THE rice bowl is designed with human hand in mind: the 12 centimeter diameter of the rice bowl is derived from the average diameter of a Japanese person’s hand when a half-circle is made with the thumb and pointing finger. In other words, it is the perfect size that naturally fits a hand.
The height is set at half the diameter, which is 6 centimeters, as the ratio between the pointing finger and thumb is said to be exactly 2:1.
Once the shape is defined, THE rice bowl is made in five different regions of Japan that are known for their distinct pottery styles, in order to offer a comprehensive view on Japanese pottery's various expressions: the styles include Arita (Saga Prefecture), Kiyomizu (Kyoto Prefecture), Shigaraki (Shiga Prefecture), Seto (Aichi Prefecture), and Mashiko (Tochigi Prefecture).
To enhance and emphasize the characteristics of each style, the clay, glaze, and finish are all white-colored.
ARITA (Saga Prefecture)
Arita is a region known to first discover kaolin in Japan 400 years ago. Arita-yaki porcelain has been widely recognized in and out of Japan, being extensively exported to Europe between the 17th and 18th century as “Imari” and was traded with a value equivalent to gold. The transparent complexion of white that is distinct in Arita porcelain is a result of the exquisite craftsmanship, and met the high demand to the Dutch East India Company. Arita's rice bowl is finished with the “Hishaku-Gake” (Ladle-pouring) glazing technique.
