Commitment to Our Products:

The "Shiki" series coasters are crafted using our tile-making technology, with the tiles exhibiting water-absorbing properties to soak up water droplets.
The Gazen series of tableware also leverages the same tile-making technology, but in this case, the water absorbency is minimized by baking the tableware at an extremely high temperature, forming an oxidized film.

The history of Yamai Manufacturer began more than 60 years ago when the previous president, Shinichi Ito, became involved in the manufacture of Shinto and Buddhist ritual objects at Yamai Manufacturer, a Mino pottery kiln in Toki.
After the establishment of Yamai Manufacturer, the company began to manufacture sake cups, earthenware bottles, soy sauce jugs, and other products as its main items.
The soy sauce jug, in particular, was the first Mino ware pottery to be commercialized.
Even now, it remains a popular product of our company along with sake cups and other items.
Entering the age of 2025, we added flat plates, mugs, and other products that can be widely used in daily life to our product lineup. From traditional to modern, we continue to explore the possibilities of ceramics.
Mino ware is a generic term for ceramics produced in the eastern region of Mino Province (present-day Gifu Prefecture) and is recognized as a traditional craft.
Mino ware has a long history, dating back more than 1,300 years. It is said to have developed from Sue ware in the Nara period (710~794).
After the Momoyama period (1573~1603), when Oda Nobunaga, Toyotomi Hideyoshi, and others established the rule of Japan, various shapes and colors of pottery were produced under the guidance of Sen no Rikyu, tea master and military commander Furuta Oribe, and others. Oribe Furuta's ingenious "Oribe-favorite" pottery is very famous.

The Tono region has been blessed with important resources for producing ceramics, including high-quality clay such as Mokubushi clay and Kagaome clay, and abundant water from the Toki River.
It has flourished as one of Japan's representative ceramic production centers, with various techniques developed following the times.
