In light of the recent heavy rain disasters occurring in various parts of the country, the Bureau of Construction, the Tokyo Metropolitan Park Association (a public interest incorporated foundation), and private businesses (expansion tour partners) will collaborate to hold an infrastructure tour of the Kanda River and Route 7 Loop Underground Regulation Pond (hereinafter referred to as the Loop 7 Underground Regulation Pond) to help Tokyo residents understand the purpose and effects of river facility development.
We are planning various tours and events that incorporate tours so that more people can learn about river facilities. We look forward to your participation in a tour of the huge underground tunnel, which is normally off-limits to the public.
