Hagaki Paper

In Japan, Hagaki card paper is traditionally crafted from 100 percent kozo bark. Kozo is a type of mulberry plant that is native to Japan, China and other countries throughout Asia. The bark of this plant is strong and durable, making it ideal for use in cloth and papermaking.

Genuine kozo hagaki cards can be found at many specialty paper stores online. One of the more popular varieties of the paper is Etchu Hagaki, which is named after the region in Japan where it is made. The Etchu Province, which today is known as the Toyama Prefecture, is one of the oldest papermaking regions in Japan, and it produces some of the highest-quality kozo hagaki card paper.
