Hotaru-iwa (Firefly Rock)

Hotaru-iwa (Firefly Rock) is a large natural rock located along the mountain trail of Mount Kurama, between Kurama-dera Temple and the surrounding forest paths. Hidden among ancient cedar trees, it is one of the many scenic landmarks that contribute to the mountain’s peaceful and spiritual atmosphere.

The rock is traditionally said to have been named after the many fireflies that once gathered nearby during early summer. Although it is a modest landmark, it provides visitors with a quiet place to pause and appreciate the natural beauty of Mount Kurama.

History

Hotaru-iwa, or Firefly Rock, has long been known as one of the most famous places to view fireflies along the Kibune River. According to local tradition, the Heian-period poet Izumi Shikibu visited nearby Kifune Shrine and composed poems inspired by the glowing fireflies in this area.

Even today, large numbers of fireflies can be seen around mid-June, preserving the natural beauty that has inspired visitors for more than a thousand years. Located along the walking route between Kurama-dera Temple and Kifune Shrine, Hotaru-iwa remains a peaceful stop where visitors can enjoy the harmony of forest, stream, and seasonal wildlife.
