This is an unsigned tanto attributed to Koyama Soji, a prominent swordsmith active during the late Edo period. The blade is in excellent condition, with no flaws and has been polished. The jigane shows itame and exhibits active hataraki, while the hamon features an uneven pattern of gunome lines.

Born in Kyōwa 3 (1803) at Shirakawa in Ōshū, Koyama Munetsugu (固山宗次) carried a smith's name read variously in the setsumei as Munobei or Sōbei, working under the art-names Issensai and Seiryōsai. He came up alongside elder brothers Munehira and Munetoshi, and although his teacher is traditionally given as Katō Tsunahide, the NBTHK readers repeatedly note that the hand of Katō Tsunatoshi shows through his work more plainly.

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.
As a general rule, returns/exchanges are not accepted on Japanese sword orders unless damaged upon delivery. Other items: returns/exchanges accepted within 7 days of delivery. Cancellation for personal reasons incurs a 30% restocking fee (70% refunded). Return shipping must be prepaid and insured by the buyer; shipping/handling fees are non-refundable.
