Super high rise multi-use tower as Tokyo’s new landmark

Toranomon Hills Mori Tower is a super high rise multi-use tower with 52 floors above ground and 247 meters in height comprised of offices with top-level specifications, world-class conference facilities, Japan’s first Andaz Tokyo hotel, retail facilities, residences and others. By utilizing a breakthrough system that allowed the construction of architectural structure above roads, the property was constructed integrally with the construction of Ring Road No.2. It was a symbolic project of urban development under public-private partnership.

Facility Features

Located in the center of the Toranomon area where further development is expected

  • The property is located within walking distance of Toranomon Station on the Tokyo Metro Ginza Line and Kamiyacho Station on the Tokyo Metro Hibiya Line, and six stations and 11 routes are nearby.
  • It boasts excellent access to the administrative district in Kasumigaseki as well as major business districts in Tokyo such as Marunouchi, Hibiya and Ginza.
  • As a result of a number of redevelopment projects currently in progress around the building and a nearby new station on the Tokyo Metro Hibiya Line is scheduled to start the service in 2020, the Toranomon area has begun to rapidly evolve into an international urban center.

Luxury-grade office environments and ample facilities

  • Office floors from the 6th to the 35th provide a leasable area at an average size of approx. 1,000 tsubo, providing flexible workspaces with a ceiling height of 2.8 meters.
  • The property has three types of high seismic capacities and boasts a well to be used at the time of earthquake disasters and an emergency power generator – a measure that ensures business services can resume under any conditions.

Biodiversity-conscious open spaces

  • In the open space of about 6,000 m², there is the “Oval Plaza” garden that serves as an oasis in the city with the comfortable sound of a stream, and the “Step Garden” with greenery that provides an enjoyable seasonal atmosphere, that together form a rich urban space where people can gather.
