Ōya Mine History Museum

The underground museum spreads across 300,000 cubic meters with walls reaching 30 meters below ground, demonstrating the scale of past mining operations.

The museum, which opened on April 1, 2005, preserves evidence of manual mining techniques through visible hand-digging marks on its walls.

The museum displays mining tools and artifacts that illustrate the connection between local communities and their natural resources throughout different periods.

The temperature inside the mine remains constant throughout the year, making it necessary for visitors to bring warm clothing regardless of the season.

The cavern walls feature salt crystal formations that create natural flower patterns due to water evaporation processes.
