Takashimaya ‘Times Square’ in Shinjuku has a roof garden with an excellent view of Shinjuku and some of Tokyo landmarks. Skytree is visible on the background on this view.
South Tokyo Landmarks from left: Izumi garden Tower, Tokyo Tower, Shibaura Island, Midtown, and Roppongi hills.
A small shrine and the Cocoon tower on the background.
Meiji dori normally a very busy street, it is no so terrible before midday.
The large department store is a good reason to visit it, with the added bonus of the roof garden views.
