Rustic Abstraction in Japanese Ceramics

Long before Rothko and Pollock sought to establish a new language of artistic expression, on the other side of the Pacific, Japanese ceramists have been quietly making another kind of abstract art “painted” not on canvas but on clay using fire and ash as their medium to express profound emotions too deep for words. Their works manifest in tea bowls, sake cups and sake flasks, incense burners for the tea ceremony, flower vases and eventually, non-functional sculptures.

A Transformative Art

In place of paint, these artisans relied on the kiln, on wood ash and fire, and sometimes on rice straw and rice husks, letting nature create unrepeatable patterns that often appear uncannily like Western abstract art. For want of a better term, I will call this style of ceramic art, “Rustic Abstraction.”

One Word: Wabi-sabi

More formally, rustic abstraction is an established aesthetic in Japanese ceramics that merges the wabi-sabi tradition with contemporary artistic sensibility, particularly its penchant for abstract expression.

In ceramics, wabi-sabi favors the raw, earthly and unadorned qualities of pottery. It also regards imperfections as a supreme form of “unpretentious beauty,” mirroring life itself.

Blending this form of rusticity with contemporary abstraction gives rise to a unique form of art, one that celebrates the quiet simplicity of the wabi-sabi tradition with the artistic freedom of abstract art.

Features of Rustic Abstract Ceramics

Works in the rustic abstract style share a few common features:

Asymmetric Forms

Rather than use the potter’s wheel to create flawless symmetry, ceramic artists use hand-building techniques such as coiling, slab-building and pinching to create asymmetric shapes that accord with the wabi-sabi notion of finding beauty in the imperfect.

Natural or Uneven Glazes

The archetype rustic object is fired without using artificial glaze. Instead, the potter relies on the natural effects of firing and wood ash to create a coarse appearance as though the object is unearthed from an archaeological dig. While such ceramics – known as yakishime – are deeply rustic, some rustic abstract works feature intentional glazing but applied unevenly and unpretentiously in the spirit of spontaneity.

Celebration of Flaws

A third source of rustic abstraction comes from embracing cracks, rough surfaces, and uneven or jagged edges as acts of rebellion against pristine beauty and industrial perfection.

Bizen Ceramics

All exhibits are from the Museum of Modern Ceramics SG unless indicated.

Traditional Bizen ceramics are fired without glazes, relying instead on high temperature and the erratic swirl of wood ash during firing to impart abstract patterns on the clay body. So highly valued are these patterns that special names are given to them: goma (sesame seed pattern), sangiri (smoked pattern), hiro (diffused scarlet flame marks), and hidasuki (red cord-like markings). These natural patterns give Bizen ware their distinctive charm. They also often resemble the expressions found in modern abstract art such as paintings by Mark Rothko and Helen Frankenthaler.

The timeless simplicity of wabi-sabi aesthetics still resonates in Japanese ceramics today.

ISEZAKI Jun's bold sculpture "Wind and Snow" is a prototype of the "classic contemporary" style many contemporary Bizen ceramicists strive to emulate.

ISEZAKI Koichiro (b. 1974), rectangular Bizen vase with hiro (flame mark) patterns, H 30 cm x W 9.6 cm.

A minimalist rectangular vase with superb flame mark patterns by Isezaki Koichiro, the eldest son of the late Living National Treasure, Isezaki Jun. He continues the family’s storied tradition of making Bizen ware that, while rooted in traditional techniques, embody a distinct contemporary vision.

WAKIMOTO Hiroyuki (b. 1952), sake flask (tokkuri) with abstract flame marks (hiro), natural ash glaze, H 13.2 cm x W 8 cm.

A sake bottle by the innovative Bizen potter Wakimoto Hiroyuki featuring dramatic fire marks (hiro) on a predominantly ash-grey speckled surface. Born in 1952 in Nagasaki. Wakimoto established his kiln in Bizen city in Okayama Prefecture after studying under master potter Joji Yamashita. He is celebrated for his modern take on centuries-old Bizen ware in works in his functional and sculptural works.

