Born in Minato-ku, Tokyo. He displayed extremely early development in language and mathematical concepts and was lauded as a precocious genius, but apparently precocious was exactly what he was; his intelligence didn't progress thereafter, and he grew up to be a boy who couldn't take a hint.

He started playing the shamisen with a yearning for Eddy Van Halen, and recruited his younger friends from college, Pierre Ono and Tasuto Torami, to begin performing on the streets. There were a number of excellent ideas for the group name, but they settled on “Seshami Street Boys”, which has absolutely nothing to do with the educational children’s TV show. They continued heading in the wrong direction to that of comedy street performance.

They passed the first "Heaven Artist" audition––for selecting licensed street performers who are officially recognized by the Tokyo Metropolitan government. After that, because Ryo knows how to get a laugh, and can MC fully in English, though not very good at it, he's been considered useful, and has become a shamisen entertainer who travels not only in Japan but around the world, thus going completely off the rails. He also has participated in tournaments as a member of the Tsugaru shamisen quintet "Orand" with Takemi Hirohara and Hikari Shirafuji, in addition to Pierre Ono, participated in the band "Project Wago", produced the ondo band "Karakara", became a leader of shamisen and Japanese traditional folksong trio "Mitsuba", and became a PADI diving instructor––basically, a nonsensical career. Other than learning the shamisen under the late master Toyoaki Fukushi, but he hasn't really lived up to their names.
