Shibuya Scramble Square is a shopping mall connected to Shibuya Station and a complex cultural space that includes the Shibuya Sky observation deck. Visitors can browse small goods and luxury brand stores, then look down over the Shibuya Scramble Crossing and Tokyo's skyline. Shibuya Sky operates by reservation, so you must book your preferred time slot before visiting. The restaurant floor has waits so long on weekends that eating within an hour is difficult.
