Bizen Pottery History: 1,200 Years from Sueki to the Tea Bowl
The history of bizen pottery is usually compressed into a single line: “Japan’s oldest pottery, more than a thousand years old.” Inside that line sit the techniques carried over by immigrant craftsmen, the quotas set by the imperial court, the shift from reduction to oxidation firing, and the aesthetic that tea masters discovered — layer upon layer of history, arriving at the japanese ceramics we hold today.
This article takes the history outlined in Bizen Ware: The Famous Pottery Born from the Six Ancient Kilns — Earth and Flame and goes deeper, period by period, from the age of sueki stoneware to the stagnation of the late Edo era. Why did bizen pottery become red, and why does it draw its beauty from having no glaze at all? Let us take the reasons one at a time.
Bizen Pottery Began with Sueki Stoneware
The direct ancestor of bizen pottery is sueki (須恵器, grey stoneware).
The Jomon and Yayoi earthenware that came before it was hand-formed and fired at low temperature, and it leaked. Sueki was different: thrown on a wheel and fired hot in a tunnel kiln under reduction, producing a hard, grey stoneware. Strong, and watertight. The people who brought this technology to Japan were engineers who crossed from the Korean Peninsula.
Arriving with them was Rokuro seikei (wheel throwing). Jomon and Yayoi pottery-making had been Tebineri — hand-building, and women’s work — but from the introduction of the wheel onward, sueki production shifted to become a specialised male occupation. When the technique changed, the makers themselves changed with it, and the first step of the history leading to today’s bizen pottery was taken.
Alongside it, hajiki (土師器) — descended from Yayoi earthenware — continued in wide use. Soft, reddish-brown, fired in oxidation, it served everyday cooking and ritual.
Immigrants Settled in Okayama, and Bizen Became a Production Centre
Around the year 400, people from the kingdom of Baekje on the Korean Peninsula were naturalised in Japan, and some of them settled in what is now Okayama Prefecture. This is how sueki technology took root in Bizen. Because the hajiki potters migrated at the same time, Okayama of that era became a densely populated region.
Sueki and hajiki production at the time was administered from the centre — the capital at Kyoto. Bizen was positioned as one of its production bases. And in the Engishiki (延喜式), the code of law compiled in 901, Bizen was assigned the largest delivery quota of all.
Being able to fire that many pieces meant there were kilns, there was clay, and there were people. That accumulation became the foundation on which bizen pottery would later survive as one of the Six Ancient Kilns.
For what was happening in other kiln regions during the same centuries, read The History of Japanese Ceramics together with Japan’s Six Ancient Kilns: the Country’s Oldest Pottery Regions.
Hard Years: The Rise of Lacquerware
But once the age of the samurai began (from the late twelfth century), this system of central control lost its power. Makers who had survived simply by delivering a fixed quota lost their backing.
What followed was harder still: the rise of lacquerware. Light, unbreakable and well suited to soup, lacquer pieces spread widely, and demand for sueki and hajiki themselves contracted. As Japanese Lacquerware Guide: How Urushi Brings Wood to Life shows, lacquerware was, for its time, an overwhelmingly advanced option.
Potters had to find a way of living that was not the life of a potter. The history of bizen pottery begins with standing up again from this crisis.
From Nara to Heian: Earthenware Becomes Pottery
Pottery began to be fired in Bizen itself roughly 1,200 years ago, in the Nara period (710–794). The shift from earthenware to pottery came in the Heian period (794–1185). By then the two lineages — sueki and hajiki — had merged technically.
What separates earthenware from pottery is whether glaze is applied and the firing temperature.
| Type | Glaze | Firing temperature |
|---|---|---|
| Earthenware | None (unglazed) | Low |
| Pottery | Applied | High, fired dense |
Bizen, however, does not sit neatly in this scheme. Bizen chose to stay unglazed and fire hot instead. This principle is called Yakishime (unglazed fired ware), and it is the idea inherited from sueki, carried on unchanged. The full classification is set out in Japanese Pottery: Earthenware, Stoneware and Porcelain Explained.
