A type of Japanese porcelain.
Buttons are often realistics with colorful glazes.
The finish generally has a dark color satin gloss rather than a shiny glaze. A wide range of subjects include the Seven Gods, animals, and flowers. Many of the square or rectangular plaques are also found set in metal jewelry findings as well as buttons. Most are small and have a color border. They are usually white and one other color, such as black or red.
