The facility uses a centralized climate control system to maintain a constant tropical temperature throughout the year despite Tokyo's temperate climate.
The greenhouse is designed with a high-ceiling glass structure to accommodate mature, large-scale tropical trees that would not survive outdoors in Tokyo.
The aquarium collection features specific species endemic to tropical river systems, differing from standard saltwater marine parks.
The museum conducts regular research and preservation programs for rare tropical plants and endangered aquatic species.
The facility includes an educational zone dedicated to explaining the relationship between tropical rainforests and global atmospheric health.
The Itabashi Botanical Garden, officially known as the Itabashi Tropical Environment Museum (Nettaikan), is a unique facility combining a multi-story indoor tropical greenhouse with a specialized aquarium. The greenhouse features a climate-controlled glass dome that simulates a rainforest environment, housing hundreds of tropical plant species, including towering palms and various orchids. The lower levels function as a public aquarium, focusing specifically on tropical fish and marine life sourced from the Amazon River and surrounding Southeast Asian ecosystems. A elevated walkway allows visitors to observe the canopy layers of the greenhouse flora from a higher perspective. The facility is managed by the local municipal government and serves as a center for both environmental education and local biodiversity conservation. It is situated within the larger Akatsuka Park complex.

Bring a camera with a macro lens, as the exotic flowers and tropical fish are highly detailed.
Layer your clothing; the interior is kept very warm and humid, while the outdoor weather may be cool.
Visit during the weekdays to avoid crowds and have a better opportunity to view the aquarium tanks without obstruction.
Avoid rushing through the elevated canopy walkway, as this is the only way to see the top-tier vegetation.
Closed on Mondays (or the following day if Monday is a national holiday) and during year-end/new-year holidays.
Do not touch the tropical plants or tap on the aquarium glass.
