Hirai River Fireflies

15 to 20 minutes by bus from Musashi-Itsukaichi Station or by car from the Hinode Interchange. In most years, fireflies can be seen in the area of the Hirai River from mid-June through mid-July. Your chances of seeing the fireflies are particularly high in the Oguno-Mitsuzawa district and the Iwai district on the upper reaches of the river. The best time to come is during the peak firefly period from late June between 7 p.m. and 8 p.m. Most of the fireflies are Genji fireflies, but some Heike fireflies can also be seen flying around. Please do not attempt to capture the fireflies and instead simply appreciate their beauty while also taking care to only stay in safe areas near the river.
