This antique Japanese Katana is attributed to the swordsmith Hizen Kunihiro, active during the early Edo period (1624-1661) in Hizen province. Kunihiro was known for producing blades with Konuka Hada, a smooth steel surface characteristic of Hizen swordsmiths who utilized western carbon steel. The blade comes with an NBTHK Hozon Certificate, confirming its authenticity and artistic value, and is accompanied by a full koshirae and shirasaya.

The Hizen Tadayoshi school began with a single domain commission. In Keicho 1 (1596) the Nabeshima of Hizen ordered Hashimoto Shinzaemon, the smith who would sign Tadayoshi, up to Kyoto with the carver Munenaga; there he entered the gate of Umetada Myoju and studied forging while Munenaga learned the chisel. The two returned to the province in Keicho 3 (1598), and Tadayoshi settled in the castle town below Saga, where under the domain's patronage the line grew into the dominant sword-making house of Kyushu.
