This branch of a generic national karaoke chain was immortalised as a location in the film Lost in Translation. Another draw: the rack of costumes in the lobby you can borrow for free. Sing all night from 11pm to 5am for just ¥1990 Monday to Thursday (or ¥2850 Friday to Sunday). Ask at the desk about all-you-can-drink (nomihōdai; 飲み放題) plans.
During the week before 7pm rates drop to ¥120 per 30 minutes.
