A Tiger Crouching in the Storm: The Masterpiece Tsuba by Nara Toshinaga at the Tokyo National Museum
Tucked away among the treasures of the Tokyo National Museum is a small disc of iron, no larger than the palm of a hand, that captures one of the most dramatic scenes in all of Japanese metalwork. The "Hand Guard with the Motif of a Fierce Tiger in the Rain" (Uka mōko-zu tsuba), signed by the master Nara Toshinaga, depicts a tiger crouching on a rock at the mouth of a cave as wind-driven rain lashes down and waves churn at its feet. Designated an Important Cultural Property of Japan in 1955, this 7.4-centimeter sword guard is considered one of the finest works ever produced by the storied Nara school of Edo metalworkers, and it offers visitors a rare opportunity to encounter samurai-era artistry at the very highest level.
What is a Tsuba?
A tsuba is the guard fitted between the blade and the grip of a Japanese sword. It serves a practical purpose — protecting the swordsman's hand and balancing the weight of the weapon — but from the late 16th century onward, the tsuba also evolved into one of the most expressive miniature canvases in Japanese art. Carved, pierced, and inlaid with gold, silver, and copper alloys, these palm-sized objects became personal statements of taste, fortune, and philosophy for the warriors and wealthy townspeople who commissioned them.
By the mid-Edo period (the late 17th and 18th centuries), a flourishing community of metalworkers had grown up in the shogunal capital, working not only for the ruling Tokugawa house but also for an increasingly affluent merchant class. It was within this lively, competitive milieu that Nara Toshinaga produced the tsuba on display.
The Master Behind the Work: Nara Toshinaga
Nara Toshinaga (1667–1736), known by the common name Tahei, was born in Edo and trained within the Nara school, the oldest of the independent Edo lineages of sword-fitting artisans. The school traced its origins to Nara Toshiteru, a lacquerer who had worked on the construction of the Nikkō Tōshōgū shrine before his descendants turned to metal craft. By the time Toshinaga rose to prominence, the Nara school had become a stylistic alternative to the official Gotō family, which served the shogunate and worked in a highly formalized manner.
Because Toshinaga did not hold an official appointment, he had the freedom to experiment with subject matter and technique. He is celebrated above all for his takabori, or high-relief carving — a method that allows the carved figures to project boldly outward from the metal ground. Together with Tsuchiya Yasuchika and Sugiura Jōi, he is counted among the so-called Nara Sansaku, the "Three Great Masters of Nara," and he is often considered the most technically gifted of the three. Toshinaga produced relatively few tsuba in his lifetime, devoting much of his energy to the production of fuchigashira (the collar and pommel fittings of a sword hilt), which makes this surviving guard all the more precious.
Why This Tsuba Is an Important Cultural Property
On February 2, 1955, the Japanese government designated this tsuba an Important Cultural Property under the Law for the Protection of Cultural Properties. Several factors contributed to its recognition.
First, surviving tsuba by Toshinaga are exceptionally rare. While many of his fuchigashira are extant, only a small handful of his sword guards have come down to us — all of them characterized by thick iron grounds and sculptural, three-dimensional designs. This piece, alongside his "Ōmori Hikoshichi tsuba" and "Mure Takamatsu tsuba," is widely considered one of his finest works in the format.
Second, the technical execution is remarkable even by the standards of the period. The artist combined no fewer than five distinct techniques in a single object: takabori (high relief) for the tiger and the crashing waves, sukidashibori (relief carved out from the surrounding ground) for the swirling clouds, kebori (fine hairline engraving) to suggest the streaks of driving rain, kosukashi (small openwork) to hollow out the mouth of the cave, and zōgan (metal inlay) of gold for the tiger's stripes and of gold and silver for the foam of the breaking waves.
Third, the design embodies a distinctive aesthetic vision. Rather than the calm, decorative motifs favored by the Gotō school, Toshinaga gives us a moment of raw natural drama — a creature poised between repose and explosive movement, set against the elemental forces of wind, rain, and sea. The piece is at once a technical tour de force and a small theater of mood and tension.
