By one account he was a pupil of Tsunahiro of Sōshū, and it is said that Yagyū Tajima-no-kami Munenori — the celebrated swordsman and sword instructor to the Tokugawa shōgun — favored Hiroyoshi's blades. The Hiroyoshi style recalls the late Sōshū and late Bizen traditions, and is known for work of real force and presence. In August 2025 the NBTHK certified this blade as an authentic work of Hiroyoshi and issued its Hozon Tōken paper.\u003c\/p\u003e\n\n\u003ch3\u003eThe koshirae\u003c\/h3\u003e\n\u003cp\u003eThe sword comes in a fully lacquered \u003cem\u003eaikuchi koshirae\u003c\/em\u003e (a hilt-and-scabbard mounting without a tsuba), carrying the unmistakable air of a samurai household.
