The Heianjō school (平安城) of swordsmiths represents the principal lineage of Kyōto sword production during the Muromachi period. "Heianjō" is the classical name for Kyōto (Heian-kyō), and the school's smiths — resident in the Sanjō district of the capital — signed variously with the 平安城 (Heianjō) and 三条 (Sanjō) prefixes, a usage that has often caused them to be confused with the far earlier Sanjō school of Munechika.

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.
