Raku Ware (楽焼): The First Bowl of Chanoyu

There is a saying in the world of chanoyu: 一楽二萩三唐津. Ichi Raku, Ni Hagi, San Karatsu. Raku first, Hagi second, Karatsu third.¹ The saying has circulated among tea ceremony practitioners for centuries, and its meaning is precise: if you are a devoted student of the way of tea, a raku chawan is the bowl you desire above all others. Not merely because it is old, or expensive, or historically significant, though it is all of these things. But because it embodies wabi, the aesthetic of simplicity, imperfection, and quiet beauty that Sen no Rikyu placed at the center of chanoyu, more completely than any other object in the tea room.

My black raku bowl is one of my favorites. I reach for it often, not only on formal occasions. At Tealife, we carry raku ware, and they are the most expensive bowls we stock. That cost is not incidental. It reflects what goes into making one, and what it means to hold one.

Raku ware (楽焼, raku-yaki) is a type of Japanese pottery originating in sixteenth-century Kyoto, made primarily in the form of chawan (tea bowls) for use in the Japanese tea ceremony. It is hand-formed without a potter's wheel using a technique called tezukune (手づくね), fired at low temperatures, and removed from the kiln while still glowing hot to cool in open air. The result is a porous bowl with a matte or subtly glossy glaze in black or red, deeply irregular in form, and designed to be held in two hands.

There are two classic types. Kuroraku (黒楽), the black bowl, is the original form associated with the founding potter Chojiro. Akaraku (赤楽), the red bowl, gets its color not from a red glaze but from the clay itself, which takes on a reddish-orange hue during firing.² Both types have been made by the Raku family continuously since the sixteenth century, and both are also produced by independent kilns working in the same tradition.

Raku ware is intended for use with matcha only, not acidic foods or liquids. A bowl should be soaked briefly in warm water before each use. It requires specific care, but it is an extraordinary choice for the daily matcha drinker who wants the most thoughtfully constructed bowl Japanese ceramics has produced.

If that is what you needed, you are done. If you want to understand where raku ware came from, what makes it physically remarkable, and how to find one that is right for you, read on.

The most important thing to understand about a raku chawan is that it was not designed to be admired. It was designed to be held.

Traditional raku ware is formed entirely by hand. There is no potter's wheel. The clay is shaped using tezukune, a technique in which the potter presses and builds the form using only the palms, compressing from a dense flat disc upward and inward until the walls rise to the desired height. The process leaves impressions. The bowl is never perfectly round. The rim describes a freehand arc. The foot, called the koudai (高台), is trimmed with a metal or bamboo scraper after the bowl has dried enough to hold its shape. Each tool mark remains visible in the finished piece.

This is intentional. The physical irregularity of a raku bowl is not a byproduct of the process. It is the point of the process. The bowl is meant to carry the trace of the hand that made it, and to respond differently to every hand that holds it afterward. Where a Tokoname kyusu is a masterwork of systematic refinement, a raku chawan is a record of a single encounter between a potter and a piece of clay.

Raku is fired at low temperatures, approximately 900°C to 1,000°C for akaraku and around 1,200°C for kuroraku, producing a clay body that never fully vitrifies.³ The result is a genuinely porous material. Practitioners have long understood this porosity as a warmth advantage: the bowl heats gradually in the hands and holds the tea at temperature through the full length of a ceremony, where the bowl may pass from guest to guest.⁴ Rikyu designed a practice around a bowl that would stay warm. The physical property and the philosophical intent are not separate.

A raku bowl begins as a lump of clay worked entirely in the hand. Once the tezukune forming is complete and the bowl has been trimmed, it is coated with glaze applied by brush. For kuroraku, this is a black glaze made from crushed stones from Kyoto's Kamo River, which allows it to melt at the low firing temperatures used.⁵ For akaraku, the bowl is fired without a colored glaze, and the clay's own iron content produces the characteristic reddish hue during oxidation firing.²

The bowl is then placed inside a small enclosed vessel called a saggar, which protects it during firing. For kuroraku, the bowl is fired individually. The kiln used is compact enough to have been operated indoors in Kyoto, a fact that contributed to raku ware's spread through the city's tea community during the Edo period. Firing is rapid by ceramic standards. When the glaze has melted and the bowl glows orange-red with heat, it is removed from the kiln with metal tongs and set directly in open air to cool. The speed of removal and the thermal shock of cooling in open air are part of the process, not the end of it. They shape the final surface, pulling glazes into their matte or glossy finish and causing the characteristic fine crazing in the glaze as it contracts.

