Firefly viewing season is beginning earlier than usual in Kyushu due to the warmer weather, and fireflies have already been spotted in some areas. Fireflies, known as hotaru in Japanese, signal the start of summer, similar to the sakura season. Their presence moves northward from the south of Japan, similar to the cherry blossoms. Fukuoka Now has curated nine spots in the Fukuoka suburbs that are perfect for firefly viewing.
Firefly Viewing Season:
In Fukuoka, the best time to see fireflies is from late May to mid-June, from sunset until 9 pm. They have already made an appearance in other regions, so keep an eye on the firefly forecast for more information! Fireflies are typically found near clean water sources and green spaces. They emerge shortly after it rains, when the wind is low, the humidity is high, and the temperature is comfortably warm. Adult fireflies live for only one to two weeks, but during this brief period, their flickering lights create a captivating, enchanting night display.
Hotaru Viewing Tips:
When viewing fireflies, keep the following tips in mind:
1. Do not use flashlights or flash photography, as fireflies communicate via their light signals. They will fly in darkness if exposed to other light sources or camera flashes.
2. Do not take fireflies home. They thrive by clean rivers and live for only 7-10 days. It’s best to leave them in their natural environment.
3. Keep their habitat clean by not littering.
4. Check the weather before your visit. Fireflies do not emerge when it’s too cold, too windy, during heavy rain, or under intense moonlight.
5. Plan your visit. The optimal time to view fireflies is between 19:30 and 21:00.
6. Be quiet and respect the serenity of nature.
Popular Firefly Varieties in Kyushu:
1. Genji-botaru (Luciola cruciata) – The most recognized firefly species in Japan, found across Kyushu and Honshu. They spend their larval stage near clear streams.
2. Heike-botaru (Aquatica lateralis) – As common as the Genji-botaru in Japan, they are smaller and breed in rice paddies and marshes.
3. Hime-botaru (Luciola parvula) – Known for their intense brightness and characteristic blinking, this species is widespread in Japan. They usually inhabit forests and are therefore not commonly observed by humans.
