Written By Hannah

The Okada kiln, Seiun-zan, is a Hagi-yaki workshop in Yamaguchi Prefecture, firing continuously since the Edo period. It is currently run by eighth generation potter Okada Yū, also written Okada Yutaka, alongside his son Yasushi. Yū is a designated holder of Yamaguchi Prefecture's Intangible Cultural Property for Hagi ware, recognised in 2006, known for ensai, a reddish, flame-like slip technique. Yasushi has developed tanseiyu, a pale blue glaze named after the Sea of Japan.

Traditional Japanese entrance gate and garden path leading to Okada Seiun-zan kiln, Hagi Yamaguchi — *The entrance to the Okada family home and workshop, Seiun-zan, in the Obata district of Hagi.*

Who runs the Okada kiln

The Okada kiln, known as Seiun-zan, traces its own line back to its founder, Okada Gonzaemon (岡田権左衛門), born in 1811 in Hizen Province before settling in the Obata district of Hagi to establish the kiln. The line continued through six further generations, Okada Heizaemon, Junsuke, Ryōsuke, and Senhachi among them, before passing to Okada Senshū, the seventh generation and father of the current head, born in 1916.

Okada Yū (岡田裕, also referred to as Okada Yutaka) was born in March 1946 in Yamaguchi Prefecture, where his father Senshū was posted at the time. He graduated in law from Keio University in 1968 and initially worked for the fishing company Kyokuyō, before the pull of Hagi-yaki led him to leave that career in 1972 and return home to train under his father. In 1976 he travelled to China to study ceramics. He was recognised at the Japan Traditional Crafts Exhibition from 1979 onward, received the Tabe Art Museum's award for tea ceremony forms in 1984, and was honoured with the Hagi City Cultural Encouragement Award (Sugimichi Prize) in 1988. In 1990 he became a full member of the Japan Craft Association. Following his father's death in 2004, he became the eighth generation head of the Okada kiln. In 2006 he was designated a holder of Yamaguchi Prefecture Intangible Cultural Property status, and in 2017 he received the Order of the Rising Sun.

His son, Okada Yasushi, works alongside him at the same kiln, in a workshop built around a noborigama climbing kiln that has fired continuously since the first generation, more than two hundred years ago.

What sets their work apart

Two distinct visual languages exist within the same workshop.

Okada Yū, ensai: a reddish, cloud-like slip applied before firing, developed from repeated research trips along the Silk Road. It produces a warm, flame-like bloom across a pale ground, ranging from a soft rust haze to a deeper, more mottled effect. This is his signature technique and the one most associated with the Okada name.
Yasushi, tanseiyu: a pale, clear blue glaze named after the Sea of Japan along the Hagi coastline. Cooler and quieter than ensai, it sits as a deliberate counterpoint within the same family workshop, the same clay handled in a completely different register.

The kiln

Seiun-zan has been firing in Hagi since the Edo period, and the workshop still carries that history in its bones. Anagama-style chambers built from brick and clay, stacked jars waiting their turn on the shelves, a noborigama climbing kiln that has fired generation after generation of the family's work. Nothing about it is staged for visitors. It is a working kiln, and it looks like one.

I spent a morning there watching two generations, father and son, move around each other in a space that has clearly held them both for years. → Read the full visit: Okada, a Hagi-yaki family kiln across three generations

How to recognise a genuine piece

Pieces are impressed with a circular seal reading 裕 (Yū), stamped into the clay of the footring before firing.
Signed works are often accompanied by their original tomobako, sometimes bearing a handwritten brush inscription of the same character above the seal on the lid, along with a shiori (descriptive booklet) issued by the kiln.
The shiori accompanying a piece will generally list Japan Craft Association membership, the Seiun-zan kiln name, and the Hagi workshop address (Maekobata, Hagi, Yamaguchi).

