Prada Aoyama (プラダ青山店)

Designed by Swiss architects Herzog and de Meuron, this eye-catching glass building has become an iconic landmark in the swanky Aoyama district since its launch in 2003. This asymmetrical building created out of diamond-shaped glass panels is especially beautiful after dark, when the luxe interior (and designer goods) can be seen from the outside through the green glass. It certainly gives new meaning to the term window shopping.
