Onioshidashi Park is one of Japan’s best geoparks. Walk thru an old lava pool as nature reclaims a volcanic hellscape.

Onioshidashi Park (鬼押出し園) is a huge lava field formed by the volcanic eruption of Mount Asama, Nagano in 1783. The volcanic park is one of Karuizawa’s most interesting places, and a true gem among Nagano’s many wonders.

The Onioshidashi Volcanic Park is best accessed by rental car or by bus. There are only about 6 buses per day though, so if arriving by bus, be sure to note the return times before doing anything else, to avoid a 1-2 hour wait…or worse.

The park is open 8 AM – 5 PM daily (last entry 4:30 PM).
Admissions is ¥650 for adults.
Parking is free.
