Shibuya Sky is an open-air rooftop 230 metres up, no glass between you and the horizon, with the Scramble crossing pulsing directly below and Mount Fuji on the skyline when the air is clear. Book the slot an hour before sunset and you get daylight, golden hour and the neon switch-on in a single visit.
Sunset slots sell out days ahead, book online early. Tripods are banned and phones need both hands at the edge; the wind up there is real. Cloudy-day tickets are the quiet bargain, the neon needs no weather.
The rooftop crowns Shibuya Scramble Square, directly over Shibuya station. Ride down, walk the crossing you just watched, and let the night start from there.
