Fireflies, called hotaru, have a special place in Japanese culture. They are associated with fallen soldiers and romantic passion. They can be seen in traditional paintings and mentioned in poetry. It's not surprising that almost every region of Japan has several firefly watching events called hotaru matsuri. Many urban parks breed and release fireflies for this special occasion. However, in rural Japan, there are still plenty of places where you can see fireflies in wild nature.
