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 tachi made by Miyairi Kiyohira, born in 1924 in Nagano Prefecture. Kiyohira was the younger brother of the Living National Treasure Miyairi Akihira (Yukihira) and was also a highly regarded smith, receiving awards such as the Nagano Prefecture Art and Culture Achievement Award. The blade features a shinogizukuri shape with an o-kissaki and bohi engravings on each side.

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).
