Tachi Signed Yoshifusa: A National Treasure of Japanese Swordsmithing

Among the countless masterpieces of Japanese sword craftsmanship, the tachi signed "Yoshifusa" held at the Hayashibara Museum of Art in Okayama stands as one of the finest achievements of the Kamakura period. Designated a National Treasure, this magnificent long sword embodies the pinnacle of the Fukuoka Ichimonji school's artistry, renowned for producing some of the most flamboyant and technically accomplished blades in the history of Japanese swordmaking.

Forged in the 13th century by the master swordsmith Yoshifusa, this tachi captivates viewers with its dazzling chōji-midare (clove-blossom) tempering pattern—a hallmark of the Ichimonji tradition elevated to its most spectacular expression. For international visitors with an appreciation for the intersection of martial heritage, fine art, and meticulous craftsmanship, encountering this blade in person offers a uniquely moving experience.

The Fukuoka Ichimonji School and Master Yoshifusa

The Fukuoka Ichimonji school flourished during the mid-Kamakura period (13th century) in Fukuoka-shō, a settlement along the Yoshii River in Bizen Province—present-day Okayama Prefecture. The school earned the name "Ichimonji" (literally "one character") because many of its smiths inscribed only the character "一" on the tang of their blades rather than their full names.

Yoshifusa was the son of Sukefusa and emerged as the most celebrated figure among the Ichimonji smiths. Together with Norifusa and Sukesane, he is recognized as one of the three greatest masters of the school. While all Ichimonji smiths are known for their lavish chōji-midare tempering patterns, Yoshifusa's work is universally regarded as the most gorgeous and varied of the entire tradition. An astonishing five of his tachi have been designated as National Treasures—an honor that underscores his extraordinary place in the history of Japanese swordmaking.

Why This Tachi Is Designated a National Treasure

This particular tachi was first designated as an Important Cultural Property in 1933, and subsequently elevated to National Treasure status in 1955. Its designation reflects several exceptional qualities.

The blade is constructed in the shinogi-zukuri style with an iori-mune (gabled ridge line). It features a graceful koshi-zori (curvature near the base) with a slight saki-zori (forward curvature) and a medium-sized kissaki (point). The jihada (surface grain pattern) displays itame mixed with moku (burl-like patterns), over which a vivid midare-utsuri (irregular reflection pattern) appears—a characteristic feature of top-quality Bizen blades.

The hamon (tempering pattern) is a breathtaking nioi-fukai chōji-midare—deep, luminous clove-blossom patterns that ripple along the cutting edge with remarkable variety and rhythm. Among all known works by Yoshifusa, this blade is noted for its especially flamboyant and diverse hamon, making it one of the swordsmith's finest surviving achievements. The tang (nakago) remains in nearly its original condition, with a single peg hole (mekugi-ana), testifying to the blade's exceptional state of preservation. Both the jihada and hamon are described as supremely healthy—a remarkable condition for a blade over 700 years old.

Provenance and Historical Certificates

This National Treasure tachi comes with a distinguished provenance, having been handed down through the Matsudaira family of Saijō Domain in Iyo Province (present-day Ehime Prefecture). The Saijō Matsudaira were a branch of the powerful Kishū Tokugawa family, one of the three elite branch houses of the Tokugawa shogunate. The fact that this blade was treasured by such a high-ranking feudal family attests to its quality and prestige.

Accompanying the sword are two historical origami certificates—official appraisals by the Hon'ami family, who served as the foremost sword connoisseurs for the Tokugawa shogunate. The first certificate, issued by the 11th-generation appraiser Hon'ami Kōon in the second year of Meireki (1656), valued the sword at 15 gold pieces. A second certificate by the 13th-generation appraiser Hon'ami Kōchū, dated the first year of Shōtoku (1711), dramatically increased the valuation to 70 gold pieces—reflecting the growing esteem in which the blade was held over the decades.

Highlights and What to Look For

When viewing this tachi, visitors should pay special attention to several key features. The chōji-midare hamon is the blade's most striking visual element—look for the way the clove-blossom shapes vary in size and intensity along the length of the cutting edge, creating an impression of controlled exuberance. The depth of the nioi (luminous misty line along the hamon) gives the pattern a glowing, almost three-dimensional quality.

The midare-utsuri—a shadowy reflection pattern that appears on the flat surface of the blade—is another hallmark of the finest Bizen work. This optical phenomenon, caused by variations in the crystalline structure of the steel, adds an ethereal dimension to the blade's beauty and is considered extremely difficult to produce intentionally.

The nearly unaltered tang preserves the original signature "Yoshifusa" in the swordsmith's own hand, connecting modern viewers directly to the craftsman who created this masterpiece over seven centuries ago. The blade's overall condition—described by experts as "supremely healthy"—is remarkable and allows contemporary audiences to appreciate the work much as it would have appeared when newly forged.

The Hayashibara Museum of Art

The Hayashibara Museum of Art is located on the grounds of the former Okayama Castle ninomaru (secondary citadel), within the historic castle precinct of Okayama City. The museum was founded in 1964 based on the remarkable art collection of the Okayama industrialist Hayashibara Ichirō (1908–1961), who was a passionate collector of Japanese swords and classical art. The collection also incorporates heirloom items from the Ikeda family, the feudal lords of Okayama Domain.

The museum building was designed by the celebrated modernist architect Maekawa Kunio, whose other works include the Tokyo Metropolitan Art Museum. Visitors enter through a grand nagaya-mon (long gate), a historic samurai-era structure that survived the 1945 Okayama air raids and now serves as the museum's iconic entrance. With approximately 9,000 items including 3 National Treasures and 26 Important Cultural Properties, the museum holds one of the finest private collections of Japanese art in western Japan.

Please note that the museum does not maintain a permanent exhibition. Instead, it organizes four to five special exhibitions per year, rotating its collection thematically. The National Treasure tachi by Yoshifusa may not be on display during every exhibition period, so visitors are advised to check the museum's official website or contact the museum directly before planning a visit specifically to see this sword.

Nearby Attractions

The Hayashibara Museum's location in the Okayama Castle district makes it an ideal base for exploring several of the city's top cultural attractions. Okayama Castle, nicknamed "Crow Castle" for its striking black exterior, is just a short walk to the east and offers panoramic views from its reconstructed tower. Directly across the Asahi River lies Kōrakuen, one of Japan's celebrated Three Great Gardens, where visitors can stroll through beautifully landscaped grounds featuring ponds, tea houses, and seasonal flowers.

Art enthusiasts may also wish to visit the nearby Okayama Prefectural Museum of Art, which houses an important collection including works by the legendary ink painter Sesshū. For those interested in Japanese swords beyond this single visit, the nearby city of Setouchi in Okayama Prefecture is home to the Bizen Osafune Japanese Sword Museum, where visitors can observe swordsmiths at work and learn about the Bizen tradition that produced Yoshifusa and his contemporaries.
