Dàozhōng 道忠 (Japanese: Mujaku Dōchū 無著道忠)
The single most important Japanese Tokugawa-era Rinzai-Zen philological scholar. Hào Mujaku 無著 (“No-Attachment”); also Shōhyōdō 照冰堂 (“Illuminating-Ice Hall”) and Hōutō 葆雨堂 (“Protecting-Rain Hall”). Active at the Rinzai monastery Shōkoku-ji 相國寺 in Kyoto. Lifedates 1653–1744/5 (age 92 at death).
Dōchū produced an enormous philological-reference corpus on the classical Chinese Chán tradition, including:
- Zenrin shōkisen 禪林象器箋 — a monumental encyclopedic dictionary of Chán monastic terminology, remaining a standard reference work in modern Zen studies.
- Multiple yǔlù indexes, textual annotations, and philological studies.
- The Gǔ zūn sù yǔlù mùlù 古尊宿語錄目錄 KR6q0260 — his table-of-contents for the classical Sòng Gǔ zūn sù yǔlù, preserved in the Kanripo corpus.
Dōchū represents the apex of the Tokugawa-era Japanese Zen philological tradition, which combined meticulous Chinese-language scholarship with Zen monastic training to produce reference-works that both preserved the Chinese Chán heritage and made it accessible to Japanese practitioners.