Highlights to Look For
When viewing the tsuba, several details reward close attention. The tiger itself dominates the front of the guard, its body coiled on a rocky outcrop in the classic pose known as bankyo (crouched and watchful). The animal's striped coat is rendered in gold inlay, and its musculature is modeled so deeply that the figure casts genuine shadows across the iron surface.
Just above and to the upper left, banks of cloud roll across the sky, carved in lower relief to give a sense of distance. Between cloud and rock, fine vertical lines etched into the iron evoke the falling rain. The cave behind the tiger is suggested by a small open void cut clean through the plate, a touch of negative space that lends the composition its depth.
Below, the lower half of the guard is filled with surging waves carved in bold high relief, their foaming crests accented with gold and silver inlay. The reverse side mirrors the same scene viewed from behind — a sophisticated three-dimensional conceit that few sword guards achieve. Look closely and you will see the precision with which the artist controlled the contrast between dense passages and quieter areas, an effect described in Japanese as the conscious balancing of soumitsu, density and rarefaction.
Visiting the Tokyo National Museum
The tsuba is part of the collection of the Tokyo National Museum, Japan's oldest and largest national museum, located in Ueno Park in central Tokyo. Founded in 1872, the museum houses more than 120,000 objects, including some 90 National Treasures and more than 660 Important Cultural Properties.
Items such as this tsuba are typically displayed on a rotational basis within the Japanese Sword and Sword Fittings gallery in the Honkan (Japanese Gallery). Because the museum cycles its collection regularly, visitors hoping to see this specific piece are advised to check the current exhibition schedule on the museum's official website before traveling. Even if this particular guard is not on display, the museum's standing exhibition of swords, fittings, and related arms is one of the finest in the world.
Around Ueno Park
The Tokyo National Museum stands at the northern end of Ueno Park, an expansive cultural district that is one of Tokyo's most rewarding areas to explore. Within a short walk you will find the National Museum of Western Art (a UNESCO World Heritage site designed by Le Corbusier), the National Museum of Nature and Science, the Tokyo Metropolitan Art Museum, and the Ueno Royal Museum. Ueno Zoo, Japan's oldest zoo, lies just to the west of the museum complex.
South of the park, the lively Ameyoko shopping street offers a contrasting experience — narrow lanes packed with fresh seafood, dried goods, snacks, and bargain shops. Kaneiji Temple, the great Tokugawa-era temple that once stood across the entire site of Ueno Park, has surviving subsidiary structures scattered throughout the grounds, including its five-story pagoda within the zoo and the Kiyomizu Kannon-dō hall modeled on Kiyomizu-dera in Kyoto. In springtime, the park's roughly 1,000 cherry trees draw visitors from across Japan and the world.

Q&A
- What does the title "Uka mōko-zu tsuba" mean in English?
- It can be translated as "Hand Guard with the Motif of a Fierce Tiger in the Rain." "Uka" means "under the rain," "mōko" means "fierce tiger," and "tsuba" is the guard fitted between a sword's blade and grip.
- Why is a tiger depicted on a Japanese sword guard?
- Although tigers are not native to Japan, they were known through Chinese and Korean painting traditions and came to symbolize courage, strength, and martial prowess. Pairings of tigers with dragons or with bamboo were common motifs in samurai material culture, and a fierce tiger in a storm conveyed both natural power and a warrior's resolve.
- How old is this tsuba?
- It was made during the Edo period, in the late 17th or early 18th century, by Nara Toshinaga (1667–1736). It is therefore approximately 300 years old.
- Can I always see this piece on display?
- No. Like most works on paper, lacquer, and metal at the Tokyo National Museum, this tsuba is shown on a rotational schedule to protect it from prolonged exposure. Visitors are encouraged to consult the museum's current exhibitions page before their visit.
- What other works by Nara Toshinaga are well known?
- His most celebrated tsuba include the "Ōmori Hikoshichi tsuba," depicting a famous medieval legend, and the "Mure Takamatsu tsuba." He is also widely admired for his fuchigashira — the collar and pommel fittings of sword hilts — which survive in considerably greater numbers than his tsuba.
