For one of the most breathtaking perspectives of the city, you have to head up to Shibuya Sky. It's an open-air observation deck that gives you an incredible 360-degree panorama of the entire Tokyo skyline. Time your visit for just before sunset; watching the city lights begin to sparkle as daylight fades is a truly unforgettable experience. On a clear day, you can even see the iconic Mount Fuji in the distance.
