~夏は夜。月のころはさらなり。やみもなほ、蛍の多く飛びちがひたる。また、ただ一つ二つなど、ほのかにうちひかりて行くもをかし。雨など降るもをかし。
枕の草紙 清少納言
・・・night is best in summer. Under the moonlight is beautiful. Fireflies fly in the darkness. Thus one here, two there, flying by give weak light. Rain gives the good mood.
the Pillow Book by Sei Shounagonn
As you may see in the old poem of Sei Shounagon, we Japanese love the faint light of fireflies.
Please feel our faint beauty here in Japan.
