Fujaku 普寂 (1707–1781) was an Edo-period (江戶時代) Japanese scholar-monk based at the Chōsen Ritsu-in 長泉律院 in Edo (now Tokyo). One of the most prolific and doctrinally wide-ranging eighteenth-century Tokugawa scholastics, he is known for a deliberately cross-school programme that combined training across Hossō 法相, Sanron 三論, Kegon 華嚴, Tendai 天台, and Vinaya 律 traditions, all interpreted from a foundational Pure Land 浄土 doctrinal standpoint.
His principal contribution to Yogācāra studies is the pair of Indian-Yogācāra commentaries preserved in the Taishō supplements:
- KR6n0021 Jōyuishikiron ryakusho 成唯識論略疏 (T2267, 6 fasc.) on the Chéng wéishí lùn (KR6n0016, T1585);
- KR6n0062 Shōdaijōronshaku ryakusho 攝大乘論釋略疏 (T2269, 5 fasc.) on Paramārtha’s Mahāyāna-saṃgraha commentary (KR6n0061, T1595).
He also authored B0184 Ken’yō shōbō fukko-shū 顯揚正法復古集 — a polemical work in the daijō hibussetsu-ron 大乗非仏説論 debate. The two Yogācāra ryakusho commentaries together established the canonical shape of Edo-period engagement with the Indian Yogācāra commentarial tradition, structured by characteristic ten-gate prolegomena (xuántán 懸譚) that incorporated Japanese transmission-history into the canonical apparatus.
