Fukuoka Firefly Watching Guide 2022

Since the weather has been warmer than usual fireflies are already appearing in some areas. It’s the start of firefly viewing season in Kyushu, so we’ve rounded up some of the best local hotaru viewing spots ! Fireflies (hotaru in Japanese) are a symbol of the start of summer in Japan.

Firefly Viewing Season
The best time to see them in Fukuoka is from late May to mid-June, from sunset to 9 pm. They’ve already emerged in other places, so check out the firefly forecast for more details! Fireflies are usually found near clean bodies of water and greenery. They appear just after the rain when there is low wind, high humidity and the temperature is nice and warm. The lifespan of an adult firefly is only one to two weeks. In that short time, their fluttering lights brighten the night sky, showing us their beautiful, magical world.

Hotaru Viewing Tips

Here are some basic tips to remember when looking for fireflies:
1. No flashlights or flash photography. Fireflies communicate with each other through their own light signals. If there is another source of light, or a camera flash, the fireflies cannot communicate, and will instead fly in darkness.
2. Do not bring fireflies back home. Fireflies only live by clean rivers, and have a short lifespan of just 7~10 days. Leave them in their natural habitat.
3. Do not litter. Keep their habitat nice and clean.
4. Check the weather in advance. Fireflies don’t come out when it’s too cold, too windy, during heavy rain, or under strong moonlight.
5. Time your visit. The prime viewing time for fireflies is around 20:30~21:30.
6. Be quiet. Enjoy the peaceful atmosphere created by nature.

Popular Varieties of Fireflies in Kyushu

Genji-botaru (Luciola cruciata)
These are the best-known fireflies in Japan. They can be found all around Kyushu and in Honshu and spends time near clear streams during their larval stage.

Heike-botaru (Aquatica lateralis)
The Heike-botaru is as common as the Genji-botaru in Japan, but is smaller and breeds in rice paddies and marshes.

Hime-botaru (Luciola parvula)
This is one of the most common species across Japan and known for its intense luminance and characterized by its blinking. They are often found in forests, and so they are not as commonly seen by humans.
