A true classic, the Tokyo Tower is a must-see for its incredible city views. Head up to the observation decks for a stunning panorama of the sprawling metropolis; on a clear day, you might even catch a glimpse of the majestic Mt. Fuji in the distance. While you can take the elevator, for a bit of a workout and a unique experience, try climbing the 600-step open-air staircase to the main deck. It's a fantastic way to feel the sheer scale of this iconic structure.
