Background of the Redevelopment Project

The Azabudai Hills site encompasses a long, narrow district running from east to west, originally broken up by hills and valleys in a convoluted terrain. The fragmented district was populated with small, old wooden houses and buildings, many of which were deteriorating. Overall the city infrastructure was in need of an upgrade.
Mori Building and local residents therefore resolved to address these problems, update the area's infrastructure such as roads and parks and improve the safety and security levels, all by means of a Type-1 Urban Redevelopment Project under the Urban Renewal Act.
The Council of Redeveloping Cities was established in 1989. Since then, in collaboration with some 300 landowners representing different positions and circumstances, the Toranomon-Azabudai area was discussed and planned over more than 30 years. In 2017, the City Plan was approved based on the Law of National Strategic Special Zone, and following approval of the establishment of Toranomon-Azabudai District Urban Redevelopment Association, construction began on August 5, 2019. It opened in Novenber 2023.