Hagi-yaki kogo shaped as Hotei laughing god signed Okada Yutaka warm white glaze with tomobako displayed on tatami mat next to whisk for size, Shōwa period Japan

Hagi-yaki kogo in the shape of Hotei, signed by Okada, with tomobako from 1970-1980

€235.00

Some objects are immediately recognizable for what they are. This one is. The moment you lift the lid, you know exactly who is sitting in your hands: Hotei, the laughing god of contentment, belly forward, expression completely at ease.

Produced at the Seiun-zan kiln in Hagi, Yamaguchi Prefecture, by Okada Yutaka: eighth-generation master of a kiln that has been firing continuously since the Edo period, and holder of the Yamaguchi Prefecture designation for Intangible Cultural Property in Hagi-yaki.

This is not a decorative object made for the tourist market. It is a serious tea ceremony piece with full provenance.

There's a whole philosophy behind why a kogo is left open after use. Read it in my journal.

Hariya Yūsai's black lacquered natsume tea caddy with gold and red crests, a bamboo whisk, and its signed tomobako with a blue ribbon, on a rustic wood slab.

Lacquered Kōdaiji makie natsume tea caddy with gold and red chrysanthemum and paulownia crests, signed by Yūsai, tomobako

€245.00

Black so deep it looks like still water, and scattered across it, crests in gold and in red, none of them quite where you expect. The gold ones are soft and matte, while the red ones carry tiny flecks of gold that wake up when you turn the lid toward the light. It sits in the palm like a smooth pebble and is hard to put down. It is the kind of small object that makes a shelf, a desk or a tea tray look considered.

It was made by Hariya Yūsai, a makie artist from Ishikawa who is recognised in Japan as a Traditional Craftsman, and he signed and sealed the wooden box himself. That box is why it feels complete: the natsume, the box that names its maker and its style, and the yellow cloth that came with it have stayed together. If you make matcha, this is a proper tea caddy with a real maker behind it. If you don't, it is still something you will want to keep in sight.

Black lacquered tea caddy with engraved vermilion peony design, bamboo whisk, and wooden box signed Fujiwara Seiu, on a textured wood surface.

Lacquered tea caddy with engraved vermilion peony, signed Fujiwara Seiu, with tomobako

€210.00

Turn it toward the light and the red changes. What looks like a deep, dark red on black shifts to a brighter red with a hint of pink, and the blossoms on the lid and body turn delicate rather than graphic. It is a small, rounded caddy with flowers drawn right across it, and with every tilt you notice a different one. It is the kind of object you pick up to look at and end up turning in your hands.

The lacquer is glossy and smooth. Run a fingertip over the flowers and in places you can feel the cuts through the lacquer, fine lines that sit in the surface rather than on top. At approx. 54 g the natsume is light in the palm, small and rounded.

Shino chawan, signed, Mino tradition with original tomobako

€255.00

Pick this bowl up and it surprises you: for something this size, it settles low and steady in your hands, the thick walls giving it a grounded weight rather than a fragile one. The rim moves in its own irregular line, never quite a perfect circle, so no two angles look the same. White glaze breaks into rust-orange blush along one side like scorch marks, and it is easy to imagine how matcha would sit inside it, pooling green against that warm white and orange, exactly the kind of contrast tea practitioners seek out a bowl for.

What makes this one worth taking home rather than admiring from a distance is that it comes whole: the original tomobako, signed and sealed, and the silk wrapping cloth that carried it, stamped with the same seal as the box. Pieces where the box, cloth and bowl are still this clearly matched to each other carry a quiet kind of proof in themselves.

Katō Shōzan's Oni-Shino chawan, rustic white with rust brown speckles and textured walls, alongside a bamboo whisk and scoop on a green tatami mat.

