Completed in 1967, architect Kenzo Tange's iconic building served as the headquarters for Dentsu, then the world's biggest advertising agency, until 2002. After that it was occupied by Dentsu Tec, a subsidiary company, until 2014; it is now vacant.

The building stands thirteen stories tall, with two additional penthouse levels. It was originally designed as part of a grand urban-planning scheme for the Tsukiji neighborhood, where a grid of high-rise buildings would be connected by elevated bridges. Unfortunately the original design was watered down quite a bit, and this was the only part of the master plan that was actually built.
