Karaoke Rainbow

in Shibuya & Shimo-Kitazawa

This is Shibuya's most popular karaoke spot for two reasons: it doesn't have the same dated look as the generic chains and you get the first hour free (though, technically, you need to buy one drink; from ¥475). Staff speak some English and the English song list is extensive. It's on the 8th floor of the building with the Marui department store.
