Odai Yōdō 尾臺榕堂 (zì Shichō 士超, hào Yōdō 榕堂, 1799–1870), Edo-period Japanese physician, native of Echigo 北越 (modern Niigata Prefecture); originally surnamed Kosugi 小杉. Came to Edo in his youth and studied medicine under Odai Sengaku 尾臺淺岳, succeeding to the Odai house by his teacher’s command. Studied Confucian philology under the Kameda Hōsai 龜田鵬齋 / Bōsai school, and clinical medicine through the Yoshimasu Tōdō kohōha 古方派 lineage via Mine 岑少翁 / Mine Shōō. One of the principal mid-nineteenth-century Edo kohōha physicians; founder of the Edo Odai house’s practice. Author of the Lèijùfāng guǎngyì 類聚方廣義 (1856) — a critical expansion of 吉益東洞’s Lèijùfāng — and the Yī yú 醫餘 (KR3eq051, 1862, Zhōu–Hàn medical-philological compilation), among other clinical and textual works. The catalog meta form 尾台逸士超 preserves an idiosyncratic transliteration of his name and zì; the standard Japanese form is Odai Yōdō. Cataloged under 江戶 (Edo) rather than the catalog’s 清.
