Folding fans, known as , or , remained the dominant accessory within the realm of the sophisticated court culture prevailing in Kyoto at the time. 
Historically, were an ostensibly feminine accessory, with men more typically carrying folding fans. They were simultaneously fashion accessories and functional items for daily use. They are strongly associated with summer, having been sold only during the summer months, and often decorated with summer imagery. At least one critic argues that, due to their use by women during periods of intense heat, "can have suggestive connotations."

More ceremonially, they can still be seen in a number of contexts, including a variety of summer dance performances and as an accessory carried by referees during sumo matches.
history.
 with printed designs were first produced in Japan sometime in or prior to the 1680s. One of the earliest extant examples is a 1684 by entitled , which includes illustrations within fan-shaped frames. Other notable examples placing within a socio-historical context are prints by from 1767 or 1768 featuring (fan sellers), and an 1814 print by Utagawa Kunisada depicting kabuki actor Ichikawa Dannosuke II in the role of a fan vendor.
One historical fan vendor whose life is well-recorded is . Ebiya printed and sold both fan and standard-sized prints until around 1895. Although Ebiya's publishing house originally commissioned designs from Utagawa Kunisada and Utagawa Kuniyoshi exclusively, they expanded their roster to include other artists from the late 1850s.
