Features: This piece is a well-known sword attributed to the famed Den Go Yoshihiro of Etchu Province and is a former heirloom of the Date family.

The polish is of the highest quality, preserving the shinogiji in its original state to highlight the jigane of the Kamakura period.
Around the habaki area, a decorative polish has been applied to allow clear viewing of the distinctive Kamakura-period jigane.
If a bohi (groove) had been present, this feature might not have been as visible.
Originally a Date family heirloom, this sword has been regarded as a famous piece since ancient times.
It features inscriptions by both Kanzan Sensei and Tanobe Sensei.
Although the blade previously showed some cloudiness, it has now been polished to an excellent finish by polisher Saito Tsukasa.