The Raku family fires only a small number of bowls each year, in two sessions, in April and November. The scarcity is not managed for commercial effect. It reflects what is actually possible when each bowl is treated as a singular event.

One visible consequence of the removal process is worth knowing before you see your bowl for the first time. Because the bowl is gripped with metal tongs while still glowing, the tongs leave faint impressions on the outer surface of the clay. On a kuroraku bowl, these marks appear as slight compressions in the glaze, sometimes with a subtle variation in surface texture at the contact points. They are not damage. They are a direct trace of the moment the bowl left the kiln, a record of the exact point at which the potter's hand, extended through the tongs, made its last contact with the piece.⁶ Tong marks are visible on kuroraku bowls by Donyu dating to around 1650. In the context of a tradition that values every mark of the hand, this is entirely consistent.

The raku chawan is not a generic vessel that happens to be used for matcha. Its shape encodes a precise understanding of what making matcha requires, worked out over four and a half centuries of daily use in the tea room. For the everyday matcha drinker, these functional details are worth knowing before the first pour.

The interior of a raku chawan has a broad base that rises into the walls. At the very center of this base is a shallow, rounded depression called the chadamari (茶溜まり), which translates loosely as "tea pool." When you whisk matcha, the chadamari gathers the powder and water at the center of the bowl's floor, concentrating the liquid where the chasen tip is working. After drinking, it holds the last small amount of tea, which is traditionally observed as part of the ceremony. For the home user, it simply means the whisk has something to work against, which makes achieving a smooth, frothy matcha easier.⁷

Surrounding the chadamari is a slightly raised ring called the chasenzuri (茶筅摺り), the zone where the tip of the chasen traces its arc during whisking. In a well-proportioned raku bowl, this ring is wide enough that the chasen moves freely without the tines catching on the walls, and the bowl is deep enough that the motion generates foam without splashing.⁷ The straight-sided, slightly inward-tapering form of the classic raku chawan, a shape called hantsutsu-gata (半筒形, half-cylindrical), assists with this directly: the vertical walls contain the movement of the whisk, and the inward angle at the rim keeps the tea from climbing out during vigorous whisking.

The rim itself, the kuchizukuri (口づくり), is rarely even. On a traditional kuroraku bowl, the rim describes five subtle undulations called gogaku (五岳), a term used exclusively for raku ware. Go means five, gaku means mountain. The five peaks are not decorative. When the chasen and the chashaku (bamboo tea scoop) are rested on the bowl's rim between movements during a tea ceremony, the gogaku provides natural resting points that keep the utensils from sliding.⁷ When you bring the bowl to your lips, the slight inward curve of the rim guides the tea to your mouth without dripping.

These are not refinements added to an already functional bowl. They are the functional bowl. The raku chawan emerged from a collaboration between a potter and a tea master, iterated by sixteen generations of the same family over four centuries. What reads as quiet simplicity is the product of very deliberate attention to what happens when you make and drink a bowl of matcha.

Kuroraku (黒楽) is the original form. Chojiro's early bowls were black, low-walled, and almost entirely without decoration or surface movement. The glaze is matte to subtly glossy, applied thickly enough that the surface is not uniform. Each bowl is a variation on a theme that has held for four and a half centuries. Kuroraku bowls are traditionally associated with koicha (thick tea), the more concentrated and ceremonially significant preparation.

Akaraku (赤楽) is the red bowl. It is not red because of a red glaze. The reddish-orange color comes from the clay itself during firing, rather than from any applied colored glaze.² Because the color is in the clay rather than on it, akaraku bowls have a directness that black bowls do not. The material and the surface are the same thing. Akaraku bowls are often associated with usucha (thin tea), the lighter and more commonly prepared form.

Beyond these two classic types, individual potters within and outside the Raku family have developed their own glazing approaches. The third-generation head Donyu introduced glossy black glazes and colorful surface variations in the early Edo period. The independent potter Hon'ami Koetsu, working around the same time, developed his own style of raku bowl using slip decoration and a more dynamic surface. The tradition is not a single fixed form. It is a set of shared values expressed in individual objects.

