At the latest teamLab exhibit held at Ginza 456, you can step into an enchanted digital forest full of butterflies. The exhibition is interactive and you can download an app to 'catch' different specimens to study them before releasing them back into the wild. You can also reach out to and try to touch the butterflies, though they will quickly fly away from your hand. When you snap a picture of a butterfly through the app, it disappears from the forest and will remain on your phone until you have gotten enough information for your app's collection book.
While the exhibit is free, reservations are required so as to avoid overcrowding the venue. Up to eight participants are allowed per 45-minute slot from 10.30am daily (last admission 6.30pm). You can book a time slot via the event website.
