A Sword Guard Signed Tōu: Yasuchika's Late Mastery in Pierced Copper
In 1730, at the age of sixty-one, the Edo metalworker Tsuchiya Yasuchika took Buddhist tonsure and began signing his pieces with a new name, Tōu. This sword guard, or tsuba, carries that late signature. It belongs to the final and most accomplished phase of a career that placed him among the most admired metalsmiths of eighteenth-century Japan.
The guard stands 8.4 centimeters tall and 8.1 wide, with a rim a little over 4 millimeters thick. Its body is suaka, a refined copper with a warm reddish surface. Across the left half Yasuchika pierced the shape of fishing nets hung out to dry; across the right, a scatter of plovers in flight. Touches of gold, rubbed into the metal rather than seated in it, catch the light at the edges of the carving.
The Man Behind the Signature
Yasuchika was born in 1670 in the castle town of Tsuruoka, in Dewa Province (present-day Yamagata Prefecture), the son of a retainer of the Shōnai domain. His given name was Yagohachi. He first trained locally under Satō Chinkyū, married Chinkyū's daughter, and in 1703, at thirty-four, moved to Edo. There he entered the workshop of Nara Tatsumasa and absorbed the manner of the Nara school.
His standing rests on a simple fact: collectors came to rank him with Nara Toshinaga and Sugiura Jōi as one of the Nara sansaku, the three great masters of that school. Of the three he left the largest body of work, across guards, hilt collars, menuki, and small knife handles. He worked outside the official Gotō house that served the shogunate, in the freer tradition known as machibori, or town carving, and his pictorial instinct set him apart.
Why the Guard Was Designated
Japan recognized the piece as an Important Cultural Property on November 14, 1953. The designation rests in part on technique. Records of the Agency for Cultural Affairs single out the rubbed gold inlay, suritsuke-zōgan, as something Yasuchika is credited with originating. Instead of cutting a channel and seating a wire of gold, the method presses and burnishes soft gold directly onto the prepared copper, leaving a flush, painterly accent with no raised edge.
Openwork was the discipline he handled best, and here he used it to organize the whole composition. The two hitsu-ana, the openings normally cut for a small utility knife and a skewer, have been filled with gold, so that nothing competes with the carved scene. Specialists regard the guard as a representative work from his maturity, made once his late style had fully settled.
Reading the Design
Stand close and the subject resolves into two moods held in a single frame. The drying nets on the left are heavy, geometric, anchored. The plovers on the right break that order, wheeling in loose formation across open ground. A coastal scene has been compressed onto a disc roughly the width of a hand.
The choice of suaka matters to the effect. Its soft red ground gives the gold its glow and keeps the surface calm where a darker alloy might have looked busy. Plovers, called chidori in Japanese, carried long associations in classical poetry with shorelines and the turning seasons, and Yasuchika returned to them often. A related guard of his, built around the Hamamatsu chidori design, is likewise an Important Cultural Property.
Where to See Yasuchika's Work
This particular guard is held privately, by the Tokyo firm Hōeidō, and is not on regular public view. Travelers who want to see metalwork of this calibre in person still have good options.
In Tokyo, the Nezu Museum holds the Mitsumura collection of sword fittings, more than three thousand pieces gathered to keep such work from leaving Japan, and rotates fine examples through its galleries. The Tokyo National Museum shows guards and fittings in its Japanese galleries on a changing schedule. To follow Yasuchika back to his roots, the Homma Museum of Art in Sakata, Yamagata, near his birthplace, owns and displays his work, and the Kurokawa Institute of Ancient Cultural Studies near Kobe holds his Important Cultural Property guard depicting the Zen figure Bukan. Checking current exhibition listings before a trip is the surest way to catch a tsuba on display.

Q&A
- What exactly is a tsuba?
- A tsuba is the guard mounted between the blade and the hilt of a Japanese sword. It protects the hand and balances the weapon, and by the Edo period it had also become a surface for some of the country's finest metalwork.
- Who was Tōu?
- Tōu was the art name Tsuchiya Yasuchika adopted in 1730, after taking Buddhist vows. A signature reading Tōu marks a piece from the last and most refined stretch of his career.
- What makes the gold inlay special?
- The technique is suritsuke-zōgan, in which soft gold is rubbed and burnished onto the copper rather than set into cut grooves. Records credit Yasuchika with originating it, and it gives the surface a flush, drawn quality.
- Can I see this guard in a museum?
- Not on a regular basis. It is privately owned and not on standing display. For comparable work, the Nezu Museum and Tokyo National Museum in Tokyo, and the Homma Museum in Yamagata, are reliable places to start.
- Why plovers and fishing nets?
- Both belong to a coastal vocabulary long loved in Japanese art and poetry. Plovers, or chidori, evoke shorelines and the turn of the seasons, and Yasuchika used the motif more than once across his career.