Chojiro (長次郎, died 1592) is the founder of raku ware. His father Ameya came to Japan from China and worked in the sancai (three-color glaze) tradition of the Ming dynasty.⁸ Chojiro grew up in Kyoto working with these techniques and eventually became a tile maker, producing ridge tiles for Toyotomi Hideyoshi's Jurakudai palace. It was through this work that he came into contact with Sen no Rikyu.

Rikyu asked Chojiro to make tea bowls that could hold the spirit of wabi: simplicity, humility, the beauty of what is incomplete and impermanent. Chojiro's response was a bowl almost entirely without decoration, almost without movement, almost without color. The early bowls, initially called ima-yaki (contemporary ware) or Juraku-yaki after the red clay from the Jurakudai site, were unlike anything being made in Japanese ceramics at the time.⁹ Rikyu's influence is inextricable from Chojiro's achievement. The two men arrived at the raku chawan together.

Jokei (常慶, the second generation) is the generation through which the Raku name became official. After Chojiro's death, Toyotomi Hideyoshi presented Jokei with a golden seal bearing the character 楽 (raku), meaning enjoyment, ease, or contentment.¹⁰ The family adopted the character as their name from that point forward. Raku ware (楽焼) takes its name from this seal, not from any quality of the clay or process. It was, in the most literal sense, named by the most powerful man in Japan.

Donyu (道入, 1599 to 1656), known by the nickname Nonko, is the third generation and the figure who established that raku ware could be more than Chojiro's founding austerity.¹¹ He was Jokei's first son, born into the family workshop and trained there before coming under the influence of Hon'ami Koetsu. Where Chojiro's bowls are quiet and spiritually restrained, Donyu's are larger, more expressive, sometimes glossy, occasionally playful. The tension between Chojiro's founding restraint and Donyu's freedom is still visible in the range of raku ware produced today. Both impulses are authentic to the tradition.

Raku ware holds two notable firsts in Japanese ceramic history: it was the first ware to use a potter's seal mark, and the first to be developed through a direct and named collaboration between a potter and a patron.¹² These are not trivial distinctions. The second one, in particular, reframed what a tea bowl could be: not an object produced for a market, but a conversation between two people about what tea should feel like.

The Raku family has produced sixteen generations of potters working without interruption from Chojiro to the present head, Raku Kichizaemon XVI. Their bowls are rare, expensive, and closely held within the tea ceremony world. They are not the only source of raku ware.

From the Edo period onward, independent kilns in Kyoto and across Japan worked in the raku tradition.¹³ Some kilns were established by potters who had apprenticed at the Raku family studio, known as wakigama (branch kilns). Others developed independently, drawing on the shared principles of tezukune forming, low firing, and wabi aesthetics.

One of the most respected contemporary kilns working in the raku tradition is Shoraku Kiln (昭楽窯), located in Kameoka, Kyoto. The kiln has served as an official supplier to Daitokuji Temple, one of the most important Rinzai Zen temples in Kyoto and a historical center of chanoyu.¹⁴ Led by 佐々木虚室 (Sasaki Kyoshitsu), the kiln produces bowls that draw closely on the early raku aesthetic of Chojiro and the work of Hon'ami Koetsu. Their bowls are accessible to everyday buyers in a way that pieces by the Raku family head are not.

When buying a raku bowl outside the Raku family, look for a potter's seal on the foot of the bowl, a tomobako (original wooden storage box) where one is available, and clear information from the seller on the kiln and the potter's lineage or training. A raku bowl without provenance is not necessarily inferior, but provenance matters for both historical and practical reasons, including the ability to confirm what glazing materials were used.

Raku ware is designed for matcha. Use it for matcha.

Before each session, soak the bowl in warm water for thirty seconds to a minute. The porous clay body absorbs water into its surface, which does two things: it prevents the bowl from drawing heat away from your matcha too quickly, and it helps the bowl's pores release any residual trace of previous use. In winter especially, this step matters. A cold, unsoaked bowl can drop the temperature of your matcha noticeably before you have finished whisking.

Hold the bowl in two hands. This is not ceremony for its own sake. Raku bowls are shaped to be held this way, and the warmth of the clay against both palms is part of what using one feels like. The bowl is not particularly heavy, but it has a solidity and a texture that a porcelain bowl does not. Run your thumb along the koudai, the foot ring, after a session. The unglazed clay there is where the bowl's porosity is most direct.

Drink while the tea is warm. Do not leave matcha sitting in a raku bowl. Rinse the bowl promptly after use. Wipe the inside clean of any matcha residue with a soft cloth or your fingertips under running water. Do not use detergent, which can penetrate the porous body and alter the bowl's character.

