Mount Iō, Stratovolcano in Shiretoko Peninsula, Japan.
Mount Iō is a stratovolcano on the Shiretoko Peninsula composed of andesite rock with numerous volcanic vents scattered across its slopes. The terrain reveals its volcanic nature through various geological features visible throughout the landscape.
The volcano shaped the Shiretoko Peninsula's geography over extended periods through its geological activity. Its ongoing processes continue to influence the region's natural landscape today.
The mountain stands as a natural landmark between Shari and Rausu, deeply connected to how locals navigate and understand their surroundings. Climbing holds special meaning for the communities living near its base.
Visitors should bring sturdy footwear and weather-appropriate clothing, as conditions change significantly higher up the mountain. Starting early allows enough daylight for the entire route without rushing.
Bright yellow sulfur deposits cover parts of the surface, created by the mountain's ongoing volcanic activity. These mineral formations shift and change, making the landscape appear different with each visit.
