No trip to Tokyo is complete without indulging in a little kitsch and karaoke. Rainbow is as much a spot for veteran would-be superstars as it is for shy-to-sing novices. Many of the rooms have full band kits—drums, guitars, speakers—while others are cozy and private enough for guests coming to sing solo. It’s a stone’s throw from Shibuya station, so it’s easy to get to. The courage issues that alcohol can’t help, sugar might—hence the free ice cream at reception.
