Japan Post Tower

Tokyo, N/A / Japan

The high-rise corporate headquarters is built on, and adjacent to, the historical Central Post Office site, which was preserved, next to the busy Tokyo Marunouchi Station, in the heart of the city. The new tower incorporates the existing façade as the base of the building and into a retail galleria which becomes the interface to the urban scale of the adjacent plaza. The tower integrates the lines of the existing building within its facade creating continuity between the two parts.

The volume of the tower steps back from the original building, which becomes the podium that defines the site boundary, allowing for the creation of a roof-light and a roof garden on it. The public roof terrace creates a relaxing space within the heart of downtown and in which you can admire the ever changing urban scene of Tokyo Station and its surroundings. The origami-wall characterizes the building's north elevation and brings a unique sculptural character to the Post and surrounding urban area.
