Night Observation Exhibition Room | While you wait to view the exhibits, you can see what the observation exhibition room looks like at night.
A huge mosquito net is set up inside the dome, and around 500 Genji fireflies dance around, shining brightly. You can enjoy the view while walking around the dome.
Why not enjoy the fantastic light of the fireflies?
You can see over 500 fireflies dancing and glowing in the semi-outdoor dome.
