognition from the sōke that the practitioner has demonstrated a physical and mental progression in the tradition and later that they have his permission to transmit the teachings of the ryu.

In this oath the future member swears not to teach or demonstrate Suiō-ryū without the permission of the sōke to preserve the school's integrity.

Later, the fight choreographer of the second series of the TV show, featuring Yorozuya Kinnosuke, visited the Hekiunkan and impressed with the movements of the tradition spent some time learning the kata of the school.
