Tokoname’s pottery roots trace back to the Heian period (794–1185 CE), when the region’s smooth, iron-rich clay began shaping everyday vessels. By the Kamakura period (1185–1333 CE), Tokoname ware was widely used across Japan.

In the late Edo period (1603–1868 CE), the city introduced large-scale climbing kilns—the most advanced of their time. These kilns enabled the efficient firing of ceramic pipes and refined red clay teapots, laying the foundation for the Tokoname ware we know today.

One of Tokoname’s defining features is its local clay, sourced from the Chita Peninsula. Rich in iron, this high-quality clay is used to create the unglazed red surface known as shudei. By firing the clay to draw out its natural red hue—a technique developed over centuries—artisans create ceramics with a soft texture and warm, earthy tone.

The clay’s density allows it to be fired at relatively lower temperatures, and even without glaze, Tokoname ware remains water-resistant—unusual for earthenware. Over time, the surface of unglazed shudei teapots gains subtle depth and luster, making each one more beautiful with use.

Tokoname’s iconic shudei teapots have been refined over generations. Their warm, earthen hue comes from high-temperature firing of local iron-rich clay, left unglazed to preserve its natural texture. This porous surface softens bitterness in green tea, creating a rounder, smoother taste. Every teapot is hand-thrown, with precise attention to how the lid fits, how the tea pours, and how the flavor develops.

• Perfect Lid Fit
  Hand-thrown on the wheel, each lid is made to align precisely with the body, ensuring excellent heat retention.
• Unglazed Earthen Body
  Fired without glaze, the porous clay softens bitterness in green tea, creating a mellow, rounded flavor.
• Strainer Options
  Traditional sasame and ceramesh strainers are made from the same clay as the teapot and built into it, with tiny holes ideal for sencha and gyokuro. Some modern teapots use stainless-steel strainers for everyday convenience.
• Sharp Spout
  Carefully shaped for a precise pour, the spout’s angle also helps prevent drips.

Visit Gyokko Toen to see Tokoname teapots shaped with quiet precision. On the wheel, Umehara Hirotaka forms five essential parts—body, handle, spout, strainer, and lid—stripping away excess to reach refined function. Iron-rich red clay shifts in the kiln, and with use, natural oils bring a soft, lasting sheen. Guided by consistency, innovation, and “only what’s needed,” Gyokko Toen makes teaware that honors tradition and keeps Tokoname ware alive, one pot at a time.
