Kabukicho is the red-light district of Tokyo. It’s best to just stumble around here and head to the bottom of the hill. Ignore the sidewalk barkers and bring a lot of cash (prices have a way of expanding). You needn’t engage in anything objectionable: You can cruise pachinko parlors, see robot dance shows, visit the Samurai Museum, and see the Hanazono Shinto Shrine. If you get hungry, there are snacks galore on Omoide Yokocho, or “Piss Alley.” You’d be well-advised to drink beer throughout this entire visit.
