GUNMA Tourist Guide of Gunma Prefecture

Mt. Asama Magma Stone Park

Lava formed this work of art when Mt. Asama-yama erupted in 1783. Its name comes from the impressions of the people of the time, who said it looked like a devil had turned violent in the crater and pushed out the rocks. Enjoy the impressive panoramic site created by mother nature.
