The process by which original products are made

  • 1. Mold making

    1. Mold making

    Several types of plaster molds are created for use in the mass production of ceramics, including original forms, production molds, and case molds. These molds are made larger than the finished product because ceramics have the property of shrinkage during firing process.

  • 2. Forming

    2. Forming

    Mass produced ceramics are formed using plaster molds. The forming method, such as high-pressure casting or slip casting, is chosen according to the shape of the product. Only about 50 to 100 products can be made from each plaster mold because they wear down with each use.

  • 3.仕上げ


    Finishing, such as the removal of burrs from molds or finishing the mouth, is a very important process in the manufacturing of ceramic products. Products made with complex molds can only be finished by hand, and each item is worked on with painstaking care.

  • 4. Drying and bisque-firing

    4. Drying and bisque-firing

    The ceramic product is called “greenware” after finishing, and is bisque-fired (at approximately 800°C at Ceramic Japan) after being adequately dried. A company logo or underglaze decoration is applied after firing.

  • 5. Glazing

    5. Glazing

    Glazing is the process by which glaze is applied to biscuit ware to give it color and tone. Different glazes are used depending on the shape and design of each piece. Together these offer an infinite variety of finishes, from glossy to matte textures.

  • 6. Firing

    6. Firing

    Ceramic Japan primarily uses a process called reduction firing for the firing of our ceramic products. The kiln is filled with pieces one day before firing, and the products are completed after between 14 and 15 hours on the following day.

Series & Designers



Crinkle is a series of vases and tableware that recreates the look of crinkled paper bags. Our New Crinkle Super Bag was selected for the permanent collection at the Museum of Modern Art (MoMA) in New York, and is currently available for sale at the MoMA gift shop.




The Moderato series of tableware features cups in which the handle seems to flow from the body. Moderato is word from the Italian language used to mean “just the right tempo” in musical notation. The name was selected out of the designers hope that users could enjoy daily life with the items at a tempo that was neither too fast nor too slow.




This series of earthenware pots won the Silver Prize in the design category at the 9th International Ceramics Competition, Mino in 2011. The design eliminates the typical bulkiness of earthenware pots by using an indentation in the body of the pot in lieu of handles. The result is an appealing earthenware pot that can be used at any time of the year.


Still Green

Still Green

Still Green is a series of single-flower vases made to form the outline of other ceramic vessels. The name Still Green is intended to convey the idea of something starting, and the process of a new beginning. The flower vase and the act of decorating with flowers gives rise to something new simply by changing the presentation.


Still Green


This series of flower vases presents the flower and vase like a hair style and clothing. Each item appears to be a simple flower vase from one side, but from the other appears various different clothing collars at the vase’s rim. The outer surface of the series uses a biscuit or bisque finish without using glaze. The series is available in white and various colors achieved through a kneading technique which blends the dye into the raw clay.

Our Workshops

Prototype shop

In this space, blueprints received from designers are followed to form the piece out of plaster to create original forms. The white plaster gives the original form its own beauty, and when arrayed on shelves, they take on the appearance of rows of buildings or statues.

In addition to slip casting, we form our ceramic products at Ceramic Japan through a process called press molding. This space is supplied with all the necessary tools to finish the greenware into a variety of shapes after forming.

Kiln shop Kiln shop

Kiln shop

The kiln shop is where the items are prepared for firing such as bisque-firing, applying underglaze and glaze. During the final firing, the ideal atmosphere is maintained within the kiln by regularly measuring the temperature and adjusting the volume of air and gas pressure.
