Mount Ishizuchi (石鎚山, Ishizuchi-san) is a 1,982-metre-high (6,503 ft) mountain on the border of Saijō and Kumakōgen, in Ehime, Japan.

It is known as 'the roof of Shikoku' and the sharp, rocky summit resembles a huge stone hammer (石鎚, ishizuchi).

Mount Ishizuchi is an important object of worship in this region and one of the major centers of Shugendō, a sect of mixture of Shinto and Buddhism.

However, it is possible to hike all the way to the peak along a trail which includes stairs and ramps with handrails.
