The twentieth century nearly killed the craft twice: wartime distortion, then the occupation ban. The NBTHK’s founding in 1948 and licensed forging from 1953 rebuilt the sword as an art, crowned by Living National Treasures and the mukansa rank.
This is a long katana by the Mukansa-rated smith Okubo Kazuhira, born in 1943 and a student of Miyairi Akihira. It features a robust Kamakura-period tachi-like sugata with a wide mihaba and deep koshi-zori. The jigane is a fine ko-itame with ji-nie, and the hamon is gunome-choji-midare with active hataraki.

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.
No cooling-off period or returns; refund only if the purchased sword is proven fake, capped at purchase price (excludes commission sales, accessories, auction items).