Oni-Shino winter chawan signed by Katō Shōzan, Enshō-gama, Mino ware

€235.00

It is the snow white and the specks sprinkled all over along with the shaped outer wall that catches the eye. The walls of this bowl have been pressed inward all the way around, leaving a ring of shallow hollows that sit exactly where your fingers want to go. Rust brown flecks and drips gather in those hollows and trail down from the rim through a thick, white glaze, so the decoration follows the movement of the hand that shaped it. It is a sturdy, generous bowl, made to be held rather than admired from a distance.

It was made by Katō Shōzan at the Enshō-gama kiln in Oroshi, a pottery district of Toki in the Mino region of Gifu, the region where Shino ware was born in the late sixteenth century. The kiln's own printed leaflet speaks of carrying forward the techniques handed down from the founders of Mino pottery. This is an oni-Shino chawan, iron beneath feldspar glaze, signed by hand with 正山 scratched into the clay of the base: a working tea bowl from a working kiln, ready to be used every day.

Onta-yaki matcha chawan from the Kobukuro kiln, signed 鹿峰 Rokuhō, with tomobako and shiori

€255.00

Held up to the light, this bowl is not black at all. The glaze is a deep brown that reads almost black at first glance, and over it runs a blue that settles in patches inside and out, pooling thickly before it stops at a clean line of bare clay around the foot. On the table it is dark and quiet; in your hands, turned toward a window, it becomes warm and layered.

It was made at the Kobukuro kiln in Onta, one of nine family workshops in a small mountain village in Ōita Prefecture that has made folk pottery in much the same way for about three centuries. Onta potters traditionally leave their work unsigned, and they mostly make plates, jars and rice bowls for everyday use rather than bowls for tea.

It is dated to Shōwa 47 (1972) and signed by its maker, Rokuhō (鹿峰), on its foot and on its original wooden box.

Two Maruta Nobumasa Kuromuta-yaki bowls, inverted on wood, showing speckled clay with white drips, black strokes, and wine-red glaze patches.

Two hira-chawan, shallow Kuromuta-yaki tea bowls from the Maruta Nobumasa kiln with tomobako

€235.00

A milky white glaze drips from the rim of both bowls, as if each one had been dipped upside down and left to run before the fire. Beneath it, thick strokes of near black glaze stop and pool like brush marks, and patches of wine red seem to glow from inside the glaze itself. The clay underneath is pale grey, freckled with iron, so everything painted on it sits like ink on paper.

Wide and shallow, the two bowls side by side are clearly siblings rather than twins: no two strokes fall in quite the same place.

They come from the Maruta Nobumasa kiln in Takeo, the last working kiln in Kuromuta, a mountain village that once counted around forty. The kiln's founder, who set up on his own in 1961, chose to make ware for daily use rather than for exhibition, and these bowls still feel like they want to be picked up. They arrive with their original tomobako, hand inscribed and carrying the kiln's red seal.

Nagasawa Minoru, Izushi-gama chawan with a soft grey-blue crackled glaze and pink blush visible in the interior, on a wooden surface.

Izushi ware chawan by Nagasawa Minoru, Izushi-gama, signed tomobako, Hagi style, Shōwa period

€255.00

Pick this bowl up and the shape answers a question before you ask it. One side of the rim sits straighter than the rest, a shallow, deliberate press into the wall that meets your fingers exactly where a hand naturally rests. The glaze is a soft grey-blue, smooth under the fingertips, and where it catches the light around scattered pinholes a faint pink blush shows through, the same warm pink that spreads openly across the whole interior. Fine crackle runs over every surface, the kind that only comes from decades of tea passing through it.

This bowl carries the signature of Nagasawa Minoru, third generation head of Izushi-gama, the Nagasawa family workshop that has worked in Izushi, Hyōgo Prefecture, since 1907. Minoru trained at the Kyoto Municipal Ceramics Training Institute before turning to painting under Akamatsu Unrei in Osaka, and went on to win the Hokuto Prize at the Nitten exhibition, serve as a Nitten judge, and receive Japan's National Yellow Ribbon Medal in 1974. Izushi-gama is best known for pure white porcelain, but Minoru was the generation who also worked in local clay, and this bowl, with its Hagi-like crackle and blush, is a rare piece of evidence of that side of his work.

