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.
