Kasama Ware: Japan's Most Free-Spirited Pottery Town
When someone asks what kasama pottery looks like, there is no easy answer.
That is because kasama ware has almost no defining constraints on style at all.
Bizen Ware: Pottery With No Glaze at All has its unglazed earthy quality. Arita porcelain has its refined white body. Mashiko pottery has its mingei (folk craft) warmth. Most of Japan’s major kiln regions have a recognizable identity — a character that sets them apart. Kasama, by contrast, is known as “free kasama pottery” (jiyū na Kasama-yaki), a tradition so wide in its range of styles that it defies easy description. Hundreds of artists work here. And that freedom is Kasama ware’s greatest defining quality.
The History of Kasama Pottery
Kasama pottery’s origins trace back to the 1770s, in what is now Kasama City, Ibaraki Prefecture. A potter named Kuno Hanemon traveled to the Shigaraki region to learn ceramic techniques, then returned to establish a kiln in Kasama’s domain. This is the founding moment of the kasama pottery tradition.
The earliest kasama ware centered on practical objects for everyday life — large storage jars (kame), water jars, and tokkuri sake flasks of the kind used by farming and merchant households across the region. Durable and well-suited to daily work, these utilitarian pieces defined Kasama’s output for its first century.
The economic foundation that allowed the pottery industry to expand was Kasama’s exceptional geography. Kasama City is home to Kasama Inari Shrine — one of Japan’s three great Inari shrines — which drew worshippers from across the country, turning Kasama into a prosperous pilgrimage town. The steady flow of visitors created a reliable market for kasama pottery, giving the potters a stable livelihood.
This character as an “open gate town” — a place built around welcoming outsiders — may well have laid the cultural groundwork for the freedom of expression that defines kasama ware today.

Why Kasama Pottery Has No Fixed Style
The diversity of Kasama pottery accelerated sharply in the late twentieth century.
The pivotal moment was the opening of the Ibaraki Prefectural College of Ceramics in Kasama City in 1990. One of the very few dedicated ceramic arts colleges in Japan, it drew students from across the country who wanted to pursue pottery seriously. After graduating, many simply stayed — renting studios in Kasama, building their practices, and becoming permanent members of the local pottery community.
Several factors made Kasama an attractive place to put down roots: relatively affordable land and studio rents, an already-established community of working artists, and — crucially — the absence of any dominant stylistic lineage demanding conformity. These conditions created a kind of organic artist-in-residence environment that draws young ceramic artists from all over Japan.
Today, an estimated 300 to 400 independent ceramic artists work and live in Kasama City. The range of styles found within this single japanese pottery community is remarkable:
- Unpretentious everyday tableware in the tradition of Yanagi Soetsu’s mingei folk craft movement
- Minimal, architecturally influenced white porcelain forms
- Contemporary art-scale sculptural works that belong equally in a gallery
- Delicate painted pieces drawing on botanical and natural motifs
- Bold stoneware fired in wood kilns
There is no template for recognizing Kasama pottery by sight. What exists is each individual artist’s distinct voice. That is the essence of Kasama ware.
Japan’s Largest Ceramic Festival: The Kasama Himatsuri
No account of Kasama pottery is complete without its annual festival: the Himatsuri (Ceramic Fire Festival), held each year during Golden Week (late April to May).
Attendance typically reaches around 500,000 visitors. More than 200 kiln studios and ceramic artists exhibit together, bringing everything from everyday tableware to one-of-a-kind art pieces. Many artists give live wheel-throwing and underglaze painting demonstrations, and visitors can choose pieces while speaking directly with the makers.
Because purchases are made directly from the artists, prices are often more accessible than gallery retail, and the range of work on offer — from entry-level cups to collector-grade pieces — suits visitors of every level.
The festival site is immediately adjacent to the Ibaraki Ceramics Art Museum and the Kasama Craft Hill complex, making it easy to combine the festival with a visit to the museum in a single day.
For anyone who wants to buy contemporary japanese ceramics directly from working artists, the Kasama Himatsuri is one of the finest opportunities in Japan.

The Ibaraki Ceramics Art Museum
The Ibaraki Ceramics Art Museum is a ceramics-dedicated museum located on the Kasama Craft Hill campus. In addition to a permanent collection tracing the history of kasama pottery, the museum holds regular exhibitions of contemporary ceramic artists’ work. Visiting before exploring the surrounding studios and markets helps build a fuller understanding of the tradition and depth of kasama ware.