Those small pinholes in the glaze aren't unique to Hagi and Shino wares alone. Curious what causes them, and why tea masters have prized them for centuries? Read more about su-ana, the "nest holes" of Japanese glaze here.

Tall red raku style tsutsu chawan with white drip glaze, Hioki Nanshū kiln, late Shōwa

€95.00

A tall, straight sided tsutsu shape bowl the colour of terracotta after rain, standing on a small foot as if lifted. Cream marks cross the surface like quick brushstrokes, and on one side a white glaze runs down from the rim and fades halfway. It is as high as it is wide, about 10 cm each way, so it fills both hands the way a winter tea bowl should.

It comes in a box stamped and sealed by the Hioki Nanshū kiln in Kagoshima. The kiln is still active today, on the site of the Daijō-ji, the family temple of the Hioki Shimazu family.

Tsutsu chawan with turquoise and grey crackle glaze, beside a wooden tomobako with Tsuchiya Issui inscription and a yellow ribbon, on a rustic wooden stand.

Unavailable

(sold) Hand thrown winter tsutsu chawan with layered turquoise and grey glaze, wooden box included

€90.00

Tall and straight-walled, this tsutsu shaped chawan holds its heat the way it holds attention, a shape traditionally reached for in the colder months. It hols a substantial, satisfying weight in the hand. The glaze pools into a clear turquoise on one side, breaking into a soft, speckled grey field, with warm brown lines tracing all over the body. It is a bowl that draws the eye before it ever reaches your hands.

This chawan comes with a wooden tomobako inscribed with the name of a Hagi-yaki maker. The glaze and form of the bowl itself are not typical of Hagi-yaki, so I can't confirm this is its original box. Japan has an enormous number of studio potters, each with their own variations, so I'm not ruling it out either. The box reads: Tsuchiya Issui (土屋一翠), 12th generation, Hongama kiln (main/head kiln) and Hagi-yaki. Either way, it's a genuine wooden box and comes included. It keeps the cup safe in your home.

Mizushima Jirō chawan, textured blue-speckled grey glaze, leaning on wood to reveal its tan unglazed foot. Bamboo whisk nearby.

Kagurao-yaki blue chawan by Mizushima Jirō, Denjirōbō kiln, with tomobako and shiori

€215.00

The glaze is what stops you first: smooth under the light, dense with fine blue speckling that seems to change as you turn the bowl, flaring brighter in some angles and settling quieter in others. Run a finger across the surface and it glides.

This bowl comes from a kiln you will not find in any reference book. Mizushima Jirō built it himself at the foot of Kagurao, a hill near an old castle ruin outside Tsuyama, in Okayama Prefecture, and named the ware after the mountain itself.

The ruin belonged to Kagurao Castle, a hilltop fortress whose founding date is undated but which stood active through the Muromachi period, into the late sixteenth century. In his own handwritten shiori, he describes using local clay and firing with red pine, the same wood traditionally used to fire Bizen ware in the same prefecture, chasing a glaze effect he calls a "unique melting field," one he admits he was still trying to master.

He called his own work raku-yaki, and the bowl itself, dense, high fired stoneware with a hard, unglazed foot, tells a story closer to a personal, self-taught practice than to the soft, low fired tradition the word usually points to. Owning this piece means owning one individual potter's own account of his materials and process, in his own hand, with nothing added or assumed beyond it.

Irregularly shaped Sangiri Bizen chawan by Inomata Masaaki, showing unglazed rust, orange, ash grey, and silver tones, on a tatami mat next to its signed wooden box.

