Mount Sen (千ヶ峰, Sen-ga-mine) is a 1,005.2 m (3,298 ft)　mountain of Chūgoku Mountains, located on the border of Taka and Kamikawa, Hyōgo, Japan.

This mountain is an important center of Kasagatayama-Sengamine Prefectural Natural Park.

Mount Sen is a typical fault-block mountain in this area.

One is because it has thousands of peaks (in Japanese ‘sen’ means thousand), however judging from the shape of the mountain, this explanation can not be believed.

In Japanese, xian (仙) is pronounced ‘sen’.
