This Long Sword (Tachi), a National Treasure, is said to have been made in the 12th century by Yasuie, a swordsmith from the end of the Heian period (late 8th century to late 12th century). It is unique in that it was definitely made by Yasuie.

The inscription on this sword resembles that of Yasutsuna*, not only in style but also in the position of the carving. In the history of Japanese swords, “The Chugoku region (the westernmost part of Japan’s main island, Honshu) is blessed with rich deposits of high-quality iron. […] The smiths working in the areas of Bizen (present-day southeastern Okayama Prefecture) and Hoki (modern western Tottori Prefecture) are especially well known.” **

This long sword, inscribed by Yasuie, is characterized by its slender body with a strong curve near the tsuka***, a fine itame pattern**** on the surface of the jigane*****, and a hamon****** with small, irregular patterns. This sword was passed down through the Kuroda family, the lords of the Fukuoka domain, and is currently housed in the Kyoto National Museum.
