Tokoname Ware: Japan's Oldest Kiln and Its Red-Clay Teapots
Tokoname, on the Chita Peninsula in Aichi Prefecture, holds two records among Japan’s Six Ancient Kilns: the oldest continuous production history and, historically, the largest output. What it’s best known for today, though, is a much smaller product than the large jars that built its reputation.
The oldest and once the largest of the six
Tokoname’s pottery tradition dates to around 1100 CE, in the late Heian period, drawing on techniques from the nearby, earlier Sanage kilns. It grew into the largest of the Six Ancient Kilns and directly influenced the development of both Tamba and Shigaraki ware, whose potters drew on Tokoname’s methods and reputation as their own traditions took shape.
Why the clay itself matters
Tokoname’s clay comes from sediment left by an ancient lake that existed in the area roughly 650,000 to 1 million years ago, and it’s unusually rich in iron. That iron content gives Tokoname ware its distinctive red-brown color and let potters fire it at comparatively low temperatures. Traditionally, that made the clay ideal for large storage jars and everyday pots, built using himozukuri, a coiling technique that stacks ropes of clay rather than throwing a piece in one motion.
From storage jars to teapots
Tokoname’s modern reputation rests on a much smaller object made from the same clay: the unglazed kyusu. The same iron content that once suited large jars is now credited with softening green tea’s bitterness during brewing, and Tokoname kyusu are widely regarded as Japan’s benchmark teapot for that reason. Our guide to best Japanese tea sets covers a genuine Tokoname piece and what makes its format different from an everyday teapot.
An unexpected industrial chapter
Tokoname’s story doesn’t run in a straight line from storage jars to teapots. During Japan’s rapid industrialization in the Meiji and Taisho eras (1868 to 1926), the region became a major supplier of ceramic pipes, tiles, and other architectural and sanitary ceramics, earning a reputation as a “ceramic pipe city” as demand grew for infrastructure like railroads and sewage systems. That industrial output reached an unexpected landmark: the outer walls of the Imperial Hotel Tokyo, designed by American architect Frank Lloyd Wright and completed in 1923, were built using Tokoname tiles. Walking through the city today, retaining walls built from old ceramic pipes and discarded liquor jars, along a route locally called Dokan-zaka, “Pottery Pipe Hill,” are a visible remnant of that era.
Tokoname’s other famous export: lucky cats
Since around 1950, Tokoname has also been Japan’s leading producer of maneki-neko, the beckoning lucky cat figurine seen in shop windows across the country. The city leaned on the same slip-casting and kiln infrastructure it had built for tableware and storage jars to mass-produce the figures once demand grew, and it now marks that identity with a landmark: a concrete cat statue over 12 feet (3.8 meters) tall, peering over a wall in the city, nicknamed Tokonyan.
Frequently asked questions
Why is Tokoname considered the oldest of Japan's Six Ancient Kilns?
Its pottery production dates to around 1100 CE, in the late Heian period, earlier than the other five kiln regions in the group, and it was historically the largest of the six as well.
Why is Tokoname clay red?
It comes from sediment left by an ancient lake that existed roughly 650,000 to 1 million years ago, and that sediment is unusually rich in iron, which gives the fired clay its distinctive red-brown color.
Why are Tokoname teapots specifically recommended for green tea?
The clay's iron content is widely believed to soften green tea's bitterness during brewing. This is a well-established view among tea drinkers rather than a rigorously proven scientific mechanism.
What did Tokoname produce before it became known for teapots?
Large storage jars and everyday pots, made using a coiling technique called himozukuri, taking advantage of the same iron-rich clay that today's teapots use.
Did Tokoname ever make anything besides tableware?
Yes. During Japan's Meiji and Taisho-era industrialization, Tokoname became a major producer of ceramic pipes and tiles for infrastructure like railroads and sewage systems. Its tiles were even used on the outer walls of Frank Lloyd Wright's Imperial Hotel Tokyo, completed in 1923.
Is Tokoname known for anything besides pottery and teapots?
Yes, maneki-neko lucky cat figurines. Tokoname has been Japan's leading producer of the beckoning cat statue since around 1950, and the city has a landmark cat statue over 12 feet tall as a result.
The short version
Tokoname is the oldest of Japan’s Six Ancient Kilns, dating to around 1100 CE, and was historically the largest, shaping both Tamba and Shigaraki. Its iron-rich clay, once used for large storage jars, is now best known through unglazed kyusu teapots, widely credited with softening green tea’s bitterness. The same production base has also made Tokoname Japan’s leading maneki-neko producer since the mid-20th century.
