Mount Ontake (御嶽山 Ontake-san?), also referred to as Kiso Ontake-san (木曽御嶽山?) is the second highest volcano in Japan at 3,067 metres, located around 100 km north-east of Nagoya. It is on the borders of Kiso and Ōtaki in Nagano Prefecture, and Gero in Gifu Prefecture. It should not be confused with Mount Mitake, a mountain in Tokyo written with the same characters, and various other Japanese mountains which share the name Ontake.
Thought to be inactive until 1979, it underwent a series of eruptions, but has not erupted since 1980.
The volcano has five crater lakes, Ni no Ike (二ノ池?) at 2,905 m being the highest mountain lake in Japan.
A small pond located near the base of Mount Ontake contains a number of Koi fishes that have achieved seemingly impossible life spans. The oldest known vertebrate animal known to recorded history was a koi fish named "Hanako," who died here in 1977, at the age of 226 years - outlasting the world's oldest tortoise by 38 years.
