Mt. Ogura (御座山) is a 2,112m peak in Minamisaku District, Nagano Prefecture.
From the rocky summit, you can see nearly the entire Yatsugatake Range; the panorama extends to Oku-Chichibu and Mt. Asama, with the appeal of quiet, remote-area mountain walking. It is also known as a famous mountain for rhododendrons.
It is counted among the 200 Famous Japanese Mountains.
