Offices—from the 5th to 36th floors—provide a total working space of some 96,000m². Standard leasable space on each floor is about 3,000m² and features expansive pillar-free spaces. Floor-to-ceiling windows ensure naturally lighted open-air spaces and support flexible office layouts to accommodate diverse working arrangements.

An underground pedestrian walkway connects the Tower directly to the Toranomon Hills Station on the Hibiya Subway Line and the existing Toranomon Station on the Ginza Subway Line. A bus terminal on the first floor is the departure and arrival point for airport limousine buses and the Bus Rapid Transit service connecting central Tokyo and waterfront area. In addition, once Loop Road No. 2 running under Toranomon Hills is fully opened, it will be possible to reach Haneda Airport by road in 25 minutes. Such convenience is ideal for global companies.
All leasable space has already been leased to Japanese and foreign companies representing a wide range of industries. With the launch of Toranomon Hills Business Tower, the total office area of the Toranomon Hills complex has expanded to approximately 195,000m².
ARCH Incubation Center
The 3,800m² ARCH incubation center on the fourth floor is a new business-creation base in the Toranomon Hills, designed to serve as global business center.

The center offers a range of support services, including various sector know-how, educational programs and enlightenment events. In addition, consultants experienced in creating new business opportunities at large enterprises help facilitate collaboration between resident companies with the aim of supporting new business development.

In particular, it enables residents to leverage the abundant resources of established large enterprises, including their human resources, goods, capital and know-how. It also supports initiatives for internal business reforms as well as new business creation.
By linking with various international networks, ARCH is destined to become a bridge between diverse industries and enable innovation originating in Tokyo to permeate throughout Japan and overseas.

Architectural Design and Public Art
The Business Tower’s exterior design was created by German architect Christoph Ingenhoven (ingenhoven associates). The building is harmonized with the existing Toranomon Hills Mori Tower and serves as an international business hub. The retail facilities and ARCH incubation center, designed by Masamichi Katayama (principal of Wonderwall inc.), are highly modern and yet reflect the history and traditions of Toranomon.
Public art works by three globally noted Asian contemporary artists are displayed at office entrances and additional venues.
New Energy Network
A plant supplying electricity and heat to the Toranomon Hills complex is located on the third basement floor. To ensure efficient energy use, eco friendliness as well as disaster resiliance, the plant has a private power generator complex incorporating a gas cogeneration system and a highly efficient heat generation system that utilizes large-scale water tanks and waste heat utilization facilities. A back-up system capable of supplying electricity and heat in the wake of a disaster is also available, contributing to the safety and security of this global business center.
