Walk through a landscape of hardened lava

This otherworldly landscape of black, craggy rocks was created from molten lava when Mt. Asama erupted in 1783. Local legend says the eruption was so powerful that it blocked out the sun for days.

Mt. Asama Magma Stone Park, or Onioshidashi Park, is a permanent reminder of the eruption's impact. At the center of the park is Asamayama Kannondo Temple, built in 1958 to remember those who died in the disaster. People pray here to ward off bad luck.

Walk among the rocks to see over 100 species of alpine plants that grow there and catch views of Mt. Asama, one of Japan's most active volcanoes.
