โจ Fireflies โ May to July
Firefly Viewing in Japan
Japan's magical hotaru season โ late May to mid-July
About Hotaru Viewing
Japan has two iconic firefly species: Genji-botaru (larger, found by clean mountain streams) and Heike-botaru (smaller, in rice paddies). Both light up rural Japan from late May to mid-July, with peak in early-to-mid June. Many spots are designated National Natural Monuments. Viewing is silent, magical, and uniquely Japanese.

โจ Firefly Viewing Tips
- โArrive 30 min before sunset to find a spot and let your eyes adjust to darkness
- โWear dark clothing โ fireflies are attracted to dim natural conditions
- โBring mosquito repellent โ fireflies love the same humid environments mosquitoes do
- โDo not use flash photography โ it harms the fireflies and ruins the view for others
- โDo not catch or touch fireflies โ many sites are protected nature reserves
