The design of Gap's new retail flagship store in Tokyo's Ginza district applies the concept of the “White Box in the Blue Box"; Gap’s blue square becomes an architectural icon. With a striking corner facade clad in laminated blue glass, GAP occupies four floors of a new office tower. Natural light permeates the ground floor retail space and walls of etched glass softly reveal the light and activity of the street outside, while a honed limestone floor softens and warms the material palette. Navigating the upper floors, the interior escalators become a signature element, emitting a deep blue glow that subtly attracts and guides shoppers throughout the four-story building.
