The Nishi-Shinjuku 3-Chōme Redevelopment (西新宿三丁目西地区市街地再開発) is a proposed redevelopment project in Nishi-Shinjuku, Tokyo, Japan. The proposal includes 235m tall, 65-storey apartment buildings with a total floor area of 385,000 square metres (4,144,106 sq ft), along with retail on the lower floors.[2] If built they will be the tallest purely residential towers in Japan.[3] As of 2024 the development remains in the planning stage, with its expected completion being in 2029[4]
The original proposal in 1993[2] included one 77-story, 338 metres (1,109 ft) office tower; two 66-floor, 245 metres (804 ft) residential towers; and one 50 floor, 190 metres (623 ft) residential tower.[5][6] The 77-story office tower would have been Japan's tallest building, taking the title from the Azabudai Hills Mori JP Tower.[7] This proposal was canceled due to the Great Recession.[3]
