Flow of the course
About this spot
A park located about a 5-minute walk from the Onogawa Onsen hot spring town. It is a famous firefly-viewing spot, introduced on Yonezawa City's official website, where Genji fireflies, Heike fireflies, and Hime fireflies can all be seen at the same time.
Tips
There is a free parking lot (about 20 spaces) run by the Onogawa Ryokan Association. Fireflies are typically visible only from mid-June to mid-July; at other times of year, the park is just for a stroll.