Sangiri Bizen chawan signed by Inomata Masaaki, Dentō Kōgeishi late Shōwa to Heisei period

€195.00

The clay tells you everything before you even touch it. One side has gone the colour of embers still holding heat, deep rust and burnt orange bleeding into ash grey where the flames never quite reached, and across the rim that grey turns almost silver, dusted like the first frost on a window. No glaze was ever applied here. Every mark, every shift in tone, is the direct signature of ten days or more inside a wood fired kiln, clay and flame negotiating the surface between them.

This bowl carries the seal of Inomata Masaaki, a Bizen potter based at the Saizōbō kiln in Okayama prefecture and one of the region's certified Dentō Kōgeishi, a formally recognised Traditional Craftsman title awarded by the prefecture. He built his own climbing kiln and became independent in 1975, after training under a respected Bizen workshop, and has spent the decades since inside a tradition that dates back over a thousand years to Japan's oldest surviving pottery kilns. A chawan carrying his signature is not a stylistic guess. It is a documented piece from a working master within one of the Six Ancient Kilns of Japan.

Bizen-yaki guinomi with sangiri firing marks, signed Yamamoto Sōshū, Bishū-gama kiln, late Shōwa to Heisei period

€95.00

Held up to the light, this cup shows the fire's full range in one small object. Deep aubergine and charcoal dominate the body, and across it runs a bold band of red and gold, the mark of ash settling directly against the clay during the long firing. Toward the base, the tone cools into silvery grey. Nothing about this colour was painted on. It is the direct record of where the piece sat inside the kiln.

The rim is uneven in the way a hand-thrown piece always is, tipping just slightly to one side. It is small enough to sit fully inside one closed hand, the kind of size that asks to be picked up rather than looked at from a shelf.

This cup carries the signature of Yamamoto Sōshū, the kiln name under which Bishū-gama in Imbe has worked since 1974. The kiln was founded on the initiative of Living National Treasure Yamamoto Tōshū for his eldest son and daughter-in-law, and it has built its reputation specifically on hidasuki fired this clean and this legible. It comes still complete with its original tomobako and shiori, exactly as it left the kiln.

Front view of two Shibaoka Tōsendō Bizen-yaki tokkuri vases on a tatami mat with silvery-blue and reddish-brown firing marks.

Pair of Bizen-yaki tokkuri vases, Shibaoka Tōsendō, Kōzan-gama kiln, Imbe

€85.00

Two small teardrop vases, narrow at the neck and full through the shoulder, standing close enough together that they read as a pair without being identical. One leans toward deep aubergine with a soft silver mist rolling across the front, almost metallic where the light catches it. The other runs cooler still, a wash of silvery blue-grey shifting into warm rust low on the body. Neither would look complete alone. Together they hold a conversation, one leaning warm, the other leaning bright.

Both carry the maker's mark of Shibaoka Tōsendō, working under the kiln name Kōzan-gama in Imbe since 1912. The kiln has stayed in one family for three generations, currently the third-generation Kōzan, Shibaoka Masashi, working alongside his sons Chikara and Hisashi. A pair like this, thrown at the same time and fired side by side in the same noborigama, is a small, physical record of one firing at a kiln that has kept its own fire burning for over a century.

White glaze chawan with blue ice crackle and iron oxide glaze flow, signed Sansōan with tomobako

€185.00

The glaze on this one shifts from a pale, crackled blue-grey into a deep, warm rust-brown that spills down one whole side like something poured rather than painted. Streaks of ochre yellow brown run through the transition, and the unglazed foot beneath it all is a rich, earthy red-brown, left bare so the clay can speak for itself.

This chawan comes with its original tomobako, signed and sealed 山桑庵 (Sansōan), a studio potter’s workshop name. It has the kind of glaze variation that rewards turning it slowly in the hand before you drink from it.

Notice: This chawan has found a new home. If you are looking for something similar, please let me know. As I list in small batches, so there may be more in stock than you currently see.

And if I do not have it yet, I source in Japan a few times a year and am always happy to keep an eye out for you specifically.

