This katana is signed by Yokoyama Sukekane, a prominent smith of the Shin-Shinto period from Bizen province. He proudly signed himself as the 58th generation descendant of Tomonari, the founder of the Bizen smithing tradition. The blade features a wide body, slightly thick kasane, and a tight ko-itame hada, with a hamon primarily composed of nioi-gachi choji midare, including koshigata-choji and kikka-choji patterns. It comes with an NBTHK Tokubetsu Hozon paper.

The Edo period (1615 to 1868)
For two and a half centuries of peace the sword was the warrior’s legal badge rather than his weapon. Each great city developed its own manner, Edo’s tested strength against Ōsaka’s polished brilliance, until demand thinned in the era’s last decades.
A Hozon-certified blade judged to show notably superior workmanship and a better state of preservation. The bar is higher: re-tempered blades and most unsigned Muromachi/Edo works are excluded.
The NBTHK (Nihon Bijutsu Tōken Hozon Kyōkai, the Society for the Preservation of Japanese Art Swords) is a public-interest incorporated foundation founded in 1948 and supervised by Japan’s Agency for Cultural Affairs (Bunkachō); it is based at the Japanese Sword Museum in Tokyo. Its expert panels physically examine each submitted work (shinsa) and issue a certificate (kanteishō) ranking it by artistic and historical merit. NBTHK papers are the most widely recognized standard of authentication for Japanese swords and fittings.
