Description

Hosokawa Tadamasa was the eldest son of Hosokawa Tadayoshi and worked as a smith for the Nobeoka domain in Hyūga province; the signature ties his activity to Shimōsa and to Nobeoka. The blade measures 72.1 cm of nagasa with a sori of 1.1 cm, giving a long, barely curved outline, and it is broad and substantial in weight: 920 g bare and 1,300 g when mounted. The tang remains ubu, unshortened, with a single mekugi-ana, so the signature survives in full. It is dated the eighth month of Keiō 4 (1868), the year of the Meiji Restoration, an uncommon detail that fixes the work to a precise moment. The blade carries NBTHK Tokubetsu Hozon papers. It comes with koshirae and shirasaya, although the original seller gives no detail on the fittings of the mounting and makes no statement about the blade's state of preservation.

The mounting starts from what is known of its period, adds what vouches for it (its own NBTHK paper, a signed fitting, a crest) and subtracts what has been restored (saya, ito, same, habaki or sageo).
