This antique Japanese Wakizashi is attributed to Jyumyo from the Tenna era (1681-1684) of the mid-Edo Period. The Jyumyo school, originating from Yamato and later moving to Mino province, was renowned for its swords, often given as gifts to Daimyo due to the hopeful meaning of their name, 'longevity'. The blade features a cutting edge length of 52.0 cm and a curvature of 1.0 cm, and comes with an NTHK Kanteisho Certificate.

The NTHK’s principal certificate, issued for a blade of considerable quality. It confirms a genuine signature, or, for an unsigned (mumei) work, records the judges’ attribution to a smith or school. The paper carries a detailed worksheet with a numerical point score.
The NTHK (Nihon Tōken Hozon Kai, the Society for the Preservation of the Japanese Sword) is the oldest of Japan’s sword-appraisal bodies, founded in 1910, decades before the NBTHK. After the death of its long-serving head it divided into two successor societies, the NTHK and the NTHK-NPO, both of which continue to hold shinsa. NTHK certificates are known for a detailed worksheet that records a numerical point score alongside the judges’ written opinion, and the society is especially respected for its attribution of unsigned (mumei) work.
