Washi
Chiyogami is created by applying decoration to washi; originally, this was achieved using the Japanese method of woodblock printing. Strong and durable washi made of long fibres from the barks of kōzo (paper mulberry), mitsumata (paperbush) and ganpi (a group of native Japanese shrubs of the genus Wikstroemia), is particularly suitable for this printing method. The Haibara paper company (founded in 1806) was the first in Edo to specialize in high-quality smooth-textured washi made from ganpi, which was held in high esteem by Edo’s artists, including calligraphers, ukiyo-e painters and woodblock printers.
