Bike tours are a great way to stretch your legs and see Tokyo. Freewheeling Japan tours the cobbled old town of Yanaka to the Meiji Shrine or Setagaya Park -- depending on the day's itinerary.

In beautiful weather, spend the day relaxing in Yoyogi Park in Shibuya, which hosts music performances and plenty of head-turning fashions.

Local tour company Walk Japan will make the experience much more digestible, thanks to its well-organized walking programs that highlight a mix of must-see spots and less-frequented neighborhoods.

Need a cocktail recommendation? The Palace Hotel's Lounge Bar Prive is home to a terrace with views of the Imperial Gardens and Tokyo skyline.
