Mount Misen (弥仙山, Misen-zan) is a mountain in Oyogi-cho (於与岐町), Ayabe, Kyoto Prefecture, Japan that is considered to be sacred by the Oomoto religion.

[2][3] Osei Jinja (於成神社) on Mount Misen is where the religion's founder, Nao Deguchi, secluded herself in 1901 and received divine revelations (as described in Chapter 10 of Volume 38 in the Reikai Monogatari[4]).

Nao Deguchi would perform daily ablutions at a waterfall (大本開祖修業の滝) nearby.

[5][6] Kinpū Jinja (金峰神社) is located on the summit of the mountain, and Mikumari Jinja (水分神社) is at the foot of the mountain.
