Hirashimizu-yaki (平清水焼, “Hirashimizu ware”) is a stoneware tradition fired at the foot of Mt. Chitose (Chitoseyama) on the southern edge of Yamagata City, in the snowbound Tōhoku region of northern Honshu. Potting took hold here from around the An’ei era (1772–1781), worked from a local, iron-bearing clay dug at the mountain’s base; the early kilns are credited to a potter named Niwa Jizaemon. What sets the ware apart is not a decorator’s brush but the iron already in the ground.
In the kiln, that iron migrates to the surface and settles as dark brown-black specks scattered across a bluish-green celadon ground. Yamagata’s potters named the effect zansetsu (残雪, “remaining snow”) — the dark flecks read like patches of snow lingering on a green spring mountain — and pair it with a softer nashi-seiji (梨青磁, “pear-skin celadon”). The coffee cup and saucer covered here, from the still-active Shichiemon kiln (七右ェ門窯, Shichiemon-gama), is one of the more approachable forms this glaze takes.
This guide is written for international readers weighing a first piece of Yamagata pottery. It covers what the ware is, where it comes from, how to read the glaze, where the listing is sourced from, and the honest caveats — including the fact that the fetched price snapshot for this specific item came back empty, so live pricing must be checked at the retailer.

Who this is for — and who should skip it
- Want a celadon whose pattern comes from the clay’s own iron, not applied decoration
- Prefer a quiet, understated coffee cup over bright porcelain
- Are building a collection of regional Japanese kiln wares and lack a Tōhoku piece
- Appreciate seasonal naming (zansetsu, “remaining snow”) tied to a real landscape
- Are comfortable verifying price and stock yourself before ordering
- Want a uniform, machine-matched set — each piece’s iron spotting varies
- Need a confirmed price and fast Prime delivery today (this item ships from Japan)
- Expect dishwasher- and microwave-guaranteed durability without checking the listing
- Prefer vivid overglaze enamels (look to Kutani or Arita instead)
- Are unwilling to hand-wash and treat a stoneware glaze gently

Where this comes from — place, era, and the craft tradition
Yamagata City lies in a mountain-ringed inland basin in southern Yamagata Prefecture, in the Tōhoku region of northern Honshu. The Mogami River, which drains the basin and runs north to the Sea of Japan, historically carried both trade and clay through the same valleys where the kilns took root. The relevant geography is small and specific: Hirashimizu is a district at the base of Chitoseyama (Mt. Chitose), and it is the iron in that hill’s clay that makes the ware what it is.

The city’s historical anchor is Mogami Yoshiaki, the daimyō who built Yamagata into a major castle town around the turn of the 17th century. His castle, formally Yamagata Castle, is better known by its nickname Kasumi-ga-jō (霞城, “Misty Castle”). That castle-town economy gave the region the population and the demand a pottery district needs. Hirashimizu-yaki itself is younger than the castle: potting took hold at the foot of Chitoseyama from around the An’ei era (1772–1781), and the early kilns are credited to Niwa Jizaemon.
- c. 1600 — Mogami Yoshiaki builds Yamagata into a castle town around Kasumi-ga-jō (Yamagata Castle).
- 1772–1781 — An’ei era: potting takes hold at the foot of Chitoseyama using local iron-bearing clay.
- Late 18th c. — Niwa Jizaemon credited with establishing the early Hirashimizu kilns.
- 19th c. — The iron-spotted zansetsu celadon and nashi-seiji glazes emerge as the ware’s signature.
- 20th c. — The Shichiemon kiln (Shichiemon-gama) continues as a leading active maker.
- 2026 — Hirashimizu-yaki is still fired in Yamagata City from the same Chitoseyama clay.
What “still being made here” means is concrete: the Shichiemon kiln remains a leading active maker of Hirashimizu-yaki, working the same iron-bearing clay from the same hillside. The pattern is not painted on. It is the clay’s own iron migrating to the surface in the heat of the kiln — which is why no two pieces spot identically, and why the ware reads as a record of its own material rather than a decorator’s design.
“The snow on a Tōhoku mountain does not melt evenly — it lingers in dark pockets against the green. Hirashimizu’s potters did not invent that image; they let the clay’s iron draw it for them.”

The naming is worth dwelling on, because it is where the place and the object meet. Zansetsu means “remaining snow” — the patches that survive on a green spring mountainside after the thaw has started. On the cup, the dark brown-black iron specks against the bluish celadon read exactly that way. The companion glaze, nashi-seiji or “pear-skin celadon,” names a finer surface texture. Both belong to the snowbound Tōhoku climate that frames the ware and gave it its vocabulary.

The same valleys that hold the clay also carry the region’s older landmarks — Yamadera (Risshaku-ji), the cliffside temple complex on the city’s edge, and the Mogami River that historically moved goods through the basin. None of that is decoration on the cup. It is the context that makes a quiet celadon coffee cup legible as a Yamagata object rather than a generic one.

What it does well
Weaknesses and things to verify before buying
- No confirmed price. The fetched data returned an empty price snapshot. Check the live listing before assuming any figure.
- Spotting varies piece to piece. Because the pattern is the clay’s own iron, the cup you receive will not match catalog photos exactly. This is intrinsic, not a defect — but it disappoints buyers wanting uniformity.
- Dimensions and capacity unconfirmed. The listing snapshot did not include size or volume. If you need a specific cup capacity, verify before ordering.
- Care guidance unconfirmed. Dishwasher and microwave suitability are not stated in the available data. Stoneware glazes are generally best hand-washed; confirm with the listing.
- Ships from Japan. The sourced listing is Amazon JP Global Store. Expect longer transit than domestic Prime and possible customs duties above your country’s import threshold.
- Not a bright-enamel ware. If you want vivid color (Kutani, Arita overglaze), this restrained celadon will read as plain.
Conclusion — which buyer type are you?
Other ways to approach this purchase
🏆 Editor’s Pick
❓ Frequently Asked Questions
What does “zansetsu” mean, and is the pattern painted on?
Zansetsu (残雪) means “remaining snow.” The dark brown-black specks are not painted — they are iron from the local Chitoseyama clay surfacing during firing, resembling snow lingering on a green mountain. Because of this, every piece spots differently.
Where is Hirashimizu-yaki made?
In the Hirashimizu district at the foot of Chitoseyama in Yamagata City, Yamagata Prefecture, in the Tōhoku region of northern Honshu. Potting took hold there from around the An’ei era (1772–1781).
How much does this coffee cup cost?
The fetched listing snapshot did not include a price, so this guide does not quote one. Check the live Amazon JP Global Store listing (ASIN B00IUFQWEA) for current pricing and stock.
Can I have it shipped outside Japan?
Yes. The item is sourced from Amazon JP Global Store, which ships internationally to most major destinations. Expect longer transit than domestic Prime, and possible customs duties above your country’s import threshold. Proxy services like Buyee or Tenso are a fallback if a piece is only on a domestic shop.
Is it dishwasher and microwave safe?
The available data does not confirm this. Stoneware celadon glazes are generally best hand-washed, and metallic or decorated pieces should be kept out of the microwave, but you should verify the specific listing’s care guidance before assuming.
How is this different from a Kiso lacquer coffee cup?
They are entirely different genres. The Kiso piece is lacquered wood (warm, light, soft to the touch); Hirashimizu-yaki is iron-bearing stoneware with a celadon glaze (cool, hard, with a mineral-driven pattern). See our Kiso lacquer pair coffee cup guide to compare.
