An event to view the fireflies that inhabit the walking routes in Moriyama City and around the Moriyama Institute of Firefly's Woods. During the period of the event, the Moriyama Municipal Sports Park parking lot is opened to those coming to see the fireflies, and a “Firefly Eco Bus” (free) also operates between Moriyama Station and the firefly habitat. With such other features as live music and displays of handmade lanterns, you can enjoy an illusory space and fun events while casually strolling through the city.
