Fireflies can be seen in the Genko district on the west side of Hidakagawa Town. The fireflies can primarily be seen around the Hidaka River, as well as around small streams and irrigation channels in the district. The fireflies appear in most years from late May to around mid-June. The Genko district is famous for its abundance of fireflies, and it holds firefly watching events in late May in the evenings. During the events, visitors can also listen to traditional music performances played on the koto and shamisen.
