Shiretokoiozan Volcano is a very singular volcano which expels a humongous amount of molten sulfur. At the last eruption in 1936, more than 116 thousand of melted sulfur was expelled at the northwestern mountain flank called “Crater I” and the sulfur flowed into the Kamuiwakka Creek. The area was developed as a sulfur mine and almost all the sulfur was collected. But still we can see some pieces of sulfur on the rock surface today.

In this tour I will guide you and explain:
①The genesis of Shiretokoiozan and Shiretoko Five Lakes
②The history of Shiretoko Sulfur Mine and the mine ruins
③Mechanism of the molten sulfur eruption
using hand-made dioramas, panels and experimental tools in the field while we observe the crater, sulfur and mine ruins.
