I'm afraid November may be a little late. The Shiga Kogen official tourism site (which covers Shibu Onsen) lists a number of hiking trails nearby, most notably the Ikemeguri (Pond Loop) Course, but the referenced Maeyama summer chair lift stops running for the season on October 29th. This doesn't mean you can't hike, but it does strongly imply that there will be zero facilities or public transport available and weather conditions are unlikely to be in your favor.
