Treatise on Childbirth (Japanese: Sanron) by 賀川玄悅 (Kagawa Gen’etsu / Hèchuān Xuányuè, 1700–1777)
About the work
The foundational treatise of Edo-period Japanese obstetrics, written by Kagawa Gen’etsu 賀川玄悅 (1700–1777) and published in 1765 (Meiwa 2, Mínghé 2 in Sino-Japanese reading), with an appendix of forty-eight clinical case-records (zǐxuánzǐ zhìyàn sìshíbā zé 子玄子治驗四十八則) compiled by his disciple 山脅東門 Yamawaki Tōmon. The work breaks with the Chinese obstetrical tradition in three foundational respects: (i) the rejection of the prenatal abdominal-binding (zhèndài 鎮帶) and the labour-chair (chǎnyǐ 產椅) as harmful Chinese customs; (ii) the introduction of obstetrical manual manipulation (huíshēngshù 回生術, gōubāoshù 鉤胞術) for malpresentation and intrauterine fetal death; (iii) the use of pulse-and-abdominal-palpation diagnosis to determine fetal viability before intervention.
Abstract
Composed and printed in 1765 (Meiwa 2). The “Sino-Japanese reading” of the title preserves the Chinese characters but the work is a fully Japanese composition (in kanbun literary Chinese, the standard medium of Tokugawa scholarly medicine). Kagawa explicitly identifies his own school as a non-Chinese-derived (bù běn gǔ rén, “not based on the ancients”) tradition — Shibata Kunihiko’s preface to the Sǎn lùn yì states this directly: “the master’s learning had no transmitted teacher and was not rooted in the ancients” (學無所師承又不本古人). The author is identified throughout the text as Zǐxuánzǐ 子玄子 (“Master Zǐxuán”), Kagawa’s literary studio-name.
The 48-case appendix (Zǐxuánzǐ zhìyàn) provides extraordinarily detailed clinical-history records covering the full range of Kagawa-school obstetrical practice: malpresentations (transverse, breech, footling, brow-presentation, shoulder-dystocia, twins, pseudocyesis); the manual intervention techniques; the manual extraction of dead fetuses; emergency cases of post-partum xuèbēng (haemorrhage); and several cases of mistaken pregnancy / pseudocyesis correctly identified by Kagawa’s abdominal-palpation method. The case-style — including the patient’s social position, the date, and the physical findings — is notably modern in tone.
The work’s principal Chinese-tradition target is the 1715 Dáshēng biān 達生編 (KR3ei055), whose passive-quietism Kagawa explicitly rejects in case #16, #41, and elsewhere. The work was deeply influential in subsequent Japanese obstetrics; 片倉元周 Katakura Kakuryō’s Sǎnkē fāméng 產科發蒙 (KR3ei065, 1799) is part of the same Kagawa-school lineage.
The catalog meta gives Kagawa Gen’etsu but no dynasty marker (the hxwd recension treats Japanese works under the Qīng dynasty by default; the actual dynastic context is Edo-period Japan, contemporary with the late-Qiánlóng reign). Composition window precisely 1765, the date of first printing.

Other points of interest
The historical relationship of the Sǎn lùn to the contemporary Chinese obstetrical literature is one of the few clear cases of early-modern East-Asian medical exchange in the reverse direction: where Chinese obstetrical practices were not adopted but explicitly rejected by a Japanese practitioner who developed an alternative empirical system. The work survives in the Hǎiwài huíguī series precisely because the late-Qīng Chinese-medicine scholars who curated that series came to recognise Kagawa’s achievements.
