On the name of Mount Sen, there are two explanations. 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. The other explanation is because the mountain is a mountain for xian. In Japanese, xian (仙) is pronounced ‘sen’.

There are three major routes to the top of this mountain. Mitani route and Iwazashin route start from Kadokura Bus Stop of Shinki Bus. It takes about two and half hours. The other route, Ichinara route is from Tanji Bus Stop, it takes about three hours.
