Hyūga Masamune, Japanese tantō at Mitsui Memorial Museum in Chūō-ku, Japan
The Hyūga Masamune is a short blade distinguished by carefully applied hardening patterns and balanced proportions throughout its length. The blade's construction reveals the technical methods a Japanese master developed during medieval times.
Master swordsmith Masamune created this blade during the Kamakura period, applying techniques that pushed medieval Japanese sword making to its peak. His work became the standard by which later craftspeople measured their own skill.
The blade shows how Japanese craftspeople united steel and artistic skill to create an object that served both practical and aesthetic purposes. The fine lines visible on the surface tell of the maker's patience and hand control.
The blade is held at the Mitsui Memorial Museum, where careful environmental control protects the steel and surface patterns from damage. Visitors should allow normal viewing time and treat the display area with appropriate respect.
The blade carries hardening patterns so distinctive that experts can recognize Masamune's hand in them through their particular appearance. This personal signature developed from his unique working method and remains visible today.