There is a moment, turning this bowl slowly for the first time, where you stop trusting your own eyes. From one side, the glaze looks almost calm, a pale, crackled white. Look closer and that white is covered edge to edge in a fine web of cracks, catching the light like a cracked windshield. Turn it a few degrees and that same surface has turned to rust, deep orange bleeding into near black at the rim. Then you tip it, and the inside pools into a deep, mossy green touched with gold, a colour neither side of the outside ever hints at. Somewhere along the thick, generous rim sits a small patch that has turned an unexplained grey-blue, rougher under the thumb than the glaze around it. This is not a bowl that settled on one thing.

This chawan was made at the Kakuzan-gama in Ayabe, a kiln built in 1959 at the headquarters of the Ōmoto religious organisation, and it is signed by Deguchi Eiji, who married into the family that founded Ōmoto and served as its Sōchō, its director, from 1958 to 1962. He was not a professional potter by trade. He was someone close to the centre of a movement that treated making things by hand as part of its own philosophy, working in an ash-glaze tradition brought to the kiln by its founder, the Bizen master Kaneshige Sozan. This bowl is what that looked like when it left his hands. A signed, boxed chawan from a maker with this kind of documented history rarely surfaces outside Japan.

Turn this chawan and the surface answers differently every time. A rough, ash-textured grey-green skin gives way, near the rim, to a pool of deep crackled jade, the kind of colour you notice from across a room before you notice anything else about the piece. The clay shows through at three small unglazed spots on the interior where kiln supports once held it during firing, tiny, honest proof of exactly how this bowl was made.

This chawan made by Ishihara Shōji, a Fukuoka Prefecture ceramic artist born in 1943, who trained as a sculptor before turning to ceramics and building his own kiln in 1981. Ash-glazed, unglazed stoneware work like this belongs to his early period, before the distinctive coloured Oborodeisai style that made him widely known from 1989 onward. A documented early piece by an artist now represented by galleries in New York and across Japan.

Hagi-yaki natsu-jawan matcha bowl beside signed tomobako wooden box, tatami mat, ukiyoe print background, Japan

Unavailable

(sold) Hagi-yaki summer chawan with karahai glow, signed by Matsuura Mugen, Shōwa period

€325.00

Notice: This chawan has found a new home. If you are looking for something similar, scroll down.

Held at an angle, this chawan catches the light differently every time. The pale, crackled glaze runs from a soft off-white into a warm, almost blush pink where it thins over the clay, a color Hagi potters call karahai, and it only appears where the firing has gone exactly right. The rim tilts and dips ever so slightly, a wall that never quite settles into a perfect circle, and that small imperfection is what makes it sit so naturally in the hand. It is a bowl built to be picked up, turned, and looked at again.

This bowl carries the tomobako signature of Matsuura Mugen, founder of the Shōunzan-gama kiln in Hagi, built on the very ground where Hagi-yaki itself began centuries ago. Mugen's work grew out of the tradition of Miwa Kyūwa, one of the defining masters of Hagi ware and a holder of Japan's Living National Treasure designation, and that lineage shows in the quiet, unforced warmth of this glaze. Its wide, shallow shape is a natsu-jawan, a summer bowl, made so the tea cools a little faster in the warmer months, which makes this the moment to bring it into use rather than let it wait. A signed, boxed chawan from this kiln is not something that turns up often outside Japan.

Inuyama-yaki chawan by Kujiro with original tomobako box and shiori, matsukawa bark glaze tea bowl

Inuyama-yaki matsukawa glazed chawan by signed by Osawa Kujiro Toen with tomobako Shōwa period

€255.00

The glaze does the talking before anything else does. Uneven brown breaks across the exterior like bark peeling off a trunk, dark where it pools thick, almost gold where it thins, smooth and glossy to the touch despite all that movement. Turn the bowl in your hands and the surface catches the light differently every few centimetres. Inside, all of that noise drops away: a quiet grey-green settles at the base, still and cool against the storm outside.