The Openness That Draws Young Artists to Kasama
Another distinguishing quality of Kasama is the culture of acceptance toward outsiders.
In some Japanese pottery regions, technique passes from parent to child, generation to generation — a “succession model” that can make it difficult for newcomers from outside to establish themselves. Kasama has comparatively little of this closed character. Affordable land, an existing community of working artists, and a tradition of stylistic freedom — together these create a genuinely ideal environment for young potters considering a move out of the major cities.
The result is a ceramic community that is, by the standards of Japan’s kiln regions, unusually young and unusually diverse. Kasama feels not like a place preserving a tradition, but like a place where japanese ceramics is actively happening right now. That quality of living vitality may be Kasama’s most compelling attraction.
Finding the Kasama Pottery That Suits You
The most important thing when buying kasama pottery is simply this: find an artist whose work you respond to.
At the festivals and galleries, try asking the artist about their background and intentions before reaching for a piece. Hearing the story first changes what you see. Rather than buying “kasama ware” as a category, treat it as a chance to build a connection with a specific maker — that is the real pleasure of collecting kasama pottery.
In practical terms, kasama ware is particularly strong in everyday tableware (mugs, plates, bowls). Pieces that combine an artistic sensibility with genuine daily usability are everywhere here. For a first purchase, small pieces are a natural starting point. Then, gradually collecting more work by the artists you come to love — that is the most natural way to enter the world of kasama ware.
Getting to Kasama
Kasama City, Ibaraki Prefecture, is approximately 90 minutes from Tokyo by JR Mito Line to Kasama Station. Studios and galleries are spread throughout the area around the station, and both Kasama Inari Shrine and the Ibaraki Ceramics Art Museum are within walking distance.
Accommodation options in Kasama itself are limited, so day trips from Tokyo or Mito are most common. During the Himatsuri, early arrival is strongly recommended as crowds build quickly.
Beyond Tradition: Kawasumi Tomokazu, a Rising Ceramic Artist in Kasama
If Japan’s six ancient kilns, with their thousand years of tradition, are the unshakable root, then today’s Japanese ceramic scene is home to artists who have absorbed that tradition into their bones while opening entirely new possibilities in clay. One such artist — currently drawing intense attention in the Kasama region of Ibaraki Prefecture — is the young ceramicist Kawasumi Tomokazu.
Born in 1996, Kawasumi graduated from the Ibaraki Prefectural College of Ceramics, trained at the renowned Kasama studio Ōtsu Kō-gama, and established his own independent studio in 2023. His most distinctive quality is the metallic surface texture he achieves through a proprietary blend of Kasama clay and his own carefully controlled firing. At first glance the pieces look like heavy bronze or antique metalwork; touch one and the warmth that belongs to clay comes through. His work is widely praised as modern tableware that frames food beautifully.
He has also released bodies of work that step outside conventional ceramic categories: the Rock Bark series, where clay is carved and torch-treated to evoke rock face or tree bark, and the black-and-white Zebra series. His planters for caudex succulents, currently much in demand, have won an equally devoted following.
Kasama is described as a place whose defining feature is having no defining feature — and it is that acceptance of free expression that allowed Kawasumi’s philosophical world to flower. He is one of the artists who let you feel the living frontier of Japanese craft.
Kasama Ware Today and Tomorrow, Grown from a Culture of Freedom
Kasama ware continues to send out pieces that dissolve into contemporary life, with a freedom of expression unbound by tradition. This article introduced that tradition alongside Kawasumi Tomokazu, the young ceramic artist standing out at its leading edge. The appeal of kasama pottery lies in a culture that honours individual identity so completely that it is said to have “no defining feature” — and innovative work that resonates with contemporary art and interiors is born there every day.
Striking in form and yet possessed of a quiet luxury that lifts the food placed on it, this work quietly upgrades an ordinary table.
If Japan’s six ancient kilns, with a thousand years of history, are the unshakable root of Japanese ceramics, then kasama ware and Kawasumi’s work are the living frontier of Japanese craft — absorbing that tradition and opening the future.
Why not travel to Kasama in Ibaraki, breathe its free air, and look for the piece that speaks to you? A single piece carrying an artist’s conviction will bring something quietly richer into your daily life.
