The facility is powered partly by residual heat generated from the nearby Koto Incineration Plant.
The site sits on Yumenoshima, an artificial island that was formerly a major waste disposal site for Tokyo between 1957 and 1967.
The three domes vary in size and climate control, collectively housing over 1,000 species of tropical plants.
The domes are designed to symbolize a 'dream island,' reflecting the literal translation of Yumenoshima.
The garden features a permanent exhibition of the 'Coco de Mer,' a rare palm species known for producing the largest seed in the plant kingdom.
The Yumenoshima Tropical Greenhouse Dome is a botanical facility in Koto, Tokyo, housed beneath three distinct glass domes that mimic a tropical environment. It functions as a research and educational center, focusing on plant life from tropical and subtropical regions. The domes maintain a controlled climate to support a diverse collection of exotic flora, including large palm trees and rare orchids. Water features, including waterfalls and ponds, are integrated into the garden design to maintain humidity and aesthetic harmony. The facility is situated within Yumenoshima Park, a large green space reclaimed from a former landfill site. Visitors can explore various climate zones within the glass enclosures, which represent different habitats. The site is a significant example of architectural integration with horticultural displays in urban Tokyo. It remains open to the public year-round, barring scheduled maintenance days.

The interior is significantly more humid and warmer than the outside temperature, so dress in layers to adjust accordingly.
Visit the secondary exhibition hall to view historical items and educational displays about the island's reclamation history.
Utilize the outdoor courtyard area if you need a break from the high humidity inside the greenhouse domes.
Do not mistake the nearby Yumenoshima Marina for the entrance to the botanical gardens.
Closed on Mondays. If a public holiday falls on a Monday, the facility is closed the following day.
Avoid touching the plants or straying from marked paths to protect the delicate tropical ecosystems.
