Brief History of Shiroishi Washi

In Edo period (1603-1867), the then shogunate, Kojyuro Katakura, actively promoted the Washi-making industry to improve the economy.

In Meiji period (1867-1912), the hand-made Washi industry declined because of mechanizations and import of paper. In additional, Shiroishi Washi is not suited to be machine-made, so only few families continued to make Shiroishi Washi.

Now only one family continues to make Shiroishi Washi. Because of its high quality, the Washi is used in many important events, by artists and many dignitaries including the Japanese emperor.

Different Uses of Shiroishi Washi

"Omizu-tori" is an event that monks practicing asceticism acknowledge their misdeeds and reform in the most famous temple "Todaiji" in Kyoto. In this event, monks wear holy clothes made of Shiroishi Washi.

When the Washi was used to record the Japanese Instrument of Surrender ending the Second World War, it is said that Admiral MacArthur Douglas wished for peace that could last as long as the Washi.
