Paper mulberry is the most common material used for Japanese paper. Paper made from koi is robust and easy to handle even when wet. It is commonly used for traditional Japanese interior doors, such as shoji (sliding blind doors) and fusuma (cupboard doors). Even though it is thin, it is firm and sturdy, making it ideal for painting, preservation, and restoration.
This is beautiful paper with vivid patterns on it, utilizing the same techniques and factories that pattern kimonos. The craftsman colors it with a hand mold, adding one color at a time.
This paper is decorated with patterns using various techniques. There is Unryu paper, which is made of rough fibers, Chili paper with added mulberry bark, and Ruisuisuisi paper, which is decorated with polka dots using water drops.
