Kakunyo 覺如 (clerical name Shūshō 宗昭, 1270–1351) — son of Kakue 覺惠 and great-grandson of 親鸞 Shinran — was the third monshu (abbot) of the Hongan-ji and the principal architect of the Hongan-ji branch’s claim to Shinshū primacy. His scholastic corpus — the Kakunyo go-bu-shō 覺如五部抄, the “Five Anthologies of Kakunyo” — consists of the Shitsuji-shō KR6t0373 (1326), Kuden-shō KR6t0374 (1331), Hongan-ji shōnin Shinran den-e KR6t0375 (1295, revised 1343), Hōon kōshiki KR6t0376 (1294), and the lost Shūishō. Together these constitute the early Hongan-ji theological canon.
Kakunyo’s political project — to establish the Hongan-ji as the legitimate Shinshū head temple against the rival Senju-ji 専修寺 and Bukkō-ji 佛光寺 branches — was largely accomplished in his lifetime through tireless polemic, including the disinheritance of his own eldest son Zonkaku 存覺 twice over doctrinal differences. He was succeeded by his second son Zen’nyo 善如. The DILA authority id is A001238.
