Among the provincial lineages of the Hokurikudo, the Fujishima school took its name and its base from the village of Fujishima in Kaga province, where Tomoshige stands as founder and the name he set down passed through several generations from the close of the Nanbokucho period across the Muromachi and on into the early-modern Shinto era. The members place the chronological anchor with care: the earliest firmly dated work is a tanto of Oei 2 (1395), and the NBTHK finds nothing among the surviving blades that goes back earlier than Nanbokucho.
