"Japonisme was the fad for all things Japanese that pervaded French art and design in the second half of the nineteenth century.

"From the 1850s onwards, objects from Japan flowed into the west and attracted the attention of both artists and collectors. The Paris Exposition Universelle of 1867 brought an influx of more things Japanese, as well as Japanese visitors to the city. The term "japonisme" was coined in 1872 by Philippe Burty, a French art critic, to describe what was essentially a new field of study - the influence of Japanese style on French art."
