One of the largest redevelopments in Tokyo’s history is underway.

The project, known as OH-1 (it is located in Tokyo’s Ohtemachi business district), will consist of two high-rise buildings with 360,000 sm (3.88 million sf) of total floor space, and a landscaped public open space. The redevelopment, which covers 20,900 sm, will be adjacent to the Imperial Palace East Gardens.

OH-1’s mixed-use programming includes office space, a luxury hotel, retail, and cultural facilities. It is scheduled for completion in 2020.
