Now several years after the eruption, is Mt. Ontake open for hiking?

Hi Nick,

It is possible to hike Mt. Ontake but it is still on level 2 alert for volcanic activity so an area approximately 1km wide around the summit is closed. Below is a link to a map (Japanese) of Ontake trails including trail closures.

Map of Mt. Ontake Trail Closures (Japanese)


  • The trail from the Tanohara Tourism Center (田の原観光センター) is closed.
  • Trails to the peak are closed from Ishimuro Sanso junction (石室山荘) and Nino-ike junction (二ノ池, see also 二ノ池新館, 二ノ池本館).
  • The trail between Nyonindo (女人堂) and the San’no-ike evacuation shelter (三ノ池避難小屋) is partially closed.

Also see the Japan Meteorological Agency’s Volcanic Warnings page for up-to-date information regarding volcanic activity.

I hope that helps answer your question!

Hello, do you know the latest information about climbing to Mt. Ontake? Is Tanohara route open?

Hi there,

Since Mt. Ontake’s volcanic alert level has been lowered from level 2 to level 1 this August, the Tanohara route has been reopened up to the Ninth station’s emergency hut (九合目避難小屋). The other closures remain the same, and the peak is still off-limits. Refer to the map linked above for more information.

Thank you Blair! Some people say that only way is to go from ropeway, Tanohara is closed right now. Because all in Japanese, I can’t be sure.

I’m glad I could be of help. Have a safe hike!

Hi Blair,

I’m confused. So I want to confirm that. Is the route from Tanohara to 9th Station open, Can I reach to 9th Station from Tanohara?

I apologize for any confusion. The route from Tanohara to the 9th Station is open—but only during daylight hours between 7:00 and 16:00. Beyond the 9th Station, the path remains closed. Here’s an updated map of the trail restrictions:

Mt. Ontake Trail Closures (September 2017)

It appears another trail section has closed due to a collapse of some kind (the red section on the bottom-right). It shouldn’t affect your trip.

Sorry to piggyback this a year later, but when might the summit become accessible again? I realize this is probably completely dependent on any volcanic activity, but if the mountain was completely calm for the next year, could it theoretically be possible for it to be re-opened, say, next year?

Hi there,

A path to the top of Kengamine, the highest peak of Mt. Ontake at 3,067m, will actually be opening beginning noon tomorrow, Tuesday, September 26th.

The route to Kengamine will close on October 8th, 2018 and reopen next year for the summer season (probably from July 1st, 2019).

You can reach the peak of Kengamine using the Kurosawa, Kaida, Hiwada, Kurumijima or Kosaka trails. The peak cannot be accessed from the Otaki Trail. See the map below for more information:

For more information about activities around Kiso, as well as the Ontake Ropeway, see this recent blog post.

There is a group of us planning to visit Japan at the end of March 2019 and would like to hike Mount Ontake. Will hiking trails be open or under snow at this time of year? Is there still restriction in the area since the last eruption?
