We are pleased to announce the arrival of a piece by Bizen Osafune Skesada, certified as authentic by the Society for Preservation of Japanese Art Swords.

The sword is in excellent condition, with the entire blade sharpened and sound with no flaws, chips, or rust of any kind. It is estimated that the sword was originally around 79 cm in length, but was adjusted to its current length in later years. the name of the swordsmith was cut by Suriage.

Jigane is a very beautiful jihada with well-kneaded itame. Hamon is gunome mixed with choji, and the tops of some choji are sharp and have a pattern like a crab claw. This is called Kaninotsume, and this is a signature hamon of Sukesada. In the ha, yo can be seen.

The Nakago is engraved on the Sashiomote side with “Yokoyama kozuke daijo fuji...,” and the inscriptions after that are unknown because of the suriage, but they should have been engraved with "Yokoyama Kozuke Daijo Fujiwara Sukesada. On the Sashiura side, “Bizen Osafune” is engraved, and it is assumed that the inscription would have originally read “Bizen Osafune Junin,” or residents of Bizen Nagafune. Kozuke Daijo Sukesada, whose real name was Heimon, was the son of Shichibei Sukesada and revived sword making in Osafune, which had been severely damaged by flooding. He was the sixth generation, counting from Yosozaemon'nojo Sukesada, who flourished during the Warring States period, and was the greatest contributor to the prosperity of Bizen swords in the Shinto period, receiving the title of Kozuke Daijo in 1664, at the age of 32.

The Society for Preservation of Japanese Art Swords issued a certificate of authenticity for this work in February 2025, recognizing it as an authentic Kozuke Daijo Sukesada and as highly worthy of preservation for future generations. Now you have the chance to acquire a genuine piece of the Sukesada that embodies Bizen-den.
