Tsubame-Sanjo: Japan's Metalwork Town and Its Cutlery
In brief
Tsubame-Sanjo is a metalworking region in Niigata Prefecture, Japan, made up of two neighboring cities, Tsubame and Sanjo. Its metalwork goes back to nail-making in the early 1600s. Today Tsubame is best known for flatware and tableware, and Sanjo for knives and tools. "Made in Tsubame" on a fork or spoon usually means it was pressed, shaped and polished by specialist workshops within a few miles of each other.
If you've turned over a good spoon or fork and seen "Tsubame" or "Tsubame-Sanjo" stamped on the back, you've met one of the world's great metalworking towns without leaving your kitchen. Tsubame-Sanjo is where much of Japan's metal flatware is made, and where many of its best-known kitchen knives are forged. It's also where our own cutlery begins, before it travels to Kyoto to be finished in urushi lacquer. Here's what the region is, how it got here, and what "made in Tsubame" tells you as a buyer.
Where Tsubame-Sanjo is
Tsubame and Sanjo are two cities side by side on the Echigo Plain in Niigata Prefecture, on the Sea of Japan side of Honshu. The Shinano River, Japan's longest, flows through the area. Together they're known as Tsubame-Sanjo, and the name is written on the local Joetsu Shinkansen station. From Tokyo, the bullet train takes about two hours.
The two cities have a friendly rivalry. The shinkansen station is called Tsubame-Sanjo, while the nearby expressway interchange is Sanjo-Tsubame. Each city comes first once.
A short history: from nails to fine flatware
According to Japan's national tourism organization, JNTO, local artisans developed the craft of making Japanese-style nails in the early Edo period. Niigata Prefecture's own account ties this to the 1600s. The Shinano River flooded often, and farmers took up nail-making as a side business when their fields were under water. Those hand-forged nails, known as wakugi, sold well in fast-growing Edo, today's Tokyo. Merchants carried them there by river and boat.
Over the next centuries the skills spread. Workshops moved from nails to files, tools, blades, tobacco pipes and hammered copperware. Tsubame's hammered copper (tsuiki) is still made today. When Western-style dining came to Japan, Tsubame's metalworkers turned to spoons and forks. After World War II, stainless steel flatware from Tsubame was exported around the world, including to the United States.
Today, JNTO notes that the cutlery used at the Nobel Prize banquet in Stockholm each year is produced in the Tsubame-Sanjo area. It's a good shorthand for where the region's flatware stands.
Tsubame vs. Sanjo: flatware and blades
The two cities grew from the same roots but lean in different directions.
| Tsubame | Sanjo | |
|---|---|---|
| Best known for | Flatware (spoons, forks, knives for the table), tableware, housewares, hammered copper | Kitchen knives, carpentry and garden tools, hardware |
| Signature skills | Pressing, shaping and high-level polishing of metal | Forging blades, sharpening |
| What you might own | A stainless flatware set, a kettle, a copper pot | A Japanese chef's knife, a pair of pruning shears, a plane |
In practice the line blurs. There are knife makers in Tsubame and tableware makers in Sanjo, and the region works as one large cluster. A single fork might be pressed at one workshop, shaped at another and polished at a third. Polishing is its own specialty in Tsubame. The mirror finish on many famous products is the work of dedicated polishing shops.
What "made in Tsubame" tells a buyer
A place name isn't a quality guarantee on its own. Tsubame makes flatware at every price point, from hotel basics to high-end designer pieces. But it does tell you a few useful things:
- Specialist workshops. The piece comes from a region where metal flatware is the core business, not a sideline.
- Attention to finishing. Tsubame's reputation rests on edges, balance and surface finish. Those are the things you notice in the hand and at the mouth.
- Traceability. Brands that name the region usually know exactly where their pieces are made, and they're proud of it.
What to still check: the steel grade (18-8 or 18-10 stainless is common for flatware), weight and balance, the finish on the back of spoon bowls and between fork tines, and the care instructions. Most plain stainless flatware from Tsubame is dishwasher-safe. Coated or plated pieces depend on the finish, so read the maker's guidance. For chopsticks specifically, see dishwasher-safe chopsticks by material.

From Tsubame-Sanjo to Kyoto: two layers of craft
THE URUSHI's stainless steel cutlery is made in two places, by two different kinds of specialist. We call it two layers of craft.
The steel base
Our chopsticks, chopstick rest, spoon and fork start as stainless steel bases made with Tsubame-Sanjo precision metalwork. That gives us what the region does best: accurate shapes, clean edges and good balance. Our current spoon and fork use a slim teardrop shape that sits easily in the hand.
Six rounds of urushi, each heat-cured
The bases then travel to Kyoto, where our lacquerers finish them in natural urushi. The maker is Wakabayashi Butsugu Mfg. Co., Ltd., founded in Kyoto in 1830. The workshop has nearly 200 years of urushi work on Buddhist altars, including the restoration of national treasures.
The technique is yakitsuke, or heat-cured urushi. Its roots go back roughly 500 years, when it was used to protect armor from rust. Natural urushi is applied to the steel and cured at 120–170°C. The heat cures it almost instantly into a tough, hard-wearing finish. Each piece is coated and heat-cured six times, three rounds for each half. The result:
- A soft, gentle feel at the lips instead of cold bare metal.
- A finish that resists peeling and withstands dishwasher heat and water pressure. The stainless pieces are dishwasher-safe.
- A deep black that stays deep black. (Care is simple; see how to care for lacquer chopsticks.)
More detail on the process is in yakitsuke urushi on stainless steel. The spoon and fork are also shown on our Spoon & Fork product page, though store stock is very limited.
The full collection is on Kickstarter until November 14, 2026, with rewards expected to ship around March 2027. The Full Set includes chopsticks, a chopstick rest, a spoon and a fork. It retails at $198 and starts from $149 at the limited Super Early Bird tier.

Visiting Tsubame-Sanjo
Tsubame-Sanjo is an easy trip from Tokyo on the Joetsu Shinkansen. Some factories let visitors watch production, from kitchen knives to copperware, and a few offer hands-on experiences. The region also holds an annual factory festival, when many workshops open their doors to the public. Dates and participating workshops change each year, so check before you go.
