The other day, a firefly dropped in my house in accident. I hear they can survive only a week after they emerge. I slowly and patiently guided it to outside.
From around July 20th, an outdoor activity to watch out fireflies will be held here in Hakuba. They guide you to Lake Aoki, you have to roar a Canadian canoe for 12 passengers at the most. 3,500 yen per person for adults, 3,000 yen for elementary school children. Kindergarteners and youngers are not qualified for this event. Old local people here in Hakuba tells there used to be a lot of fireflies in Hakuba. It seemed they were decreasing but lately people protect them so they show up again in summer which is nice!
