It is located at the southern end of the Northern Japan Alps.
Its first historic eruption occurred in 1979. A landslide in 1984 was not related to an eruption and produced a debris avalanche and lahar running down valleys south and east of the volcano.
On-take volcano is one of the holy mountains of Japan and the destination for religious pilgrimage since 1792.

JMA reports seismic activity remained low, but maintains alert level 3, as sudden phreatic explosions could occur again. Fri, 14 Nov 2014, 07:48 JMA reported that cloud cover often prevented visual observations of Ontakesan during 5-11 November; white plumes rose 200-300 m above the crater rim and drifted NE, E, and SE. ...moreThe Alert Level remained at 3 (on a scale of 1-5).

According to press articles, 7 people are still missing from the 27 Sep eruption, but search and rescue operations are being suspended until springtime because of the winterly conditions. The Alert Level remained at 3 (on a scale of 1-5).

The death toll from last week's sudden explosion has risen to 51 fatalities. Most of them were attributed to head trauma (killed by impact of ballistic projectiles in the summit region of the volcano). [ less] Wed, 1 Oct 2014, 15:21 The death toll from Saturday's powerful, and deadly explosion of the volcano has now climbed to 48, press reports. The eruption was a sudden, unexpected (and unpredictable) phreatic explosion, i.e. caused by sudden evaporation of overheated water in the hydrothermal system of the volcano. ...moreIt took more than 250 climbers on the mountain, a popular hiking destination, and a sacred place for Japan's religious worshipers, by surprise. It is unclear whether this eruption is or not a precursor of a possible magmatic eruption in a near to medium future, i.e. caused by fresh magma coming to the surface. While search and rescue operations continue at high intensity, Japan's monitoring scientists are keeping an eye on possible changes that could indicate such a development. On the other hand, it is entirely possible, that the explosion remains a single event with no magmatic eruption following.
