Yūkan 融觀 (clerical name Daitsū 大通, 1649–1716), forty-sixth abbot of the Dainenbutsu-ji 大念佛寺 at Hirano in Settsu (Osaka), the head temple of the Yūzū-nenbutsu-shū 融通念佛宗. He is conventionally — and accurately — called the restorer of the Yūzū-nenbutsu school: when he became abbot, the school had nearly collapsed through 16th–17th-c. institutional decline; under his leadership the school was reconstituted, gained official Tokugawa recognition as a separate Pure Land sect in Genroku 2 / 1689, and acquired (in his Yūzū enmon-shō KR6t0391) the systematic doctrinal foundation it had previously lacked. His doctrinal writing fuses Pure Land practice with Kegon (Avataṃsaka) enkyō metaphysics — the school’s distinctive theoretical character. The DILA authority id is A001247. He died at the Dainenbutsu-ji in Shōtoku 6 / 1716 at age 68.
