The houses are preserved exactly as they were left after the debris flow, with some structures still showing ash layers up to the roofline.
The site commemorates the 'Heisei' eruption, which significantly altered the local geography of the Shimabara Peninsula.
These specific houses were part of a residential area in the Fukae district that was designated as a restricted zone during the period of peak volcanic activity.
The preservation process involved structural reinforcement of the homes to allow them to withstand weathering while maintaining their post-disaster appearance.
The Buried Houses of Mt. Unzen Eruption Preservation Park serves as an outdoor museum featuring homes partially buried by pyroclastic flows during the 1990-1995 volcanic activity of Mount Unzen. The site preserves three original residential structures encased in hardened volcanic ash, providing a direct visual record of the disaster's scale. Visitors walk through the protected park area to view these ruins, which remain in their original positions relative to the eruption site. The park was established to document the geological impact on local civilian infrastructure and serves as a center for disaster education. Informational signage throughout the site details the timeline of the 1991 major pyroclastic flow that reached this neighborhood.
