Developer Mori Building has kicked off construction on what will become Japan’s tallest tower, as part of its plans for an $8 billion three-tower urban regeneration project.
Known as the Toranomon-Azabudai Project, the large scale urban redevelopment will become a “city within a city”, and is touted by the developer as a "modern urban village located in the heart of Tokyo”.
Mori says the mixed-use city development, with a project cost of 580 billion Japanese Yen (A$8.13 billion), will comprise 1400 units.
Construction on the first of three skyscrapers started this month, with the tallest skyscraper, set to become Japan's tallest, to climb 330-metres.
The three towers, designed by US-based Pelli Clarke Pelli Architects under the direction of the late César Pelli and Fred Clarke, are slated for completion in March 2023.
Dubbed a new city-within-a-city, the developer expects up to 20,000 office workers and 3,500 residents to live and work in the precinct.
UK firm Heatherwick Studio was at the design helm of public realm and lower level architecture, while retail space was designed by Japan's Sou Fujimoto Architects.
The project is set across 8.1 hectares, an area similar to that of New York's Rockefeller Centre, and includes 24,000sq m of greenery, including a 6,000sq m central square.
The development includes plans for an international school, a 120 room hotel and 213,900sq m of office space.
The developer says 100 per cent of the electricity supplied to the neighbourhood will be from renewable sources.
Mori Building says it has plans to apply for project certification under the WELL Building Standard of the International WELL Building Institute.
The project site straddles the Toranomon 5-chome, Azabudai 1-chome and Roppongi 3-chome districts in Tokyo’s Minato ward.
