The greenhouse houses a diverse collection of tropical herbs, shrubs, and trees. Some species are quite rare, and some are in danger of extinction. Visitors are asked to please stay on the walkway, not to pick the flowers or take cuttings, and to be careful not to damage the plants as you pass by. We hope you will enjoy your visit while also trying to keep the greenhouse clean and attractive for others to enjoy.
Greenhouse Guide
The greenhouse contains a wide range of tropical plants from all over Japan, including the Ryukyu and Ogasawara Islands, as well as a collection of rare and endangered species.
Tropical Lowland Plants
The plants here are those that people normally associate with the term “tropical” — such as those species that thrive in dense rain forests.
Ogasawara Area
The Ogasawara Islands lie 1,000 km south of mainland Japan in the Pacific Ocean, and are officially part of Metropolitan Tokyo. These volcanic islands are isolated and support a unique flora.
Desert Plants
This section displays plants adapted to arid environments, such as cacti and other succulents.
Okinawa Area
The Ryukyu Islands stretch more than 1,000 km between Kyushu and Taiwan. Several times in the past these islands have been connected to the Asian mainland, and their unique flora contains many species that originated on the continent but later evolved separately.
Tropical Pond/Marsh Plants
Many tropical and subtropical plants live in water habitats such as ponds or marshes. This exhibit features examples of familiar aquatic plants, such as lotuses, that thrive in warm climates.
Familiar Tropical Plants
This area features tropical plants with flowers or fruits that are very familiar.
Site of Old Greenhouse
The old greenhouse was built in the 1890s and frequently remodeled. This site shows part of the foundation of the old greenhouse, which was excavated during the construction of the current building.
Special Exhibition Room 1
The greenhouse is famous for its collection of orchids and orchid seeds. Room 1 contains an exhibit of endangered varieties of these beautiful flowers, including the original collection from over a century ago.
Special Exhibition Room 2
This room contains a very special collection of endangered species from Ogasawara Islands that is cultivated here at the greenhouse.
Tropical Mountain Plants
Tropical climates are not all rain forest. There are also cool, high-altitude areas in the tropics, which is the source of, for example, coffee beans.
