By chance I learned that there are fireflies a moderate walk from where I live.
The neighborhood near the river has a group that takes care to preserve the river environment where the fireflies are found. They have fenced the area off but allow visitors to view the fireflies from a safe distance in the early summer.
These are 姫蛍 - Hime hotaru, Luciola parvula, a species of flashing fireflies found in Japan and parts of eastern Asia.
