Hirashimizu-yaki Zankin Glaze Yunomi: Yamagata Pottery Tea Cup [2026]

Hirashimizu-yaki (平清水焼, “Hirashimizu ware”) is a stoneware pottery made in the Hirashimizu district at the foot of Mt. Chitose, on the edge of Yamagata City in the Tōhoku region. The kilns there dig iron-rich clay straight out of the mountain, then fire it under a pale celadon glaze. As the pot heats, iron in the body melts up through the glaze and surfaces as fine brown-black speckles — the effect the kilns call nashiji-yu (梨地釉, “pear-skin glaze”). The yunomi (湯のみ, everyday tea cup) covered here is a working example of that body, made by Seiryu-gama (青龍窯), one of the district’s surviving kilns.

What makes this piece interesting to an international reader is not luxury — it is everyday-ware honesty. The companion glaze, zankin-ji, is a celadon whose dark flecks rising through pale green are meant to read like 残雪 (zansetsu), snow lingering on bare earth at the end of a Tōhoku winter. That image is the whole point: a cup that carries its region’s climate on its surface. Yamagata is far better known abroad for cast-iron kettles and Tendō wooden shogi pieces, so a Yamagata pottery is genuinely uncommon outside Japan.

This guide is written for readers deciding whether a Hirashimizu yunomi is worth importing — what the body and glaze actually are, where the craft sits in Yamagata’s history, how it compares to other Japanese yunomi already covered on this site, and the honest gaps in the available data. The fetched product feed for this item came back empty, so pricing and exact dimensions are flagged as unconfirmed throughout rather than guessed.

Who this is for — and who should skip it

Product overview (from published specs)

The table below is built from the spec brief and the item identifier. Where the fetched listing returned nothing, the cell reads “Unconfirmed” rather than a guessed value. Only the Amazon JP listing reference (ASIN B0FQTWJ78F) was available; live pricing and dimensions were not present at the time of writing.

Sources for this overview: Amazon US search (primary, moonill-20), Amazon JP Global Store (secondary, moonill-22 — the sourced listing), and maker-direct kiln information. The Amazon US search path carries comparable Japanese yunomi from other makers; the specific Seiryu-gama piece is sourced from Japan.

Price snapshot across stores

JPY is the authoritative price for the specific item; USD figures elsewhere are estimates at a ¥150/USD baseline (mid-2026). At the time of writing the live feed returned no price for this listing, so the JPY cell below is marked unconfirmed — verify on the listing before buying.

What it does well

Weaknesses and things to verify before buying

1. No confirmed price. The fetched feed returned no price for ASIN B0FQTWJ78F. Treat every figure as “verify on listing” until you open the live page.
2. Capacity, weight, and dimensions are unconfirmed. If you need a specific volume (e.g., a larger sencha cup), confirm on the listing — these were absent from the data.
3. Care specs unknown. Microwave and dishwasher suitability were not stated. Hand-washing is the safe default for speckled stoneware until the maker confirms otherwise.
4. Handmade variation. Iron speckling and glaze tone shift from cup to cup; the one you receive will not match a catalog photo exactly.
5. Lesser-documented craft. Hirashimizu-yaki is far less written-about in English than Yamagata’s cast iron or Tendō woodwork, so cross-checking specs is harder.
6. Cross-border fragility and customs. Ceramics break in transit; factor in protective packing, possible customs duties above your local threshold, and slower international delivery.

Where this comes from

Yamagata Yamagata · Tōhoku

Yamagata City lies in a mountain-ringed basin in southern Yamagata Prefecture, in the Tōhoku region of northern Honshū. Hirashimizu is a district on the city’s edge, at the foot of Mt. Chitose. The craft took root here for the most direct reason a pottery can: the raw material is in the ground. The kilns dig iron-rich clay straight from the mountain, and that iron is what later surfaces through the glaze as the ware’s signature speckle.

The region’s craft economy was built on water and trade. The Mogami River, which drains the Yamagata basin toward the Sea of Japan, carried goods out of a landlocked province; the river trade and the wealth of benibana (safflower) dye — Yamagata’s great Edo-period cash crop — funded a dense local culture of artisanship under the Yamagata domain.

The historical anchor here is everyday, not imperial. Hirashimizu-yaki was never court ware or a daimyo’s prestige kiln; it was a working district pottery that grew alongside a thriving dye-and-river economy. The exact founding is recorded as the Bunka era of the late Edo period — early 1800s — rather than a single documented year, so this guide gives the era rather than inventing a date.

“The iron that darkens the glaze was never added — it was always in the mountain, and the fire only brings it to the surface.”

What “still being made here” means is modest and concrete: two main kilns, Seiryu-gama and Heikichi-gama, still working the same Mt. Chitose clay into everyday tableware. They have adapted the line to modern kitchens — alongside yunomi and mugs, the kilns now make ceramic coffee drippers — which is exactly how a working folk pottery survives. It stays useful. This is a pottery counterpart to Yamagata’s better-known cast iron and Tendō woodwork: same prefecture, same domain heritage, different material.

Seasonally, the zankin “lingering snow” glaze is not an accident of marketing. Tōhoku winters are long and snow-deep, and a celadon whose dark flecks surface through a pale ground genuinely echoes the look of late-season snow thinning over dark earth — the kind of regional image a Yamagata maker would recognize on sight.
