Sharebon (洒落本), which can be roughly translated as "book of manners", was a pre-modern Japanese literary genre, produced during the middle of the Edo period from the 1720s all the way to the end of the 18th century. Plots almost invariably took place in the Yoshiwara pleasure quarters, and usually revolved around the misadventures of two contrasting male archetypes, the "Tsu" or "sophisticate", and the Tanketsu or "one who only pretends at sophistication."[1] The writing had a huge emphasis on humor and dialogue, without much in the way of actual dramatic or narrative plot elements. Physically, sharebon were produced using woodblock print, and published as individual booklets measuring, on average, 4.5 inches (11 cm) in width and 6 inches (15 cm) in height. The booklets themselves containing anywhere from 60 to 100 pages. Most booklets had an illustration placed either right after the title page or along with the preface.[1] Sharebon are considered a subgenre of gesaku.
