The butterfly house maintains a constant temperature of approximately 25 degrees Celsius to sustain tropical butterfly species.
The facility is home to the Large Tree Nymph butterfly, one of the largest butterfly species in Japan.
It was one of the first public facilities in Japan to focus exclusively on insect education and research.
The museum complex integrates with the surrounding Koyaike Park, which is a major wetland area for migrating birds.
The research collection includes thousands of preserved specimens used for scientific taxonomy and public education.
The Itami City Insectarium is a specialized natural history museum centered on the study and observation of insects. Its primary feature is a large, glass-enclosed butterfly house that maintains a tropical environment year-round. Visitors can observe approximately 1,000 butterflies representing over 10 species flying freely within this controlled climate. The museum grounds include Koyaike Park, which provides a natural habitat for diverse local insect species. Interactive exhibits focus on the life cycles of insects and their ecological importance in local environments. The facility functions as both an educational hub and a conservatory for regional biodiversity.

Wear bright clothing to increase the likelihood of butterflies landing on you inside the conservatory.
Bring a macro lens or a camera capable of close-up photography, as the insects are often stationary on tropical foliage.
Check the daily butterfly emergence schedule, which is often posted near the entrance, to time your visit for peak activity.
Do not wear strong perfumes or colognes, as these can disturb the insects inside the glasshouse.
Closed on Tuesdays; if Tuesday is a national holiday, it closes the following day.
Do not touch or attempt to handle the butterflies, as their wings are highly fragile; refrain from using flash photography inside the butterfly house.
