Hotaruan is a rare heritage property in Miyama, currently operating as an accommodation facility, originally constructed over 150 years ago and officially designated as a National Tangible Cultural Property.
Situated on approximately 5,000m² of land, the residence retains its traditional thatched roof, irori hearth, and timber structure while incorporating modern amenities such as a cypress bath, sauna, and fully equipped kitchen. The layout provides two Western-style bedrooms, a Japanese tatami room, and updated facilities to support both residential and accommodation use.
With its historic designation, architectural authenticity, and expansive setting, Hotaruan represents a distinctive opportunity for cultural preservation combined with income-generating potential in Japan’s growing heritage tourism sector.
