Fukuoka Firefly Watching Guide 2019

It’s the start of firefly viewing season in Kyushu, so we’ve rounded up some of the best local hotaru festivals! Fireflies (hotaru in Japanese) are a symbol of the start of summer in Japan. Like sakura season, hotaru season starts in the south of Japan and moves up the country.

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.

Firefly Festival Guide

Many firefly festivals are held to celebrate the fleeting appearance of the glowing, winged bugs. You can make a day of your trip and enjoy food and entertainment from the afternoon to evening. Here are some of the best spots to view fireflies this year.

JR Hakata City Firefly Viewing

See a hundred fireflies in the heart of Hakata! Observe fireflies that were hatched inside the biotope located in Tsubame no Mori Hiroba, a rooftop garden above JR Hakata Station. Browse the stalls of the night market too, open every Friday and Saturday throughout the firefly-viewing season. Be sure to try some of the dagashi (inexpensive Japanese sweets)! The fireflies are active between sunset and 8:30 pm, so why not drop by on your way home?

Toho-mura Hoshuyama Hotaru Festival

From late May to mid-June, you can enjoy glowing fireflies in the night sky of Hoshuyama. Due to the heavy rains that fell in northern Kyushu in 2017, the number of fireflies might be fewer but the festival is being held to encourage their return. There will be stage events with taiko drum performances and a brass band ensemble as well as a lucky draw for local products. Enjoy browsing the many festival stalls too. There’s a temporary parking area at JR Hoshuyama Station where there are free shuttle buses to the venue.
