Kōka

Kōka (弘化^?) was a Japanese era name (年号,, nengō,^?, literally "year name") after Tenpō and before Kaei. This period spanned the years from December 1844 through February 1848. The reigning emperors were Ninkō-tennō (仁孝天皇^?) and Kōmei-tennō (孝明天皇^?).

The nengo was not changed concurrent with the accession of Emperor Komei; instead, the Kōka era was retained until about a year after the new emperor was enthroned.

During these years, Hiroshige began making a series of prints showing beautiful women in contexts of famous places.