TAKENAKA Kenji (b. 1957), Chamfered cup, natural ash glaze, H 7.5 cm x W 9.5 cm.

A chamfered tea cup with a subtle two-tone surface that echoes the abstract paintings of Mark Rothko. Takenaka Kenji is an acclaimed Bizen ceramicist known for his expressive natural ash glazed Bizen ware and innovative use of applied glazes (see next example).

TAKENAKA Kenji (b. 1957), black Bizen sake cup with red glaze, H 10 cm x W 7 cm.

A charcoal-black sake cup by Takenaka Kenji combining the rugged character of Bizen ware with an abstract application of vivid red glaze that transforms it into a work of art. The cup’s visual appeal is enhanced by the faceted form that gives it a dignified sculptural presence.

Shino Ceramics

All exhibits are from the Museum of Modern Ceramics SG unless indicated.

Shino ware is known for their thick milky-white glaze made from ground felspar that when fired, creates features as subtle orange scorch marks (hi-ro), crawling glaze and tiny pinholes commonly known as “yuzu skin.” These features give Shino ceramics an appealing tactile quality in addition to the natural glaze patterns that look like abstract expressionist brushstrokes. Important Shino ceramicists include Living National Treasure, Suzuki Osamu (Kura), Hayashi Kotaro, Hayashi Shotaro, and Kato Takahiro, grandson of the legendary Mino potter, Kato Tokuro.

SUZUKI Osamu (b. 1934), Red Shino tea bowl, H 9 cm x W 13.3 cm. Private collection.

A vibrant tea bowl by Living National Treasure Suzuki Osamu featuring thick white Shino glaze over iron-rich reddish-orange clay. Suzuki famously revolutionized Shino ware by perfecting it inside a modern gas kiln, a feat previously thought achievable only via wood-burning kilns. His mastery over slow-firing and reduction led to pieces like this tea bowl where deep crimson clay breaks through the snow-white Shino glaze, yielding dramatic abstract patterns of color and texture.

HAYASHI Kotaro (1940-1981), tea bowl with iron oxide underglaze, H 8cm x W 12 cm.

A well-shaped tea bowl by the talented Shino potter Hayashi Kotaro featuring delicate iron-oxide painting evoking a scene of wind-blown leaves. The surface itself is a pitted landscape of white, orange, and red that emerged naturally from the wood firing in an anagama kiln. The fine quality of this tea bowl is characteristic of Hayashi’s work. Very few of his works survive due to his untimely death at the age of 41.

KATO Takahiro (b. 1972), Bevelled tea bowl, stoneware with iron painting and Shino glaze, H 12.5 cm x W 13.3 cm. Private collection.

A Shino tea bowl with iron oxide brushstrokes by Kato Takahiro who comes from one of Japan’s most celebrated ceramic families. Takahiro works with Mino wares such as Shino, Setoguro and Oribe, infusing them with a raw, earthly quality combined with modern, abstract expressions.

HAYASHI Shotaro (b. 1947), Square vase, natural glaze, H 23 cm x W 22 cm.

HAYASHI Shotaro (b. 1947), Square vase, natural ash, H 23 cm x W 22 cm.

A squarish vase with the rich textures and colors associated with Shino ware. The surface is coated in a milky white Shino glaze that pools and crawls across surface, revealing the warm red iron clay beneath.

Robert FORNELL, Black Shino tea caddy, reduction-fired, H 10 cm x W 6 cm.

Robert Fornell spent a decade learning pottery in Japan before starting his independent kiln in the US. His works are functional and sculptural at the same time, blending traditional wabi-sabi aesthetics with a distinct modern sensibility evident in this bevelled black Shino tea caddy.

Elena RENKER, Shino tea bowl with iron oxide painting, H 9 cm x W 11.5 cm.

A tea bowl by New Zealand-based Elena Renker who specializes in making Shino functional ware that blends the wabi-sabi tradition with contemporary aesthetics. The bowl is hand-carved using three types of clay mixed with grog, brushed with iron oxide glaze before being fired for days in a wood-fired kiln.

