The Acty Shiodome is a 190-metre, 56-storey residential skyscraper in the Shiodome area of Minato-Ku, Tokyo, Japan. It was constructed between April 2000 and February 2004, and is currently the second tallest residential building in Japan.[1] The building has a nickname of "La Tour Shiodome", which is actually the name of the private luxury units on the top floors. The building has a total of 768 units, with 683 rental units between the 3rd and 44th floors, and 85 private luxury units on floors 45 to 56. The building is owned by the Urban Development Corporation, part of the Urban Renaissance Agency. Floors 45 to 56 are offered for rent through Urban Development Corporation's "Private Enterprise Rental Housing System".[2] The first two floors contain shops, a day care centre, and medical clinics. The JR Yokosuka Line passes directly under the building, which is flanked by the Yurikamome New Transit line on the west and south sides, and the Shuto Expressway on the east.
