More than 1000 varieties of tropical and subtropical plants grow inside this 1500-square-meter dome-shaped greenhouse located in a park next to Tokyo Bay. Some highlights include giant water lilies, jade vines, Chinese banyan trees, flowering hibiscus plants and assorted orchids. A separate greenhouse area is home to a collection of carnivorous plants from around the world, and the outdoor herb garden grows more than 100 kinds of herbs.

The cafe area serves casual cuisine with a tropical theme, such as Haitian curries, but they tend to run out of food before closing time. There's also a gift shop selling potted plants and tropical-style snacks. Near the greenhouse you'll find popular picnic areas and a very active marina.
