Umi Tea Sets Tokoname-yaki Tea Cup

Tokoname-yaki is one of Japan's six ancient kiln traditions, known for using iron-rich clay from the Tokoname region. This specific clay is prized for its density and ability to retain heat, which helps maintain the temperature of your tea or coffee longer than standard ceramic mugs.

While the clay is durable, we recommend hand-washing this piece to preserve its unique, rustic finish and texture over time. We also advise against microwave use, as the iron content in the clay can react unpredictably to rapid temperature changes.

Tokoname-yaki clay is naturally porous and mineral-rich, which many tea enthusiasts believe softens the water and enhances the flavor profile of green teas. While it works beautifully for coffee as well, the material is particularly celebrated for its ability to smooth out the astringency of Japanese teas.

Yes, 8.8 ounces is a standard size for a generous cup of tea or a medium-sized coffee. It is designed to be a comfortable, everyday vessel rather than a large travel mug.

The cup features a wide, ergonomic handle specifically designed to keep your fingers away from the heat of the vessel. While the clay retains heat well, the handle remains comfortable to grip even when the cup is filled with hot liquid.
