Nagasone Okisato, who took the smithing name Kotetsu (虎徹), began his career not at the forge of the swordsmith but at that of the armorer, working as a katchūshi in Echizen Province. Around Meireki 2 (1656), when he was about fifty years of age, he relocated to Edo and changed his profession to swordsmithing, settling in the area of Tōeizan and Shinobugaoka. The setsumei record that his common name was Sannojō; he first signed Okisato, and after taking Buddhist vows styled himself Kotetsu Nyūdō. Learn more →

We could not find an authenticity certificate on the seller’s listing. Japanese swords and fittings are normally papered by the NBTHK (or the NTHK). Without one, the attribution is the seller’s own assessment and has not been independently verified — treat it with caution and ask the dealer about certification before buying.
