There were fifty teahouses, sixty geisha and apprentice geisha, and three shogi (prostitutes) in Kamishichiken before World War II, but the war forced most of the teahouses to close down or change their business; however, some of them reopened their teahouses around 1945.
上七軒は戦前まではお茶屋50軒、芸妓、舞妓あわせて60名で娼妓も3名いたが第二次世界大戦でお茶屋の大半が転廃業し、1945年ごろに再開。
