Japanese developer Mori Building has completed the construction of Toranomon Hills Business Tower – part of the Toranomon 1-chome Type 1 City Redevelopment Project in Tokyo – and is scheduled for opening soon in April.

The 36-storey Toranomon Hills Business Tower offers some 96,000 sq m of large-scale office space and around 7,600 sq m of retail space for shops and restaurants. The building is directly connected to the new Toranomon Hills station on the Hibiya subway line, which is planned to commence partial service from 6 June 2020. It is also connected to the Toranomon station on the existing Ginza subway line.

There is a bus terminal on the first floor serving various bus lines, including the Bus Rapid Transit service that will connect to the city centre, and waterfront areas and airport limousine buses connecting the Toranomon area directly to the Haneda airport. And when Loop Road No. 2 is fully opened, it will enhance accessibility to the Haneda Airport.

A new pedestrian walkway linking the business tower and the Toranomon Hills Mori Tower has also been constructed. Together with the Shintora-dori Avenue built as a stretch of Loop Road No.2, this completes a new pedestrian network that will connect the entire Toranomon Hills area.

A sizeable incubation centre called ARCH, with an area of around 3,800 sq m, will host innovators involved in a wide range of fields and allow them to collaborate on new business ventures by large-scale enterprises. The ARCH centre aims to be a base for Japan's unique innovation ecosystem.

In order to facilitate the efficient use of energy and strengthen disaster prevention measures, the electricity plant is equipped with a private power generator complex incorporating a gas cogeneration system and a highly efficient heat generation system, which utilises large-scale water tanks and waste heat utilisation facilities - thus creating an energy supply that is environment-friendly. A back-up system that can supply electricity and heat in the aftermath of a disaster has been installed as well, contributing to the safety and security of the building.

The Toranomon Hills Business Tower was designed by Ingenhoven Architects (exterior) and Wonderwall (interior). Contractors on the project are Obayashi Corporation, Kinden Corporation, Sanki Engineering Co Ltd and Saikyu Kogyo Co Ltd.

Construction of the other buildings, Toranomon Hills Residential Tower and Toranomon Hills Station Tower (tentative name) are currently underway, which are slated for completion in January 2021 and July 2023 respectively.
