washi

Washi is characterized by its long fibers and durability, making it significantly stronger and more translucent than standard wood-pulp paper. It is primarily associated with traditional Japanese craftsmanship and is often used in calligraphy, screen doors (shoji), and high-end art restoration.

As a material noun, it is typically treated as uncountable when referring to the substance itself. While one might refer to "sheets of washi," the word generally describes the medium rather than individual items.
