Construction has started on a 38-story, 180-m-tall office tower on a former hospital site in the red-hot Toranomon Redevelopment District of Tokyo, the Council on Tall Buildings and Urban Habitat reports, citing Japan Property Central. Targeting a 2023 completion, the 180,000-m² structure is a project of Nippon Steel Kowa Real Estate, Tokyo Gas Real Estate, Kyushu Railway Co. and Taisei Corp. Close to the new Toranomon Hills Station in an area that is "transforming into an international business hub," the tower will join others such as the recently completed, 183-m-tall Toranomon Hills Business Tower, 215-m-tall Toranomon Hills Residential Tower and the 256-m-tall Toranomon Hills Station Tower.
