In a nutshell

Mashiko ware (益子焼) is a Japanese stoneware pottery from the town of Mashiko in Tochigi Prefecture, about a hundred kilometers north of Tokyo. It traces back to the potter Ōtsuka Keizaburō, who began production there in 1853, initially supplying everyday tableware for the market in Edo. The local clay is sandy, containing silica and iron, and yields thick-walled, heavy vessels. Characteristic are bold glazes made from regional raw materials: the reddish-brown kaki glaze from iron-rich Ashinuma stone, the milky nuka from rice husk ash, and the toffee-brown ame. From 1924 onward, the potter Hamada Shōji made Mashiko the center of the Mingei movement.

About a hundred kilometers north of Tokyo lies a place whose name carries particular weight among ceramics lovers worldwide – even though for decades nothing was produced there but everyday kitchenware: water jars, storage pots, plates, grating bowls. The clay was coarse, the glazes dark and thickly applied, the forms heavy. It was only in the 20th century that this unspectacular production became something else. Mashiko became the place where Japanese utilitarian ceramics turned into a deliberate aesthetic program – and from where the conviction that a simply thrown bowl can hold more beauty than any showpiece traveled by way of England to the rest of Europe.

What Is Mashiko-yaki?

Mashiko-yaki (益子焼) is a Japanese stoneware pottery from the small town of Mashiko in Tochigi Prefecture, in northern Kantō. Its history begins in 1853, when the potter Ōtsuka Keizaburō found a clay there that was well suited to vessels. This clay is rich in silica and iron, distinctly sandy and coarse-grained; it can barely be drawn thin, which is why Mashiko ware traditionally turns out thick-walled and heavy. Characteristic are strong glazes obtained from local raw materials – foremost among them the reddish-brown kaki glaze (persimmon glaze), the milky-white nuka (rice husk ash glaze), and the glossy toffee-brown ame (candy glaze). Since 1979, Mashiko-yaki has been registered as Dentōteki Kōgeihin, a state-recognized traditional craft. To this day, what is produced above all are things handled daily: bowls, plates, cups, vases, and sake vessels.

A Potter from Kasama Finds the Right Clay

Ōtsuka Keizaburō, who is regarded as the founder of Mashiko-yaki, had learned his craft in nearby Kasama, in what was then Hitachi Province, today's Ibaraki. In 1853 he took up production in Mashiko. The local feudal lord promoted the young trade: Ōtsuka was appointed official potter, and anyone newly trying their hand at ceramic production could count on financial support. Further potters came from Kasama to join him. What they produced was expressly not arts and crafts but everyday mass goods: water jars, storage vessels, grinding bowls, plates, and bowls that were delivered to Edo, later Tokyo. By the end of the Meiji period, more than fifty households in Mashiko were already making their living from pottery. The close kinship with Kasama is still perceptible today; the two places are often mentioned in the same breath. The Japanese register of traditional crafts explicitly names Kasama-yaki as the point of origin: Mashiko-yaki, it states, began in the mid-19th century under its influence, promoted by the domain, and its ware was in use in the kitchens of Edo.

The clay of Ōtsuzawa and what it allows

The raw material shapes this ceramics more strongly than in most other Japanese traditions, since in Mashiko the clay is usually processed without additives. It comes primarily from the Ōtsuzawa district and the surrounding hills, is rich in silica and iron compounds, and contains so much fine sand that it feels rough and not very pliable. For it to be thrown at all, it must be prepared and wedged for a long time. It does not allow for filigree, thin-walled forms in the manner of porcelain traditions – but in return it is remarkably fire-resistant and yields vessels with a noticeable weight, that sit solidly in the hand and whose foot retains a grainy, almost sandy surface. It is precisely this quiet heaviness and the slightly irregular skin that many collectors in German-speaking countries mean when they search for Wabi Sabi pottery.

Kaki, Nuka, and Ame – Glazes from the Region

Just as local as the clay are the glazes. The best known is Kaki, the "persimmon glaze": it is obtained from Ashinuma stone, an iron-rich tuff from the region, and fires to a rich reddish-brown reminiscent of the color of ripe persimmons. Opposite it stands Nuka, a milky-white, almost opalescent ash glaze whose base is formed by the ash of rice husks and rice straw from the harvest. Ame, the "candy glaze," owes its name to the transparent, glossy toffee-brown that results from the addition of manganese. In addition, there are a greenish celadon and a cobalt-blue glaze. Altogether, in Mashiko one traditionally works with a manageable number of base glazes, whose color intensity derives from iron, copper, manganese, cobalt, and chromium; they are applied by pouring, dipping, or with broad brushes, not infrequently made of dog hair.

Hamada Shōji Moves to Mashiko in 1924

The turning point came with a newcomer. Hamada Shōji (1894–1978), a trained ceramicist from what is now Kanagawa, had gone to England together with the British potter Bernard Leach in 1920 and had built a workshop with an East Asian chamber kiln in St Ives, Cornwall. In 1923 he returned to Japan, and in 1924 he settled in Mashiko – not in one of the famous tea ceramics centers, but in a place that produced heavy everyday tableware. This was precisely the point of the decision. Hamada worked consistently with the local clay, the local glazes, and with tools made of bamboo and dog hair, rather than having material delivered to him. Out of this self-imposed restraint came a body of work of great calm: wide bowls, squat vases, plates with a few, swiftly applied brushstrokes. In 1955, in the very first class of this honor, he was named Ningen Kokuhō, a "Living National Treasure." Mashiko remained his base until his death. The Japanese register of traditional crafts dates Hamada's formative influence to the beginning of his artistic career in 1924, and to this day lists white engobe (hakeme and slip) among the traditional techniques of the place.

