The Tokyo Metropolitan Government, after discussing with relevant organizations, formulated the “Iidabashi Station Area Infrastructure Development Policy” in April 2023 as a guideline for improving and strengthening urban infrastructure such as roads, train stations, and concourses around Iidabashi Station in coordination with urban development around the station. Furthermore, with the aim of making the contents of this infrastructure development policy more concrete, the “Iidabashi Station Area Infrastructure Development Promotion Council” was established in May 2023 and has been proceeding with the discussions.
We have now compiled the infrastructure development plans that were concretized within the infrastructure development policy into an infrastructure development plan, and are now inviting comments from Tokyo residents as detailed below.
