Don Ed Hardy Byobu (literally "wind wall") are Japanese screens with decorative paintings and calligraphy, used to separate interiors, and enclose private spaces, amid other uses. As many Japanese arts and crafts, folding screens originated in China, as prototypes dating back to the Han dynasty were found. The term meant figuratively "protection from wind", which suggests that the original purpose of byobu was preventing the wind from blowing in the rooms. Byobu were introduced in Japan in the eighth century, when Japanese craftsmen started making their own byobu, highly influenced by Chinese patterns. Through different Japanese eras, Byobu evolved in structure and designs, along with the tech- niques and materials used. The Don Ed Hardy designed screens begin with original Ed Hardy Sumi-ink paintings which are then built into screens by master craftsmen.
