Prada

This fashion "epicenter," designed by Herzog & de Meuron, is one of the most buzzed-about architectural wonders in the city. Its facade is comprised of a mosaic of green glass "bubble" windows: alternating convex and concave panels create distorted reflections of the surrounding area. Many world-renowned, nearby boutiques have tried to replicate the significant impact the Prada building has had on the Omotesando, but none have been unable to match this tower. Most visitors opt for a photo in front of the cavelike entrance that leads into the basement floor. Subway: Ginza, Chiyoda, and Hanzo-mon subway lines, Omotesando Station (Exit A5).
