Photo：gomafringo on flickrThe average temperature inside the cave is around 3 degrees celsius, which is enough to keep the cave covered with ice all year long.
The highlights of the Narusawa Ice Cave are the ice pillars formed by the water dropping from the ceiling.

The cave was formed by flows of lava from a massive volcanic eruption 1130 years ago.