Note that the small unglazed earthenware cups and dishes used from the medieval into the early modern period are called kawarake (カワラケ), and were treated as a separate lineage from Bizen’s unglazed high-fired work.
Late Heian: Why Bizen Turned Red
Here lies the decisive turning point in the history of bizen pottery, and the one most often overlooked.
Sueki up to this point had been reduction-fired — starved of oxygen inside the kiln. Iron in the clay develops black, and the piece comes out grey. But by the late Heian period, red pottery was what people wanted.
So Bizen switched to oxidation firing, increasing the burn and firing harder. Send in enough oxygen and the iron in the clay develops red. What emerged from this was the reddish-brown that belongs to Bizen alone.
The colour we picture today when we hear the words bizen pottery is the result of that shift in demand, and of the change in firing that answered it. How to read the colours and markings that appear on the surface is covered in Japanese Pottery Keshiki: How to Read Glaze Drips, Flame Marks, and Kiln Effects.
Bizen Alone Changed Its Kiln Early
From the sueki era onward, Bizen and every other region used the Anagama kiln — a tunnel dug into a hillside on the slope, large enough for an adult to enter stooping, pitched along the incline.
But Bizen was the first among the Six Ancient Kilns to take a new option. While the other regions kept using tunnel kilns until the Muromachi period (1336–1573), Bizen moved early to the semi-above-ground kiln, the so-called teppō-gama (鉄砲窯). Its structure: a trench dug into a natural slope, roofed over with an arched vault.
Afterwards, as the other regions developed from the Muromachi period onward, Bizen’s kiln was left holding the oldest form of all. By keeping that old form, Bizen preserved its own history intact, and carried it into the present day.
How the structure of a kiln moves flame and ash, and decides the expression of a piece, can be read in Wood Fired Pottery: The Art of Japan’s Noborigama Climbing Kiln and Noborigama kiln.
Kamakura to Muromachi: What Was Being Fired
Kamakura Period (1185–1333) — Jars, Urns, and the Grinding Bowl
What Bizen fired in the Kamakura period was jars and storage urns. And the piece for which demand in Bizen ran especially high was the suribachi (摺鉢, grinding bowl). Bizen clay, fired hard and dense, resists wear under grinding. Here a practical requirement became the region’s speciality outright.
Pieces from this period begin to show the wood-ash glaze called goma (胡麻, sesame). Ash from the firewood settles on the piece, melts at high temperature and turns to glass, sometimes leaving trails as though glaze had run. Because no one applied it by hand, it is called Shizen-yu, natural ash glaze.
Muromachi Period — Tea-Leaf Jars, and the Chinese Wall
In the Muromachi period, tea-leaf storage jars began to be fired. In this field, though, the highly practical Chinese imports were prized, and Bizen never took the leading role.
The current turned in the mid-Muromachi, as the Sengoku era of warring states began. Tokkuri sake flasks and similar pieces came to be fired, and with the spread of wabi-cha — the austere style of tea — Bizen began producing tea ceramics too. Not lavish Chinese imports, but beauty found in the raw texture of clay itself; this inversion of values pushed Bizen onto the main stage.
What the tea ceremony brought to japanese pottery is covered in detail in Japanese Tea Ceremony Ceramics: & History and What Wabi-Sabi Ceramics Bring Into our Life.
Late Muromachi — Guilds and the Shared Kiln
In the late Muromachi, Bizen’s makers organised into za (座, trade guilds). Kilns moved from individual ownership to the shared kiln — a system in which one kiln was divided and fired between them.
Sharing a kiln means that how the flame strikes a piece, and how the ash falls on it, is decided by where it stands. Bizen’s “landscape that never repeats” is born partly from the structure of that shared kiln.
Momoyama Period (1573–1600) — Tea Masters Chose Bizen
In the Momoyama period, Bizen came to be loved by tea masters more than ever. The piece used most of all was the kensui (建水, waste-water bowl). Flower containers had been known as celebrated pieces even before this, and spread further in this era.
At a tea gathering, the kensui is the piece into which used hot water is discarded. To choose a raw, unrefined clay piece for the least conspicuous utensil of all — that choice was itself the Momoyama aesthetic.
