Osore-yama volcano is an active stratovolcano on the Shimokita Peninsula in northernmost Honshu, Japan.
It is known locally also as Yake-yama, or "Burning Mountain". Older residents reported that large fires and clouds were sometimes seen from the summit, but the only confirmed historic activity took place around 1787.
Earthquake swarms have been documented at Osore-yama during the second half of the 20th century, and magma bodies have been detected beneath the volcano.
Definition of a volcano: A volcano is the term for any place on the surface of the earth, where hot molten rock (magma) reaches the surface.
