Ee ja nai ka (ええじゃないか) was a complex of carnivalesque religious celebrations and communal activities, often understood as social or political protests, which occurred in many parts of Japan from June 1867 to May 1868, at the end of the Edo period and the start of the Meiji Restoration. Particularly intense during the Boshin War and Bakumatsu, the movement originated in the Kansai region, near Kyoto.
