This flat space of Mt. Esan is the crater created by the eruption of the volcano of 618 meters height. Automobiles including buses are available to the parking lot at the altitude of 300 meters.
When the active volcano erupted approximately eight thousand years ago, the lava dome was created followed by other eruptions five thousand, three thousand, two thousand an five hundred yeas ago and six hundred years ago.
The stairs to the peak of the lava dome of Mt. Esan was made of ferro-concrete. The gap of the temperature of the ground in summer and winter must be so tough for natural materials.
