'floating/fleeting/transient world' (浮世) is the Japanese term used to describe the urban lifestyle and culture, especially the pleasure-seeking aspects, of Edo period Japan (1600–1867). culture developed in Yoshiwara, the licensed red-light district of Edo (modern-day Tokyo), the site of many brothels frequented by Japan's growing middle class. A prominent author of the genre was Ihara Saikaku, who wrote The Life of an Amorous Woman. culture also arose in other cities, such as Osaka and Kyoto. The famous Japanese woodblock prints known as, or "pictures of the floating world", had their origins in these districts, and often depicted scenes of the floating world itself such as geisha, kabuki actors, sumo wrestlers, samurai, merchants, and prostitutes. The term in medieval Japan was associated with Buddhism and meant "this transient, unreliable world". When written as meaning "the floating world", is also an ironic, homophonous allusion to the earlier Buddhist term "sorrowful world" (憂き世), referring to the earthly plane of death and rebirth from which Buddhists sought release. In its modern usage, the term is used to refer to a state of mind emphasising living in the moment, detached from the difficulties of life.
