After studying for a time in Fuzhou in 1768, Ryô led lessons in Chinese dance for performers who were to go on a mission to Kagoshima in 1772; he returned to Fuzhou in 1785, and then in 1789 was appointed alongside Mô Shin'i, Ryô Shô, Rin Keshô, and Mô Chishi to help train musicians and dancers for the 1790 Ryukyuan embassy to Edo. He served in a similar position again in 1805.
