Several buildings, such as the former ship agency, showcase unique construction techniques intended to prevent fire spread in dense wooden environments.

The Townscape of Mitarai is a historic preservation district located on Osakishimojima Island in the Seto Inland Sea. It flourished during the Edo period as a vital port of call for Kitamaebune merchant ships waiting for favorable winds and tides. The district retains its authentic architectural heritage, featuring traditional machiya townhouses, merchant residences, and tea houses that line narrow, winding streets. Many structures are built on stone embankments extending into the sea to accommodate the tidal shifts. The area is designated as an Important Preservation District for Groups of Traditional Buildings by the Japanese government. Visitors can explore preserved interiors, including former clinics, banks, and communal meeting halls that document the island's economic history. Unlike many other heritage sites, Mitarai maintains an active residential community, blending modern life with Edo-era spatial planning.
