[note 1] Mount Izumi Katsuragi is an 858 metres (2,815 ft) mountain located on the Kongō Range, straddling the prefectural boundary between Osaka and Wakayama in Japan.

[1][2] Parts of the mountain lie in Kishiwada and Kaizuka, Osaka, as well as in Kinokawa, Wakayama.

The north slope of Mount Izumi Katsuragi is covered in a wood of Japanese beech, which favor growing at elevations high enough to remain fairly cool.

Harvesting the trees in this wood is forbidden by the association of Hachidairyūō shrines and temples, and this is the southernmost stand of Japanese beech on Honshū.

[4] Mount Izumi Katsuragi is easily accessible by car from three different directions, with all three roads meeting near the summit.