Mingei: The Beauty of Use

Hamada was not alone in this. Together with the philosopher Yanagi Sōetsu (1889–1961) and the potter Kawai Kanjirō, he coined the term Mingei (folk craft) in 1925, a shortened form of minshūteki kōgei. Behind it was a thesis that was provocative for its time: the most beautiful things were not the showpieces made by famous artists for wealthy patrons, but the anonymously produced everyday objects of simple craftsmen. Yanagi captured this in the term yō no bi, the "beauty of use." The movement explicitly understood itself as a response to Japan's rapid industrialization and Westernization. In 1936, the Nihon Mingeikan, the Japan Folk Crafts Museum, opened in Tokyo, with Yanagi as its first director. For Mashiko, this meant a complete reevaluation: what had previously been considered cheap ware was suddenly regarded as the standard.

Via St Ives to Europe

The second half of this story takes place in England. Bernard Leach (1887–1979), who had become a potter in Japan, remained a close friend of Hamada throughout his life; the two died in 1978 and 1979, just months apart. In 1934, Leach traveled to Japan again for about fifteen months and became closely acquainted with the local country potteries there. His book "A Potter's Book," published in 1940, combined technical instruction with a veritable philosophy of life and became a standard work for generations of European potters. Through this book – and through the workshop in St Ives, through which countless apprentices passed – the ideas of Mashiko and Mingei found their way into European studio ceramics. The fact that ash glazes are mixed and deliberately irregular bowls are prized in workshops between Cornwall and Central Europe has much to do with this connection.

After Hamada: Shimaoka Tatsuzō and the Legacy

Hamada's best-known student was Shimaoka Tatsuzō (1919–2007). After completing his apprenticeship, he opened his own workshop in the immediate neighborhood in 1953, where he developed the technique of Jōmon-Zōgan (cord-impressed inlay): he rolled braided cords into the soft clay, filled the impressions with white slip, and thus created a fine, textile-like pattern reminiscent of the ceramics of the prehistoric Jōmon period. In 1996 he too was designated a Living National Treasure – the second potter from Mashiko after his teacher. Hamada's residence and his collection have been publicly accessible since 1977 as the Mashiko Sankokan. In it, he had gathered ceramics, lacquer, wood, metal, and textiles from many countries, which served him as reference material for his own work.

What Kinds of Vessels Are Made in Mashiko

To this day, the repertoire is conceived from use. Alongside yunomi (handleless tea cups), chawan (tea bowls), plates, and bowls, vases, sake vessels, and large storage vessels are also made. Shaping is done predominantly on the potter's wheel, while slabs are also built up and molds are used. A bisque firing at about 700 to 800 degrees is followed by the glaze firing at around 1,200 to 1,300 degrees. Before glazing, many workshops apply white slip or quick brushstrokes – a decoration that is set in seconds and, precisely for that reason, never turns out the same twice. Toward the tea ceremony in the narrower sense, Mashiko-yaki has a more relaxed relationship than, for instance, Raku ware or Hagi ware; its strength lies in everyday tea, in rice, in sake. Where clay, glaze, and fire are tamed so little, handcrafted Japanese ceramics emerge as unique works: no firing repeats the previous one exactly, and even the position of a vessel in the kiln determines how deep the reddish brown of the iron glaze turns out.

March 11, 2011, and the Rebuilding of the Kilns

The Tōhoku earthquake of March 11, 2011, struck Tochigi Prefecture with full force as well. In Mashiko, nearly all noborigama, the chambered climbing kilns built into hillsides, collapsed; shelves toppled, and entire years' worth of production shattered. The damage to the town's pottery trade was estimated at about 770 million yen, roughly one-fifth of annual sales, of which around 550 million yen alone went toward repairing the kilns. What happened afterward has by now become as much a part of this place's history as its glazes: potters from Japan and abroad came to help rebuild the kilns. Some noborigama were rebuilt from the ground up.

Today the number of active workshops in Mashiko is usually put at around 250. Twice a year, during Golden Week in late April and early May and around November 3, the Mashiko Tōki Ichi pottery market turns the town into a single marketplace: several hundred tents join the roughly fifty permanent shops, and visitor numbers are cited in the range of half a million. The market's history can be traced back to 1966.

An Attitude You Can Hold in Your Hand

Anyone who picks up a simply thrown, boldly glazed bowl understands faster than any text what the Mingei movement was about: things that want to be used and become more beautiful in the process. This attitude has never been lost in the workshops of Japan – as little in the country's older kiln landscapes as in Mashiko. At densho.de you will find handcrafted Japanese ceramic unique works in which precisely this connection between everyday usability and quiet form becomes apparent: tea bowls, sake vessels, and vases, each piece individually sourced from Japan and shaped by a potter's hand. Anyone who wants to buy Japanese ceramics that don't look like series production but like a workshop will find pieces in our selection in which clay, glaze, and fire can still be read.
