If someone were to ask you, “What is the most Japanese piece of all?”, the Raku tea bowl (matcha bowl, chawan) would surely be among the answers. That is because Raku ware is equivalent, in the form of a single piece, to the history and philosophy of Japanese ceramics. The spirit of “wabi-cha” embodied by Sen no Rikyū — “within imperfection lies perfect beauty” — is expressed in its purest form by the Raku tea bowl.

Born in 16th-century Kyoto and still handed down today, more than 450 years later, by the family known as the Raku family (Rakke): that is Raku ware. It is not merely “the production of tea utensils,” but a living cultural heritage that continues to pass Japan’s aesthetics and philosophy on to the next generation.

The Birth of Raku Ware: The Meeting with Sen no Rikyū

The Perfection of Wabi-cha and an Age of Revolution in the Tea Bowl

Japan in the latter half of the 16th century was a turbulent age in which the end of the Warring States period overlapped with the beginning of the early modern era. In the ages before, the way of tea (the tea ceremony) had also been a stage for warlords to display their power, and lavish tea bowls imported from China (karamono) were prized.

The one who directly challenged this current was the tea master Sen no Rikyū (1522–1591). As Rikyū perfected the spirit of “wabi-cha” — a tea that finds beauty within simplicity and stillness — he raised a fundamental question about the piece itself: “The tea bowl need not be a lavish Chinese one. A piece born from Japanese clay and Japanese sensibility, possessing the beauty of wabi — that is the true tea bowl.”

The one who gave this idea the form of a piece was a Kyoto roof-tile craftsman, Chōjirō. The “wabi tea bowl” born from the collaboration between Rikyū and Chōjirō is the origin of Raku ware.

The tea bowls Chōjirō made overturned the common sense of the ceramics of the time. Without using the potter’s wheel, he kneaded the clay by hand and shaped it with his fingers — a technique called “hand-building (tebineri)” — and the glaze was black or red only. The form was asymmetrical, slightly distorted. This is the beginning of Raku ware.

Yet this very “imperfection” matched the spirit of wabi-cha perfectly. The sight of white matcha foaming in a black tea bowl, in the light streaming through the small window of a tea room. Precisely because it is not perfect, it was a beauty that touched the heart deeply.

The Birth of the Raku Family

Chōjirō’s successor, Tanaka Sōkei, was granted the character “Raku” by Toyotomi Hideyoshi — the famous samurai who unified Japan — and thereafter established a house of potters that has continued for generations as the “Raku family (Rakke).” The current head is the sixteenth-generation Raku Kichizaemon, and the Raku family has guarded the tradition of Raku ware for more than 450 years.

The Techniques of Raku Ware: Hand-building and the Philosophy of Drawing from the Kiln

The Wheel-less Hand-building (Tebineri) Technique

The greatest feature of Raku ware is its “hand-building (tebineri)” forming, which does not use the potter’s wheel.

The maker kneads the clay with both hands and presses it outward with the fingers to create the form. In this process, the traces of the maker’s fingers remain directly in the clay. It is the embodiment of Rikyū’s philosophy that “a piece should hold the warmth of the hand of the one who uses it.”

A piece made on the wheel aims for a perfect circle. But the hand-built (tebineri) Raku ware deliberately takes the position that “it need not be a perfect circle.” The subtle distortion and asymmetry that result create a “softness” that fits perfectly into the hand of the one who holds the tea bowl.

Glazing and Firing

The glazes of Raku ware are mainly of two kinds, black and red.

Kuro-Raku (Black Raku)

A black glaze containing manganese oxide and iron. The black, fired strongly within the kiln, has a depth of texture in which one seems to “see a universe within the black.” It was the color Sen no Rikyū loved most.

Aka-Raku (Red Raku)

A red glaze containing iron oxide. Warmer than Kuro-Raku, the red that shines in the light evokes a sense of vitality. It is said that “Aka-Raku shines in bright places, Kuro-Raku in dark places.”

Firing is done in a small raku kiln (raku-gama) at a relatively low temperature (800–1,100°C). The firing time, too, is shorter than for other pottery, preserving Raku ware’s own style of “firing one piece intensively.”

The Miracle of “Kiln Effects (Yōhen)” at the Moment of Drawing from the Kiln

One of the most dramatic moments in Raku ware is the moment of drawing the work from the kiln.

The moment when a piece, taken from the high-temperature kiln by bare hand (with special tongs), is cooled in the open air. In this process, the glaze undergoes unpredictable change. This is called “kiln effects (yōhen).”

The silver luster that appears on the surface of Kuro-Raku, the subtle unevenness of color in Aka-Raku — these are “gifts of flame and time” that the maker cannot control. Even within Japanese ceramic art, there are few wares like Raku that “place chance at the very center of their philosophy.”

