Niikappu mud volcano

The Niikappu mud volcano features multiple pools where gases escape from underground, causing the continuous eruption of mineral-rich mud through surface fissures.

The geological formation received official recognition as a Prefectural Natural Monument on January 18, 1968, marking its importance in regional natural heritage.

The mud volcano serves as an educational resource for local schools, helping students understand the geological processes and natural phenomena of their region.

Visitors can observe the mud volcano's activity from designated viewing areas throughout the year, with informational signs explaining the geological processes.

The temperature variations and microbial compositions within the mud create specific conditions that support specialized organisms adapted to this environment.
