Mount Mikuni (Gifu)

[1] A four-story observation deck, a prefectural park and camp grounds are located on top of the mountain.

[1] There are no other tall mountains nearby, so many visitors come to the park at night because the observation deck offers a good view of the surrounding Nōbi Plain.

The Aichi Prefecture side of the mountain is home to Nagoya Kōchin (名古屋コーチン), a regional breed of chicken.

During the Miocene Epoch, the mountain was an active volcano and caused the "turtle shell stones" (亀甲岩 kikkōiwa), which are a natural treasure of the village of Neba.