Raku Ware and the Tea Ceremony

In the tea ceremony, the tea bowl is not merely a piece but the center of a total experience of “seeing, touching, and using.” The way of appreciating the tea bowl is itself defined as an etiquette in the tea ceremony, called the “midokoro (points to appreciate).” There are broadly three midokoro in a tea bowl.

The front (shōmen): A tea bowl always has a “front.” The face that most beautifully shows each piece’s distinctive expression — its “keshiki” (the flow of glaze and kiln effects) — is set as the front and turned toward the guest.
The foot ring (kōdai): The making of the base shows the maker’s technique and philosophy. The foot ring of Raku ware is a part that should be examined with special care.
The rim (kuchitsukuri): The shape and thickness of the drinking rim. A rim that is neither too thin nor too thick, and settles naturally against the lip, is considered ideal.

Why Raku Ware Is Placed Highest in the Tea Ceremony

In the tea ceremony, the Raku tea bowl holds a special position. As mentioned earlier, it is Raku ware that is named first in the maxim “first Raku, second Hagi, third Karatsu (ichi-Raku, ni-Hagi, san-Karatsu),” a ranking of tea bowls.

The reason is that Raku ware is “the piece that most purely embodies the spirit of wabi-cha.” Not lavishness, but depth of spirituality. This is the value the tea ceremony holds most dear, and Raku ware embodies it.

What Raku Ware Conveys to the World

In the present day, Raku ware has branched into an entirely different style called “American Raku.”

American Raku is a firing method that developed and became established in the West from Japan’s traditional Raku ware. Japanese Raku ware is said to have been introduced abroad by the English potter Bernard Leach and others. To the Western makers of the time, the Kuro-Raku technique of rapidly cooling a tea bowl heated to over 1,000°C in water, and the method of altering the glaze by smoking it with leaves or sawdust, appeared very fresh. Its improvisational quality, in particular, seems to have made it all the more appealing to rationalist Western makers.

Later, in the 1960s, it was brought to America by the American potter Paul Soldner, and branched into an entirely different style called “American Raku.”

The Features of American Raku

American Raku, while referring to the techniques of Raku ware, has achieved its own development. Japanese Raku ware is basically black and red, but American Raku is extremely colorful.

Using glazes that contain metallic components such as copper, and applying reduction (smoking), metallic lusters like rainbow colors, gold, and copper appear.

The contrast between turquoise-blue or white glazes and a body blackened by smoke is very intense, with the air of contemporary art. Free creation, unbound by the format of the “tea bowl,” is also a feature.

What is most taken up, even within Raku ware, is chance. Because the expression changes every time depending on the wind direction when it is drawn from the kiln, the amount of sawdust, and the timing of insertion, enjoying works as “art born of chance” faithfully follows the very way of enjoying, and the aesthetics of, Raku ware itself.

Its making philosophy and technique differ greatly from Japanese Raku ware, but they share the spirit of “seeking the beauty of a piece between chance and intention.” The fact that the thought of Raku ware crossed the Pacific to give birth to new creation shows the universal power that Raku ware possesses.

Frequently Asked Questions About Raku Ware

Q1. What kind of pottery is Raku ware (raku-yaki)?

Raku ware is a pottery made exclusively for the tea ceremony, founded in the latter half of the 16th century (the Azuchi-Momoyama period) by the first-generation Chōjirō, under the concept of Sen no Rikyū. It is characterized by the “hand-building (tebineri)” technique of shaping with only the hands and a spatula, without using the wheel, so that the maker’s finger traces and distortions become the very flavor of the piece. “Kuro-Raku” and “Aka-Raku” are representative, and it is a pottery that symbolizes the spirit of “wabi-cha” that Sen no Rikyū pursued.

Q2. What should I be careful about in handling and caring for Raku ware?

Because it is very delicate and highly absorbent, it requires careful handling.

・Before use: Lightly passing it through lukewarm water helps prevent tea stains and odors from soaking in. (※ Please avoid sealing (medome) that involves sudden treatment with boiling water or long boiling, as it may cause damage.)

・After use: Wash with a soft sponge and lukewarm water. Because it is highly absorbent, refrain from using detergent, and dry it thoroughly by air. If moisture remains, it can cause mold.

・What not to do: Absolutely avoid using a dishwasher, microwave, or scouring cleanser.

The Perfect Beauty Within the Imperfection of Raku Ware

When you take a Raku tea bowl in hand, you are touching 450 years of time. The spirit of Sen no Rikyū’s wabi-cha, the finger traces of Chōjirō, the reflection of generations of the Raku family — all of these are compressed within a single work.

It is a piece that is “not perfect.” It is distorted, asymmetrical, and the pattern of its kiln effects is unpredictable. But precisely for that reason, it settles into the shape of your hand, holds a “keshiki” that is yours alone, and makes your time of tea one of a kind.

From here, take the first step of touching the deep Japanese idea of “the beauty of imperfection.”