On the glaze and safety. Traditional raku glazes contain small amounts of lead, which allows the glaze to melt at the low temperatures used in raku firing. Japan's Ministry of Health, Labor and Welfare has specifically addressed raku ware in its tableware safety guidelines, and the recommendation is to use raku bowls for matcha only, not for acidic foods or liquids such as vinegar-dressed dishes, fruit juices, or wine.¹⁵ Matcha is alkaline rather than acidic, and the contact time during normal tea preparation is short. Under these conditions, leaching is not a concern. The bowl is safe for its intended purpose. Do not use it for anything else.

Many contemporary raku potters, including independent kiln makers, now use lead-free frit in their glazes. If lead content is a concern for you, ask your supplier directly. A responsible seller will know what their potter uses.

The key rule is simple: raku ware must dry completely between uses.

After rinsing, pat the bowl dry with a clean cloth and place it upright on an absorbent surface, mouth upward, to air dry fully before storage. Because the clay body is porous, water penetrates both the glaze surface and the clay underneath. This takes longer to release than you might expect, particularly in humid climates. In Singapore, where humidity is high, allow at least several hours. If you store the bowl while still damp, you risk mold developing inside the clay body, which is difficult to remove and can permanently alter the bowl's smell.

Never put a raku bowl in a dishwasher. Never use soap or any cleaning agent on the interior. Never soak the bowl for extended periods, which can cause the clay to absorb water in a way that stresses the body over time.

When storing, wrap the bowl in a soft cloth, ideally the piece of cloth traditionally stored with it in the tomobako. The wooden box itself is not decorative storage: it regulates humidity and protects the bowl from impacts that porous, low-fired clay is less equipped to absorb than high-fired stoneware.

Over time, the bowl will change. The pores accumulate trace character from repeated use. The glaze may develop additional crazing lines, particularly if the bowl experiences temperature change. This is not damage. In raku ware, aging is part of the object's biography.

If you search for raku pottery online, you will encounter two very different things. One is Japanese raku ware as described in this article. The other is what is known as Western raku firing, a studio ceramics technique developed in the United States in the 1960s by ceramicist Paul Soldner, inspired by Bernard Leach's writings about Japanese practice.

Western raku typically involves pulling pots from the kiln while hot and placing them into containers filled with combustible material such as sawdust or newspaper, which creates a reduction atmosphere and produces dramatic metallic and smoky surface effects. The results are visually striking, often brightly colored, and entirely unlike anything produced in the Japanese raku tradition. The two techniques share a name and almost nothing else. The clay bodies, the glazes, the philosophy, and the aesthetic outcomes are completely different. Pieces of Western raku are generally not recommended for drinking use at all.

The debate over the name has not been quiet. At a ceramics conference in Kyoto in 1979, the then-head of the Raku family and Paul Soldner argued directly about whether Western potters had the right to use the word raku for their work.¹⁶ The Raku family's position was that work by other makers should take its own name. That position has not changed. Japanese raku ware and Western raku firing remain, despite sharing a word, distinct traditions.

A raku chawan is not for everyone, and it would be dishonest to suggest otherwise.

If you drink matcha quickly, rinse the bowl and put it away without thinking about it, a raku bowl is not the right bowl for you. The care it requires is not complicated, but it is specific, and it will feel like a burden if you are not interested in what the bowl offers in return.

If you practice tea ceremony, or are beginning to, a raku bowl is worth saving for. It is the bowl most closely associated with the tradition you are learning, and using one sharpens what you are trying to understand about wabi. Your teacher will guide you on when and how to introduce it into your practice.

If you make matcha daily and care about the object you use, a raku chawan from an independent Kyoto kiln is one of the most considered purchases in Japanese ceramics available to an everyday buyer. It is not fragile in the way that anxious handling would imply. It is porous and low-fired, which means it needs specific care, but it is not delicate. People have drunk from raku bowls daily for four hundred years. The object is tested.

What raku ware gives you that no other bowl does is presence. A Tokoname kyusu is precise and reliable. A porcelain chawan is clean and light. A raku chawan is a thing that was made by a specific person, by hand, and left to become what the kiln made of it. When you hold it in two hands and feel the clay warm under your palms, you are doing exactly what every person who has ever used that type of bowl has done. The continuity is not metaphorical. It is physical.
