The Waki-Goto tradition designates the branch and collateral lines of the Goto mainline (soke) that sustained the family's metalworking legacy across generations while extending its reach beyond the central house in Kyoto and later Edo. The Goto family itself constituted the preeminent dynasty of sword-fitting craftsmen in Japanese history, serving successive shogunal families from the Muromachi period through the Edo era.

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.
