We are dedicated to hand making pottery that expresses the Japanese philosophy of wabi-sabi (finding beauty in organic imperfection).
In the Toki region, where our company is located, a unique process called "slip casting" (drained mud casting) was actively practiced due to the abundance of pottery clay. Slip casting is the practice of dumping excess mud into a plaster mold after it has hardened to a certain degree.
Our Japanese tableware is mainly earthenware pottery. We steadfastly continue this traditional handmade approach and work with the utmost care and attention. The skill and sincerity of our craftsmen can be seen and felt throughout our products.
Per the unique Japanese worldview of wabi-sabi, red clay is used, covered with a layer of clay, and fired two or three times. The pottery is unglazed two or three times before being covered with makeup clay to create subtle changes in the clay's color.
The softness and elegance of clay alone and the warmth of our craftsman's touch give these products a unique aesthetic. Even the appearance of gradual decay is sublimated to the most refined beauty...
We invite you to touch and feel the difference between our artisanal pottery versus the mass-produced items that flood the market.
- Please note that even with the same clay, technique, and glaze, the color, and size of the product may vary slightly from firing day to firing day due to differences in the amount of fire in the kiln, gas pressure, temperature, and humidity.
- Uneven glaze, flakes, pools, crazing, iron powder, and pinholes may be seen in some cases. However, these are our pottery's natural characteristics.
- A craze is a crack pattern in the glaze caused by the difference in shrinkage between the glaze and the base material during the cooling process after firing. They are often mistaken for cracks, scratches, or fissures, but they are not the same. These are not defects.
- The patterns of our pottery's glaze naturally show various expressions when exposed to light. These are natural features and highlights inherent to our methods of pottery.
• Before placing your order, you will be given the option of having us gift-wrap the items before shipping them to you.
• The wrapping paper is beautiful translucent Tosa washi with a pattern called "Seigaiha" (blue ocean waves), a gentle and auspicious wave pattern used in kimonos, dances, and Kabuki performances.
• This paper is only available in red.
• We reserve the right to change the type of wrapping paper used without notice.
• If you would like to have multiple items wrapped in one package, please indicate so in the memo field.
• If you do not have a specific request, we will prepare to wrap for multiple items separately.
• The picture of the wrapping material is meant to give an indication. Your wrapping may look different.
• Wrapping may differ for different products due to variations in their size and shape.
- Before using the product for the first time, be sure to wash it with water or lukewarm water.
- Even if the product is microwave-safe, please do not use it at high wattage, for a long time, or immediately after taking it out of the refrigerator, as it may crack or be damaged if the temperature changes too much.
- The dishwasher can be used, but please be careful not to overfill the dishwasher. If your item comes into contact with the surrounding dishes, it may be damaged.

Variations in Physical Characteristics
While we only dispatch items that have passed our quality inspection, please note that they may vary in physical characteristics.
Even if the same clay, technique, and glaze are used, the amount of fire, gas pressure, temperature, and humidity in the kiln during firing changes depending on the day. As a result, each piece's colors and dimensions can vary.
Accidental finishes caused by uneven temperatures, known as kiln changes, give individuality to the shades of color and the appearance of patterns. Thus, pottery is said to be a living thing.
There may also be glaze bleeding, drips, pooling, spattering, peeling, warping, iron powder, or pinholes. Rather than faults, these are features that make the piece unique and original.
