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.
