The greenhouse was established in 1988 in Yumenoshima ("Dream Island") Park, a reclaimed landfill and dumping ground in Tokyo Bay. Its three domes currently contain about 1,000 species of tropical and semitropical plants. The A Dome features rain forest with ferns and waterfall, B Dome represents a tropical village, and C Dome contains vegetation of the Ogasawara Islands. There is also a small carnivorous plant room.