Shigaraki Ceramics

All exhibits are from the Museum of Modern Ceramics SG unless indicated.

The clay bed from Lake Biwa yields a coarse, sandy material packed with fragments of quartz and feldspar. Artists working in Shigaraki style throw or hand-build rugged form vessels which are fired for 3 to 7 days in a wood kiln. As the clay is fired, the embedded mineral chunks explode through the surface, creating an inherently abstract, craggy landscape that mimics mountain cliffs. Other notable natural glaze patterns include crab’s eye (kani-me) - small white protrusions of bursting feldspar that freckle the surface - and the well-loved bidoro effect - a glassy green glaze formed when melting pine-wood ash fuses with the quartz in the clay body. These features give Shigaraki vessels a rugged distressed look that resembles some modern avant-garde sculptures.

KATO Takahiko (b. 1952), Hanging vase, natural ash glaze, H 16.5 cm x W 9.4 cm. Private collection.

Shigaraki hanging vase by Kato Takakiko showcasing the expressive character of his work. On the roughly-textured body, natural ash glazes swirl around vivid green glaze deposits known as bidoro, creating a “canvas” of natural abstract patterns forged by intense wood-firing.

Unknown artist, torn vessel with flame marks, H 27 cm x W 28 cm. Private collection.

An attractive sculptural wood-fired vessel with a deliberately torn rim and a surface decorated with flame marks (hiro) from wood firing. There are also sprays of “stone bursts” (ishihaze) produced due to small pebbles and mineral impurites embedded in the clay migrating to the surface during firing.

KOHYAMA Yasuhisa (b. 1936), Faceted vase, hand-built, wood-fired, H 17.5 cm x W 13.5 cm.

A faceted vase by the celebrated ceramicist, Kohyama Yasuhisa who is known for his contemporary take on centuries-old Shigaraki ceramics. This vase displays subtle color tones ranging from biege to deep orange, achieved by careful positioning of the vessel in the wood-firing kiln to catch desired effects from the flame flux. On one side, vertical and horizontal grooves are incised to suggest an abstract face with nose and pursed lips.

Iga Ceramics

All exhibits are from the Museum of Modern Ceramics SG unless indicated.

Geologically linked to Shigaraki, Iga ceramics is also defined by their coarse surfaces, deliberate imperfections such as cracks and deep grooves and heavy scorching that lend these objects a distressed form that feels ancient yet radically modern. Indeed, the distressed look of Shigaraki and Iga ware has influenced many prominent Western artists like the famed American potter, Peter Volkous who formulated his own rugged clay in the US to create the “Iga look” for his contemporary sculptures.

ATARASHI Manabu (b. 1973), Vase, natural ash glazes, H 14.7 cm x W 9.3 cm.

A highly charismatic vase by one of the foremost contemporary practitioner of the Iga pottery style. The vase embodies the artist’s signature blend of traditional and modern aesthetics, utilising a rugged, rock-like form to complement the natural beauty of Iga ware, including fire color, scorch marks and the green glassy glaze deposits known as bidoro (often referred to as “dragon’s eye”).

KATO Tokuro (1898-1985), Iga-Mino style tea caddy, iron-oxide and Shino glaze, H 9.5 cm x W 5.8 cm.

A superb tea caddy by Kato Tokuro, one of the most celebrated and influential potter of the 20th century. Kato dedicated his life to reviving classical pottery styles of the 16th and 17th centuries, including Shino, Oribe and Iga wares. This tea caddy showcases his attention to details of form and his mastery of Shino and iron-oxide glazes, which is applied on this tea caddy with great aplomb. It is a masterpiece of functional art that transcends tradition into the realm of modern abstraction.

FUJIOKA Shuhei (b. 1947), Irregular form vase, wood-fired, natural ash glaze, H 25 cm x W 12.5 cm.

