Ontake Mountains



This mountains are located at the border of Nagano and Gifu prefectures.  It is called “Kiso no Ontake-san”.  The eruption at 11:52 am, September 27th, 2014 is still clearly remembered by many of us.  It was an emotional tragedy where 63 people died or went missing.  As of 2019, restricted areas have become smaller and smaller.  However, there remains an entry restriction from Kyu-goume to O-taki-chojo, and Ken-gamine on the Tanohara course. Therefore, 1. A course that hikes to the summit of Ken-gamine by use of the Ontake Ropeway 2. A course from Nigorigo hot springs on the Gifu side 3. A course from Kaida plateau, will be introduced here.  When visiting Ontake Mountains by any routes, please pays your respects for those victims of the eruption.  The summit of Ken-gamine can be approached only from July 1st to the middle of October.  However, from Ohtaki guchi, hiking is permitted only up to the Ohtaki summit.
