This is a charming iron tsuba from the Kumagai school, featuring a chidori (plover) bird theme with elegant gold zogan accents. The school is known for makers like Kumagai Yoshitsugu and Yoshiyuki, with Yoshitsugu establishing the 'Edo Higo' style in Edo. This piece is a fine example for collectors interested in the Higo tradition.

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.
3 day inspection period on all sales. Items can be returned for any reason for a full refund, less return shipping cost. Returned items must be in the same condition as when purchased.