Tall vase with a highly textured surface that emphasizes the elemental beauty of Iga ware. The body is carved with pronounced vertical ridges and faceted planes, giving the vase a hewn mountain-like appearance. Its sculptural presence is complemented by a rich palette of muted color tones from creamy grey to scorched brown and black, which emerged naturally from the wood-firing. Born in 1947 in Ehime Prefecture, Fujioka Shuhei is one of the most distinguished potter of post-war Japan, renowned for works that successfully blend tradition with bold, modern forms.

ATARASHI Manabu (b. 1973), lidded vessel in the shape of a dancer, natural ash glaze, H 21 cm x W 16 cm.

An ingeniously constructed lidded vessel that can be used as a pourer . Expertly carved from a single block of clay, the sweeping arcs become the arms of a dancer in the motion of a traditional Odori or Mai dance. The piece was fired unglazed in a pine wood-burning kiln over several days, resulting in a richly-textured surface with subtle variations in colors and sporadic spots of ishihaze (stone bursts) from the intense heat. A leading figure of contemporary Iga ware, Atarashi Manabu is celebrated for bridging the gap between the raw, rustic look of Iga ware with a contemporary artistic vision.

Iga Ceramics

All exhibits are from the Museum of Modern Ceramics SG unless indicated.

Hagi ware (Hagi-yaki) is a renowned 400-year-old Japanese ceramic tradition rooted in the coastal castle town of Hagi within Yamaguchi Prefecture, which has a mountainous landscape shaped by volcanic activity over eons of time. The porous clay and the milky white glaze for which Hagi ware is renowned have for centuries, served as natural materials for producing atmospheric and rustic ceramics for the tea ceremony, while modern ceramic artists have elevated Hagi ceramics to the level of art by skilfully blending traditional materials with expressive sculptural forms, surface manipulation and brushwork.

SAKA Koraizaemon XII (1949-2004), tea bowl with incised sections and scratch design, H 9.8 cm x 13.2 cm.

Saka Koraizaemon XII (1949–2004) was a highly celebrated Japanese master potter who led the historic Koraizaemon Saka kiln, one of the most prestigious lineages in Hagi ware (Hagi-yaki). Trained in painting, he was widely lauded for bridging the centuries-old traditions of the tea ceremony with contemporary artistic forms before his sudden, untimely death in 2004. This large tea bowl is a good example of his sophisticated approach to modernizing Hagi ware. Decorated with carved-out sections and comb-like patterns, the surface resembles an abstract collage painting. These textures are complemented by more traditional elements such as the slightly asymmetric form and the uneven rim.

MIWA Kyusetsu XIII (b. 1951), Fuchfuchi cup (cup of deep abundance), Yakushiji clay, Hagi glaze, and specially formulated black glaze, H 7.5 cm x W 7 cm.

A black and white cup by the renowned Hagi artist, Miwa Kyusetsu XIII poetically called “Three rounds of snow.” In contrast to the smooth surface and loquat color of traditional Hagi ware, this cup is draped with crawling white glaze over a dark, almost black clay body like thick snow clinging to earth. Born in 1951, Miwa Kazuhiro, formally known by his lineage name, Miwa Kyusetsu XIII is the third son of Living National Treasure, Miwa Kyusetsu XI (1910-2012). He is the current head of the famed Miwa kiln in Hagi town that has a history dating back to 1663. Influenced by his background in art and his time spent in the US, his works are celebrated for bridging traditional techniques with a modern artistic sensibility.

MIWA Kyusetsu XIII (b. 1951), tea bowl from the 'El Capitan' series, H 12.2 cm x W 16.9 cm.

The powerful presence of a snow-clad mountain is the inspiration for this monumental tea bowl by Miwa Kyusetsu XIII. This work is from the ‘El Capitan’ series, after the famous 914m high rock formation in Yosemite National Park in California. To capture the essence of the peak, Miwa Kyusetsu shaped the bowl from a block of clay using a Japanese sword to create the crags, then fired it for days in a wood-firing kiln. The rugged form draped in unctuous layers of white glaze evoke an image of snow clinging onto a mountain, and is a perfect example of how traditional Hagi ware can be transformed into sublime works of rustic abstraction.
