The construction of many facilities in Tokyo Waterfront City for the 2020 Olympics will have great significance for the future urban structure of Tokyo. The ring-shaped structure of Tokyo and its adjacent neighborhoods is nearing completion with the development of the Waterfront. The Olympic facilities that were built on the Waterfront, which was a blank area of the ring-shaped city structure. The emblems selected for the 2020 Olympics in a newly-held competition are embedded with a message of “diversity and harmony” for the Olympics and Paralympics, defining it as a venue where the world can connect and diversity will be mutually accepted. From here, I hope discussions transition to the more essential topic of what we can leave behind for the next generation through the 2020 Olympics. One of the reasons why Tokyo is not isolated even if it conflicts with the national government is that it is structurally integrated with neighboring prefectures through the metropolitan area concept. Tokyo has the same interests as neighboring Kanagawa, Saitama, Chiba and Ibaraki in terms of economy and living. It is hoped that the Tokyo Metropolitan Government will continue to extend its unique policies to the country, both politically and administratively.
