For one of the best free experiences in Tokyo, head up to the observation decks of the Tokyo Metropolitan Government Building. From 202 meters up, you'll get a stunning panoramic view of the city's sprawling landscape. On a clear day, you might even be lucky enough to spot the majestic Mount Fuji in the distance. It's a fantastic way to get your bearings and appreciate the sheer scale of Tokyo, especially as the city lights begin to sparkle at dusk.
