The 2020 Summer Olympics and 2027 opening of the new maglev line have helped to spur along some major construction projects in Tokyo, in particular the Toranomon area.
Since the opening of Toranomon Hills in 2014, the Toranomon area is quickly emerging as Tokyo’s newest hub for international business. It is not just an office area, as nearby hotels, hospitals, and serviced apartments are also in the process of being built. There are also plans for a new station along the Hibiya Line that will connect with Toranomon Hills.
Mori Building is the major player in this district, and plans to invest over a trillion Yen in projects in the Toranomon and Roppongi area over the next 10 years.

The Toranomon 2 Chome District redevelopment includes the redevelopment of the Toranomon Hospital. The new hospital will be 19 storeys with completion scheduled for 2018. A 36-storey office tower will be built next with completion in 2022. The entire redevelopment will have a total project cost of approximately 145.6 billion Yen and will be completed by 2024.

Toranomon Azabudai District

The development of public transport and pedestrian facilities is also progressing. Although this area already has several transport options, there are plans for a new station alongside the Hibiya subway line between Kamiyacho and Kasumigaseki Stations. The new station may ben open by 2020 with final completion by 2022.
