This antique Edo period kozuka, crafted in the Goto-style, depicts a scene of Jigoku Zu (Buddhist hell) with figures suffering in high relief carving. The background features a nanako ground, and the piece comes with an NTHK Kanteisho certificate. Please note that only the kozuka case is included, not the small knife.

Unsigned
NTHK (NTHK)
The NTHK’s principal certificate, issued for a fitting 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.
