Yumenoshima Tropical Greenhouse Dome, Tokyo
This large greenhouse complex in Tokyo was originally built on land reclaimed from a landfill and dumping site. It is powered by a nearby incinerator. There are actually three domes and an additional exhibit space where rare species of carnivorous plants are housed. Highlights include a fern forest, an indoor waterfall, a tropical village, orchid gardens and habitats from the sub-tropical Ogasawara Islands, one of Japan's southernmost archipelagos.
The park that encircles the dome has a large collection of cherry trees, which put on a show of blooms in early spring. An interesting niche museum that explores the after-effects of the 1950s nuclear bomb tests on Bikini Atoll sits adjacent to the greenhouses.