This bark-textured glaze, matsukawa-yaki, has its own story. It was developed at a small kiln in Inuyama, Aichi Prefecture, now known simply as Matsukawa-gama after the technique that made it locally famous. The kiln has worked continuously for over a century, and this particular glaze earned its reputation the slow way: refined over two generations and shown at exhibitions across Japan until the public gave the workshop its name.

Shino-yaki chawan, carved glaze pattern, Han'emon-gama kiln Mino Japan

Shino-yaki chawan by Katō, Han'emon-gama kiln, with tomobako and shiori Shōwa period

€255.00

The glaze moves across this bowl like weather crossing a landscape, white where it lies thick, sliding into a soft blue grey where it thins, with a line of warm rust colored fire blush running unevenly along the rim where the clay broke through during firing. A carved geometric pattern circles the exterior, cut through the dark iron ground before the glaze was applied, so the pale clay shows through in a repeating motif that catches the light differently depending on where you stand. Small dark specks surface throughout the glaze, scattered without any pattern, the kind of detail that only shows itself once you start looking closely.

This bowl comes from the hands of the Katō family from their Han'emon-gama, a kiln in the Mino region of Gifu Prefecture whose own written history traces its family back through generations of potters working in the Shino tradition, one of the oldest white glaze traditions in Japanese ceramics and still closely tied to the tea ceremony today. The piece is signed with the kiln's stamp on the foot, and it comes with its original tomobako and an accompanying document that lays out the family's own account of its lineage. Owning it means owning a small, physical piece of that continuity.

Bizen-yaki tokkuri by Isezaki Sō on its wrapping cloth, front view showing the olive to aubergine ash glaze

Bizen-yaki tokkuri signed by Isezaki Sō, original tomobako

€180.00

There is a quiet violence to how this tokkuri came out of the kiln. No glaze was ever applied, everything you see, the deep olive shoulder, the passages of smoky grey, the flush of aubergine low on the body, happened because ash and flame found this exact spot in the kiln and nowhere else. The form is rounded and a little heavy in the middle, the neck flares just enough to pour cleanly, and it sits with the kind of quiet confidence that unglazed stoneware only earns after firing for days.

This comes from Isezaki Sō, born into one of the defining pottery families of Bizen and a full member of the Nihon Kōgeikai, the Japan Craft Association, since 2004. He trained under Yamashita Jōji from 1987 and has spent the decades since collecting awards at the Nihon Dentō Kōgei-ten and the regional Chūgoku exhibitions that matter most within the tradition. Owning this is owning a piece from someone who has spent a working lifetime answering to that lineage, not performing it.

No glaze, no paint, just fire. I wrote about how Bizen gets its color, in my journal.

(sold) Kuro chawan with carved cherry blossom, signed by Okugawa Katsuomi with tomobako, late Shōwa period

€235.00

Notice: This chawan has found a new home. If you are looking for something similar, scroll down.

Nearly the entire surface disappears into black, a glaze so deep it seems to swallow the light around it. Then, sweeping across one side, a pale arc of ash white clay breaks through, and from that ground three cherry blossom branches rise. The blossoms are carved into the clay itself, the branches traced in warm gold. The bowl is compact, a little heavier than it looks, and it settles into two cupped hands as though it were made for exactly this grip.

Okugawa Katsuomi built his reputation the hard way, striking out on his own rather than working under an established kiln name, and the confidence in this piece shows why that risk paid off. A potter working independently answers to no house style, only to his own hand, and a cherry blossom cut this precisely into a glaze this dark is the kind of detail that gets noticed. This bowl comes with its full history attached, both in the tomobako it still carries and in a maker whose name is now well documented.

