Features:Naotane was born around Ansei 7 (1778) in Uzen-Yamagata. He was known as Shoji Minohyoe and became a student of Suishinshi Masahide. Later, he served under Lord Akimoto along with Masahide. Around Bunsei 4 (1821), he received the title of Chikuzen Daijo, and in Kaei 1 (1848), he was promoted to Mino-no-suke. His works are diverse, initially resembling his master’s large-wave midare (Ōtōran-midare) pattern during the early Bunka period. By the Tenpō era, he skillfully incorporated the Yamato-den, Sōshū-den, Mino-den, and Yamashiro-den straight tempering (suguha) styles. Naotane is regarded as one of the representative master smiths of the Shinshinto period.

Aoi Art’s Comment:　This sword features a bo-hi, which extends into the nakago. The presence of a kaō (signature mark) above the groove suggests that the groove was carved at the time of manufacture. This piece is a magnificent and imposing work with a long blade length of 80 cm (31.50 in).
