Onioshidashi Volcanic Park

Onioshidashi Volcanic Park

If you're into volcanoes, take a trip to the "expelled demons" of Mount Asama.

On the Romantic Road between Karuizawa and Kusatsu Onsen is Onioshidashi Park. The name literally translates as 'expelled demons' - a beautifully poetic description of this lunar landscape. After a huge eruption from Mount Asama in 1783 an enormous stream of magma solidified here creating the dusty rock-strewn lava you see today. At the centre of Onioshidashi is a Buddhist Shrine perched on the lava rocks, dedicated to the Goddess of Mercy Kannon.

Next door is the Asama Volcano Museum which explains the geography of volcanoes and houses exhibits on plant and animal life which thrives in the volcanic environment around Mount Asama. There's also a simulator where you can experience volcanic activity.
