Historical context

The Muromachi period (1392 to 1573)

›

After the Ōnin War broke the Ashikaga order, a century of Sengoku warfare armed nearly every province in Japan. The era rewards a discriminating eye: routine work exists in quantity, and beside it stand custom blades of the first rank.

The Muromachi period (1392 to 1573) →

NBTHK Certificate
Tokubetsu Hozon Tōken特別保存刀剣
Sword Especially Worthy of Preservation
›

A Hozon-certified blade judged to show notably superior workmanship and a better state of preservation. The bar is higher: re-tempered blades and most unsigned Muromachi/Edo works are excluded.
