The Shikkake school (尻懸派) stands among the five great Yamato traditions (Yamato goha) that flourished in the shadow of Nara's powerful temples during the late Kamakura period. While traditionally attributed to Norihiro as founder, Norinaga (則長) is regarded as the de facto progenitor, documented through extant tantō bearing inscriptions of his age: forty-eight in Bunpō 3 (1319) and sixty-nine in Ryakuō 3 (1340). These datings place his birth in Bun'ei 9 (1272), establishing him as a contemporary of the school's early development. Learn more →
