Last night we took a drive out to Korimachi in Fukushima to see a firefly festival. The festival itself was very tiny, but the there was hundreds of fireflies. It was very hard to take pictures or videos with my camera in total darkness, but I managed this decent one here.
I had to use a very fast film speed combined with keeping the shutter open for 15 seconds. What is cool is that a firefly flew right in front of my camera during the picture, producing that green streak.
In Sendai 
I saw your firefly comment on fb and immediately came here, hoping for a picture. Yay – I was not disappointed! 🙂
It was so hard to take a picture I almost gave up.
It must be exciting to see them in person ! :]
It was super cool. I had previously only seen two, and both on separate occasions. So seeing so many was great.
This is absolutely beautiful.
You must have been the lucky person to take this great photo!!
I am very proud of Eribon.
Thank you. But some of the credit goes to the fireflies
Absolutely great!!
I’ve seen only once and only one.
I didn’t know they flash green.
Some were white and some seemed green or yellow.
