Went there in May 2018 and the park looks almost abandoned. So, we had the whole park to ourselves. The view was breathtaking and the rock formations very interesting. It is some ways out from the main city attractions so we took a taxi to...More

Worth a detour. The view of Mt. Asama over the rugged lava formations is nice. After a 15 minutes walk from the parking place through the lava fields we arrived at a nice temple with an overview of the area.

The view on our drive to the location was amazing from Karuizawa. Mount Asama covered in snow was in sight at the last 5km. The formation of lava rocks were simply amazing.

The austerity of this place was humbling and beautiful. Worth a trip if you are at all interested in volcanology and the fleeting nature of life.

Spectacular views of mt Asama and the mountains of Nagano. Nice short walks through the lava rocks, kids got excited, and scenic views of Japanese temples and shrines along the way. It gets crowded during the Japanese holidays (beginning of August), so try to avoid.

I am not sure how to get to this place as we had a driver with us for that day. Anyway, I thought it was a really lovely place to just walk around at your own pace and enjoy the scenery. Located on higher grounds,...More

The park was filled with large stones hardened from lava. It would be a nice walk on a fine day with some lovely views of the surrounding mountains. Other than that, I wasn't sure what the appeal of the place was.
