This is a magnificent katana by the Mukansa swordsmith Yakuwa Yasutake, made in Showa 42 (1967) at the age of 58. It is a grand work exceeding three shaku in length, crafted with a wide and thick body, high koshi-zori, and a deeply carved bo-hi. The jitetsu shows an old-fashioned hada with a mix of itame and komokume, covered in thick ko-nie, while the hamon is a gunome-choji midare with varied patterns and bright nie-deki.

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.