For a comparison with a region that aimed at the same austerity by the exact opposite method, Hagi Ware and Bizen Pottery: Two Philosophies of Wabi-Sabi in Japanese Ceramics is the clearest place to look.
Edo Period (1603–1868) — The Age of Sculptural Work, and Then Stagnation
With the Edo period, Bizen’s mainstream changed. Three-dimensional sculptural figures took the centre, and incense containers and similar pieces were fired in quantity. It was an era in which the skill of carving clay and building form was refined.
But in the late Edo, sales stagnated under pressure from Imari and Seto porcelain. White, thin, and able to carry painted decoration, porcelain was a new option for the people of the day.
Within that, Bizen’s production system had no choice but to change as well. Until then the cycle had been large in scale — a shared kiln fired for thirty to forty days, opened once a year — and this shifted toward the present-day arrangement of small groups of makers opening the kiln more frequently.
Receiving 1,200 Years in a Single Piece
So it is that bizen pottery, while inheriting its history from the past, came through crisis by changing its kiln and its firing method on its own terms, and arrived here. Follow the history of bizen pottery and you notice that this region has never once had a period of stability. Cut loose from state administration, pressed by lacquerware, pressed by porcelain — and each time it changed what it fired. From jars to grinding bowls, to tea ceramics, to sculptural work.
Even so, one thing never changed. The choice of Yakishime (unglazed fired ware), applying no glaze at all.
The principle carried in by immigrant craftsmen 1,500 years ago — fire it hot enough and it will hold water without glaze. From there to now. The hidasuki plate in your hand, the guinomi sake cup with goma running across it: both stand on that principle, and that is the appeal of bizen pottery still being fired today. Why not bring a piece with 1,200 years of history behind it into your own daily life?

備前焼はいつから始まったのですか？
土器から陶器へと移行したのは平安時代で、この頃には須恵器と土師器という二つの系譜が技術的に合流していました。
備前焼はなぜ赤褐色なのですか？
ところが平安末期に赤色の焼き物が求められるようになり、備前は燃焼力を増して酸素を十分に送り込む焼き方へ移行します。酸化焼成では土の鉄分が赤く発色するため、備前特有の赤褐色が生まれました。需要の変化が、焼き方そのものを変えた例です。
備前焼の表面にある独特な模様（景色）にはどんな種類がありますか？
緋襷（ひだすき）：器に稲藁（わら）を巻いて焼くことで、藁の成分が反応して現れる鮮やかな赤橙色の線。
胡麻（ごま）：燃料である松の薪の灰が高温で溶け、器の表面にゴマを振りかけたように付着して緑〜茶色のガラス質になったもの。
桟切り（さんぎり）：窯の中で酸素が不足する「還元焼成」が起きることで、器の一部が青〜黒色に劇的に変化したもの。
牡丹餅（ぼたもち）：窯詰めの際に器同士を重ねた箇所が火に当たらず、丸い牡丹餅のような形で残った焼きムラの痕。
「備前焼で飲むとお酒や水が美味しくなる」と言われるのはなぜですか？
お酒がまろやかになる：釉薬がかかっていない多孔質の素地には目に見えない微細な気孔があり、これが微量の酸素を通すことで、日本酒やウイスキーなどの角（カド）を取り、味をまろやかにすると言われています。千利休も「備前の酒器は世界一」と絶賛したと伝わります。
水が腐りにくく、花が長持ちする：微細な穴が内部の環境を適度に保つため、「呼吸する器」として水の腐敗を防ぎます。そのため、備前焼の花器に生けた切り花は驚くほど長持ちすることで知られています。
備前焼の「器を育てる」とはどういう意味ですか？
一般的な磁器は使っても見た目が変わりませんが、無釉（むゆう）の備前焼は、毎日使うことで手の油分やお茶、お酒が少しずつ素地に染み込んでいきます。最初は無骨でザラザラしていた質感も、10年、20年と使い続けることで、しっとりとした独特の光沢を帯び、持ち主の手に馴染む滑らかさへと変化します。この「自分だけの器にしていく経年変化」こそが、海外の愛好家からも絶賛される備前焼の最大の醍醐味です。
