Upsetters is a reggae music bar in Nakasu, Fukuoka. The DJ booth plays Ken Boothe tracks and 1970s and 1980s dancehall, and the bar serves mojitos and habu-shu. The owner and his wife run the place, and a photo of Marcia Griffiths hangs on the wall. Bar seating can be designated members-only, and there have been reports of staff suddenly getting angry at customers.
