wasōbon

thumb|19th century books of Japan '''' (, or ()) is a traditional book style in Japan that dates from the late eighth century AD with the printing of "Hyakumantō Darani" during the reign of Empress Shōtoku (764–770AD). Most of the books were hand-copied until the Edo period (1603–1867), when woodblock printing became comparatively affordable and widespread. Movable-type printing had been used from the late 16th century, but for various aesthetic and practical reasons woodblock printing and hand-copied remained dominant until much later. Japanese equivalents for "book" include 本 (hon) and 書籍 (shoseki). The former term indicates only bound books, and does not include scrolls. The latter is used for printed matter only. The most general term is 書物 (shomotsu), which means all written or printed matter that has been collected into a single unit, regardless of construction.

== Book composition == Japanese books were traditionally made of washi, or Japanese paper. This durable, fibrous paper does not easily yellow or become brittle with age, which has contributed to the remarkable preservation of early books. Western-style wood-pulp paper became dominant beginning in the Meiji period (1868–1912), and washi is very rarely used for printing in Japan today.
