Tachi Signed "Kunihiro": A Momoyama Master's Blade on Mount Koya

High in the cedar forests of Mount Koya, the headquarters temple Kongobu-ji keeps a long sword signed with two characters, Kunihiro. The blade dates to the Momoyama period, the turn of the sixteenth into the seventeenth century, and is generally identified as the work of Horikawa Kunihiro, one of the smiths who pulled Japanese sword-making out of a long decline.

Kunihiro's life reads like a soldier's. Born in Hyuga in Kyushu and tied to the service of the Ito family, he spent years as a masterless wanderer before settling at Ichijo Horikawa in Kyoto, the district that gave his school its name. There he gathered the pupils who would become the prolific Horikawa group, and his own forging brought a fresh, open vigor to a craft that had grown formulaic. He died in 1614, said to be eighty-four. Among the great names of the so-called new-sword revival, he stands near the front.

The Blade and Its Golden Mounting

What sets this piece apart on Koya is its mounting. The blade is fitted in an ikakeji tachi koshirae, a scabbard whose surface is packed densely with gold dust under lacquer and then decorated in maki-e, so that the whole sheath glows like worked metal. The fittings were made by the metalworker Shoami Tsuneyoshi, and the mounting is registered together with the blade.

The sword entered the national registers early, listed as a national treasure under the prewar system on 14 April 1913, and was confirmed as an Important Cultural Property on 29 August 1950 when the present law took effect. A signed, two-character Kunihiro of this period is a satisfying thing to study: the maker's open, confident hand belongs to a moment when smiths were consciously reaching back to older traditions and forging something of their own.

Seeing It on a Sacred Mountain

Mount Koya is itself the draw. Founded by the monk Kukai in the early ninth century as the center of Shingon Buddhism, the mountain is part of the World Heritage site "Sacred Sites and Pilgrimage Routes in the Kii Mountain Range." Reaching it is half the pleasure: a train up the valley, a cable car to the rim, and then a temple town spread along a high plateau ringed by peaks.

The sword belongs to Kongobu-ji and is cared for by the Koyasan cultural-properties body, which runs the Reihokan, the mountain's treasure museum. Blades and other fragile holdings are rotated through its galleries rather than shown all at once, so the Kunihiro tachi is a periodic, not a permanent, sight. Before traveling with this object in mind, check the Reihokan's current exhibition to confirm it is on view. Even when the blade is resting, the mountain offers the great cemetery of Okunoin, the central temple complex, and lodging in working monasteries.
