Kagawa Genteki 賀川玄迪 (Sino-Japanese reading: Hèchuān Xuándí; original name Okamoto Kishi 岡本起 Zǐqǐ; zì Shikei / Zǐqǐ 子啟), 1739–1779, Edo-period Japanese physician. Adopted son-in-law and principal disciple of Kagawa Gen’etsu 賀川玄悅 (賀川玄悅), founder of the Kagawa school of obstetrics. Originally from the Okamoto 岡本 family; Gen’etsu, declining to pass his obstetrical technique to his own biological son, transferred the teaching to Okamoto Kishi, who was adopted into the Kagawa lineage and took the school-name Genteki.
Author of the Sǎn lùn yì 產論翼 (KR3ei066, 1775), the principal continuation and supplement to Gen’etsu’s Sǎn lùn of 1765. The work extends the Kagawa techniques in twenty new categories (按腹 abdominal palpation, 整胎 fetal positioning, 探宮 cervical examination, 救痙 eclampsia management, etc.), adds 32 illustrations of fetal presentations, and appends 28 detailed clinical case-records of Genteki’s own practice.
Honoured with stipendiary appointment by his domain in 1772; received imperial-domain summons to Edo in 1782 (Tenmei 2) — though Genteki had died three years earlier (1779), the appointment indicates the high reputation of the Kagawa-school techniques at the level of bakufu medical politics.
