Yumenoshima Park is a sprawling green space built upon a reclaimed island in Tokyo Bay, originally developed as a waste disposal site. The park serves as a major recreational hub featuring extensive sports facilities, including an archery field that hosted events during the 2020 Tokyo Olympics. It houses the Yumenoshima Tropical Greenhouse Dome, which showcases diverse equatorial plant species under a glass structure. Large lawns and open fields provide space for athletics and outdoor activities. The park is characterized by its transformation from an industrial site into an ecological and sports-oriented public space. It offers elevated views of the surrounding bay and the Tokyo skyline.
