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 modern tachi by smith Masahira, a reproduction of the famous National Treasure 'Daihannya Nagamitsu'. It features a nagasa of 73.8 cm and a sori of 2.7 cm, closely mimicking the original's form and dimensions. The blade comes with a shirasaya and a silver tachi habaki.

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.
