Kakujō 覺成 (fl. mid-to-late 12th c.) was a Japanese Shingon monk of the Hirosawa-ryū 廣澤流 transmission line associated with Ninnaji 仁和寺. He is to be distinguished from the contemporary Vinaya master Kakujō 覺盛 of Tōshōdai-ji (1194–1249, see KR6t0049–KR6t0050) — same pronunciation, different character. His Ninnaji-aligned ritual records were preserved through the editorial work of his contemporary Shukaku Shinnō 守覺親王 (1150–1202), and are extant primarily as the Hirosawa-ryū stratum within Shukaku’s KR6t0194 Zé chāo (Sawa-shō).
His lifedates and biographical particulars are not securely recoverable from extant records; the DILA Buddhist person authority records him under A001122.
Surviving work in the Kanripo corpus: KR6t0194 Zé chāo (10 fasc., with Shukaku Shinnō as editor).
