Ueda Tsumugi Silk Gamaguchi Coin Purse: Nagano’s Sanada-Era Weave [2026]

In the eastern hills of Nagano Prefecture sits Ueda, the old castle town of the Sanada clan — the family whose fortress famously turned back a Tokugawa army not once but twice. Long after the sieges ended, the same mountain valleys that fed the domain were turned to a quieter trade: raising silkworms and weaving cloth. Out of that history comes Ueda Tsumugi (上田紬), a pre-dyed striped silk that is counted among the three great tsumugi weaves of Japan.

This article looks at a small object cut from that tradition — a gamaguchi (がま口) coin purse made from striped saki-zome (先染め, “yarn-dyed before weaving”) Ueda Tsumugi silk, closed with a metal snap clasp small enough to drop into a pocket. It is not a kimono, not an heirloom obi; it is an everyday carry that happens to be woven on the same looms and in the same shima (縞, “stripe”) idiom that the region has used for generations.

Because production is craft-scale and largely domestic, this is one of those pieces where the buying path matters as much as the object. Below we cover what Ueda Tsumugi actually is, where it sits on the map and in Japanese history, who the purse suits, and — practically — how an international reader can buy one when US shelf availability is thin and the live listing carries no confirmed price.

Who this is for — and who should skip it

Product overview (from published specs)

The fetched listing snapshot for this item returned no structured spec fields and no confirmed price. The table below therefore reflects what the craft category establishes plus the spec brief for this piece; cells without a verifiable source are marked accordingly. Only the Amazon JP listing path is available for the specific item; live pricing was unavailable at time of writing.

Price snapshot across stores

JPY is the authoritative price for the specific listed item; the snapshot carried no confirmed figure at writing, so the JP cell reads “check listing.” USD figures elsewhere are approximate (¥150/USD baseline, mid-2026) and depend on the current exchange rate.

📦 Shipping note: Amazon JP Global Store ships small textile goods like this to most major destinations; expect roughly $15–$40 in international shipping to the US or EU, with higher rates elsewhere. Orders above your local de-minimis threshold may attract customs duty. Prices and stock fluctuate — verify at the retailer before buying.

What it does well

“The looms that now turn out a pocket coin purse once helped finance a domain — Ueda’s silk valleys were an engine of Meiji Japan’s raw-silk economy.”

Weaknesses and things to verify before buying

1. No confirmed price or dimensions. The listing snapshot returned neither, so treat size and cost as unknown until you open the live listing.
2. Thin US availability. Production is craft-scale and largely domestic; you will most likely buy through Amazon JP Global Store or a proxy rather than US Prime.
3. Silk needs care. This is not a wash-and-go item. Keep it dry, avoid abrasion against keys, and spot-clean rather than machine-wash.
4. Colorway varies. Stripe color and arrangement rotate with the maker’s stock, so the piece you receive may differ from any photo.
5. Coin purse, not a wallet. There are no card slots or billfold; it is meant for coins and small items.
6. International shipping and possible duties. Add forwarding cost and check your country’s customs threshold before committing.

Where this comes from

Nagano Nagano · Chūbu

Ueda is an inland castle town in eastern Nagano Prefecture, in the Chūbu region of central Japan. It lies in a basin along the Chikuma River, walled in by mountains — a cool, relatively dry valley whose slopes and terraces suited mulberry cultivation. That geography is the practical reason a silk industry took root here: where you can grow mulberry, you can raise silkworms, and where you raise silkworms, weaving follows.

The town’s name is bound up with the Sanada clan. Sanada Masayuki built Ueda Castle in the 1580s, and from it the Sanada twice turned back Tokugawa forces — most famously in 1600, when Masayuki and his son Yukimura delayed a Tokugawa army on its way to the decisive battle of Sekigahara. The Sanada are among the most celebrated names of Japan’s warring-states period, and Ueda is their home ground.

Under the Edo-period Ueda domain, the surrounding villages were directed toward raising silkworms and weaving, and the striped tsumugi they produced became one of the cloths the region was known for. When Japan opened to trade in the Meiji era, raw silk became the country’s leading export, and the silk-producing valleys of Shinshū — the old name for Nagano — were among the engines of that economy. The thread that the same hills produce today runs back through that history.

Ueda Tsumugi is counted as one of Japan’s three great tsumugi, alongside Yuki Tsumugi of Ibaraki and Ōshima Tsumugi of Kagoshima. It is a saki-zome silk: the yarn is dyed before weaving, so the crisp shima stripes are part of the cloth’s structure rather than printed onto it. The weave is a tight double-warp construction, and the cloth’s reputation for toughness is captured in the nickname “tategae sando” — traditionally said to mean it outlasts three changes of kimono lining. That is a folk saying about wearing quality, not a laboratory measurement, but it points to the trait that makes the textile suitable for an everyday object like a coin purse.

A gamaguchi cut from this cloth is a small extension of a much larger tradition. Production today is craft-scale and mostly domestic, which is why US shelf availability is thin while Japanese listings exist — a practical fact for any international reader, and the reason the buying paths in this article matter.
