Sword (inscribed Yoshimitsu)

A Sword Just 22.9 Centimeters Long

The blade fits within the span of two open hands. Signed simply "Yoshimitsu" on its tang, this short, double-edged sword, known as the Hakusan Yoshimitsu, belongs to Shirayama Hime Shrine in Ishikawa Prefecture and was designated a National Treasure of Japan on March 29, 1952. Sword scholars routinely call it the finest surviving example of the ken, the straight, symmetrical blade form that predates the curved Japanese sword.

A ken is not a fighting weapon in the usual sense. Modeled on ancient Chinese straight swords, it was forged mainly for Buddhist ritual, often placed before altars or held by statues of the deity Fudo Myoo. Few smiths made them, and fewer still made them well. That this one came from the hand of Toshiro Yoshimitsu, the most celebrated of all Kyoto's Awataguchi smiths, explains much of its fame.

The Smith: Awataguchi Toshiro Yoshimitsu

Yoshimitsu worked in the Awataguchi district of Kyoto in the mid-Kamakura period, the thirteenth century. Tradition holds that he was the son of either Norikuni or Kuniyoshi, two earlier masters of the school, though the genealogy remains uncertain. His reputation rests overwhelmingly on tanto, short daggers prized for their refined steel; centuries later, the Kyoho Meibutsucho, the shogunate's register of famous blades, ranked him alongside Masamune and Go Yoshihiro as one of the three great smiths of Japan.

Ken by Yoshimitsu are rare. His teacher's generation, particularly Kuniyoshi, left several, but among Yoshimitsu's surviving works the form is exceptional. The official record of the Agency for Cultural Affairs notes that the forging and tempering of this blade surpass even his daggers in the strength and clarity of its crystalline steel.

Look closely when it is on display. The blade is ground with a central ridge on both faces, a construction called ryoshinogi-zukuri, and both edges are sharpened. The tip does not flare; the surfaces carry a gentle fullness of flesh. The grain is a tight, fine itame, like polished pear skin, and the temper line runs straight with small feet of hardened steel reaching into it, in places doubling into a faint second line. These are details visible to the naked eye through museum glass, and they reward patience.

From the Shogun's Household to a Mountain Shrine

In December 1633, a bride left Edo for Kanazawa. She was Ohime, also recorded as Achiko, a daughter of Tokugawa Yorifusa of Mito who had been adopted by the third shogun, Tokugawa Iemitsu, before her marriage to Maeda Mitsutaka, lord of the Kaga domain. This sword traveled with her as part of her trousseau. How the blade entered Tokugawa hands in the first place is not documented; it is presumed to have belonged to either the shogunal house or the Mito branch.

The marriage tied Japan's wealthiest domain to the ruling house, and the dowry was assembled accordingly. Ohime died in 1657, having taken the Buddhist name Seitaiin. Her son Maeda Tsunanori, who governed Kaga for some eight decades, dedicated the sword to Shirayama Hime Shrine in prayer for his mother's repose; records place the offering in 1657 or the following year. From then on it has been the shrine's treasure, and the nickname Hakusan Yoshimitsu, after the sacred mountain, replaced whatever name it may have carried before.

The blade had already been recognized under the prewar system in 1909. The 1952 designation confirmed its standing under the current Law for the Protection of Cultural Properties.

Where and How to See It

The sword does not reside at the shrine. For safekeeping it is deposited at the Ishikawa Prefectural Art Museum in Kanazawa, a short walk from Kenrokuen garden, and it appears in the museum's collection exhibitions roughly once a year, often in autumn displays of Ishikawa's cultural properties. A dedicated 2024 exhibition paired it with the Token Ezu, a 1595 album of sword drawings by the appraiser Hon'ami Kotoku. Photography rules vary by exhibition, so check the museum's website before planning a visit around it.

Shirayama Hime Shrine itself stands in the town of Tsurugi at the foot of Mount Hakusan, about thirty minutes by car from central Kanazawa or a fifteen-minute walk from Tsurugi Station on the Hokuriku Railway Ishikawa Line. It is the head shrine of more than two thousand Hakusan shrines across Japan and the ichinomiya, or first-ranked shrine, of the old Kaga province. Shrine tradition traces its origins to the reign of Emperor Sujin, and the ascetic Taicho is said to have opened the mountain's summit sanctuary in 718. The approach climbs through an avenue of cedars several centuries old; the shrine's treasure hall, open seasonally, displays other designated works from the collection, including documents and a celebrated saddle.

Nearby

Tsurugi is a compact former temple town worth an hour's stroll, with sake breweries and the Kinkengu shrine, one of the historic Hakusan Seven Shrines. In Kanazawa, the art museum sits within a cluster that includes Kenrokuen, Kanazawa Castle Park, and the 21st Century Museum of Contemporary Art, so a viewing of the sword folds easily into a day in the city. Travelers with more time can continue toward the mountain itself: the Hakusan Shirakawa-go White Road opens in the warmer months, and the summit trails draw climbers from July to October.
