Around 270,000 years ago, a burst of volcanic activity helped shape the area.[4]
Aso Shrine at Mount Aso in Kyushu is a Shinto shrine traditionally held to have been a center of worship before the accession of Emperor Jinmu. The shikinaisha shrine complex at Ichinomiya in what is today Kumamoto Prefecture was said to have been established in 281 BC.[5]
The original location of the shrine is uncertain because it was destroyed and rebuilt many times in or near the crater of Aso-san.
On December 4, 1934, this park was first established as Aso National Park.[6]
