Ōya Mine History Museum

Ōya Mine History Museum is an underground facility carved from a former mining site that operated for centuries in this coastal region. The space preserves the original cavern walls with visible marks from manual extraction techniques used by miners over generations.

Mining operations in this area began in early periods and shaped local life for centuries, with techniques evolving from simple hand-digging methods. The site was eventually abandoned as extraction became uneconomical, but the caverns have been preserved and opened to the public since 2005.

The museum displays mining tools and objects that show how closely local people were connected to extracting natural resources over many centuries. Visitors can see directly how central this work was to the community's survival and identity.

The underground space stays cool year-round, so bring a jacket or sweater even during warm months. The cavern walkways are well-lit and accessible, though sturdy footwear is recommended for the sometimes uneven stone surfaces.

The cavern walls feature natural salt crystal patterns that formed through water evaporation over countless years. These delicate formations create an unexpected natural artistry that contrasts with the harsh industrial history of the site.
