Japanese Tendai 天台 monk; lifedates and biographical details unrecorded. DILA Authority A001603. Resident at Rìyù Zhāngfǔ 日域張府 (Japanese location, possibly the Tokugawa-period domain of Owari). Provided the huì 會 (“collation”) editorial work on the canonical recension of Míngkuàng 明曠’s Jīngāngbēi lùn sījì (KR6d0176, X56n0932) — the Tang-period subcommentary on Zhànrán’s Jīngāngbēi. The work survived through Japanese Tendai library transmission, from which it was eventually reprinted in the Manji-zoku canonical apparatus.
Note: distinct from at least four other monks named Biàncái 辯才 in DILA, including the Tang-period Biàncái of Cháng’ān (DILA A001602, 724–779; Néngjué dàshī 能覺大師), the Five-Dynasties Biàncái of Chóngfúsì in Tàiyuán (a disciple of Xīchén 息塵), and several others.
