Is it possible to hike to Mount Ontake this Saturday?
Which trails are open?
It is possible to climb Mt. Ontake during winter, but the mountaintop is no longer accessible for this year. Please see this announcement about Mt. Ontake’s trails.
The areas marked in red are all inaccessible, as well as the route between Nyonindo hut and the Kengamine summit.
The most recommended route up the mountain is via the Kurosawa Trail which can be reached from the top of the Ontake Ropeway. The ropeway will close for the year on November 4th. (See details about the Ontake Ropeway here.)
Please be aware that snow may begin to accumulate on the mountain, so you should bring winter climbing gear such as crampons and picks with you if you choose to climb it.
I hope that helps answer your question.
