Firefly viewing is one of the delights of early summer. Enjoy the beautiful light emitted by Genji-botaru (Luciola cruciata) and Heike-botaru (Luciola lateralis), the most common firefly species in Japan.
Expo Park is a rare place where you can still appreciate the magical natural light emitted by Genji-botaru and Heike-botaru, Japanese fireflies.
Please note that firefly viewing will be cancelled in the event of rain.
