Sai Koso

• Japanese/Chinese: 蔡 光祖 (Sai Kôso / Cài Guāngzǔ)

Sai Kôso was a Ryukyuan scholar-aristocrat who served as instructor to the musicians attached to two Ryukyuan embassies to Edo, in 1747 and 1751 (the missions each took place the following year). In 1747, he performed this task alongside Tei Ryôsai; in 1751, he oversaw the instruction in Chinese songs. In between these two appointments, he traveled to Fuzhou for a brief time in 1748.