Ao-Oribe chawan with painted figures and vine scrollwork, Mino ware from Shōwa period

from €110.00

The first thing you notice is the collision of opposites. On one face, bold dark figures stride across a cream ground in a repeating procession, painted with the kind of confidence that does not hesitate. Turn the bowl and the motif shifts entirely: a scrolling vine arabesque in the same iron brushwork, curling and looping across the surface. Then the green glaze interrupts everything. It tips over the rim from both sides, drips down the wall, and floods the interior with a deep copper-green that shifts toward teal where it pools thickest. The form does not behave either: the rim is uneven, the walls slightly irregular, the whole shape carrying a deliberate looseness that makes it feel alive in the hand.

This is a chawan in the Ao-Oribe tradition, one of the most irreverent ceramic styles Japan produced. From the Mino region of Gifu Prefecture, Ao-Oribe takes its name from tea master Furuta Oribe (古田織部), whose aesthetic philosophy embraced asymmetry, bold brushwork, and what he called hyōge: a spirit of wit and ease. A bowl made in this tradition was never meant to be precious. It was made to be picked up without ceremony, to improve with handling, and to grow more interesting the longer it is used.

E-Karatsu kōgō with painted plum branch signed Inoue Koji with original tomobako and shiori documentation Japan displayed on tatami mat, lid open with incense inside

E-Karatsu kōgō with plum branch, signed by Inoue Koji, with original tomobako box and shiori documentation

€385.00

This is not a commercial production but a purpose-made ceremonial gift from the heart of the Japanese tea world.

The gift itself is an e-Karatsu kōgō, an incense container for use in the tea ceremony, made specifically for this occasion by Inoue Koji of the Kyōzan-gama in Karatsu.

This kōgō was never for sale. It was made to be given: a ceremonial gift commissioned by the headquarters of the Urasenke Tankōkai in Kyoto to mark a recipient's 88th birthday, the milestone the Japanese call beiju. The letter that accompanies it states that the gift comes from Zabōsai, the 16th generation iemoto of Urasenke, the living guardian of one of the three great tea lineages descending directly from Sen no Rikyū.

What you are looking at is not a commercial production. It is a document of the tea world in use.

Shira-hagi chawan Taizan kiln white Hagi ware matcha bowl displayed on wooden plank with original tomobako, Shōwa period ca. 1960 to 1975 Japan, ukiyoe print in background

Shira-hagi chawan, Taizan kiln, white Hagi ware matcha bowl, original tomobako, Shōwa period, ca. 1960 to 1975

€255.00

This bowl has a way of looking complete from any angle. The form is low and wide, the rim gently uneven in the way of something made by hand rather than adjusted toward perfection.

The glaze is a full, dense shining white over most of the body, with orange pushing through directly where the clay asserts itself. It stops you before you know why.

This chawan comes from an earlier generation of Taizan-gama, one of the kilns that has worked in the Tsubaki district of Hagi within a tradition tea masters have placed second only to Raku for four centuries.

The tomobako is inscribed 白萩茶碗 and the bowl carries the full rectangular 泰山 seal, the older mark of the kiln used before the oven was incorporated as a company.

Bizen Yakishime chawan named Tekifu with budō-iro fire effect, signed by Gekifūsei with original wooden tomobako, late Shōwa period

€285.00

The first time I held this bowl, I turned it slowly in both hands and tried to work out what I was looking at. Purple, deep crimson, ashy grey, a band of pale white on the inside where the heat had settled differently. None of it looked applied. It looked like something that had happened to the clay rather than something done to it.

That is, more or less, exactly what yakishime is.

Yakishime is the practice of placing unglazed clay in a wood-fired kiln and letting the fire decide the rest. In the Bizen tradition this has been practiced for over a thousand years, and the surfaces it produces, rough clay, fire-born colour, marks that record the firing like a landscape, became one of the foundations of Japanese tea ceremony aesthetics. A bowl made this way was not decorated. It was shaped, placed in a kiln, and submitted to fire.
