On December 12, the Tokyo Metropolitan Government’s Bureau of Urban Development announced details for the Toranomon Station South District Plan. There are plans for this project to be certified under the National Strategic Special Zone, which could provide an allowance to increase the floor space for the site.
District A (Toranomon 1-17~20), which is a 1.5 hectare site directly across the street on the northern side of Toranomon Hills, currently contains several smaller buildings including the Toranomon 10 Mori Building (1966) and the Nishimatsu Building (1962). Current plans are for a 36-storey, 185m tall office building with a total floor area of 175,000 sqm. Development approval is expected to be announced in June 2015. If approved, construction will start in February 2017 with completion expected by December 2019.
