Two-story and single-story residential facilities for singles (15 units total) using the 'Box Unit Construction Method' completed in Ama Town, Shimane Prefecture

The 'Ama Town Hishiura District Facility Construction Project' in the Hishiura district of Ama Town, Shimane Prefecture—a scheme in which the Japan Offsite Construction Association (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Toshinari Nagasaka) participated—has completed the construction of residential facilities for singles (two row-house buildings, 15 units total). The project was successfully handed over on March 23, 2026.

This project utilized 'offsite construction,' where approximately 70% of the construction process was completed on the mainland before being transported to the island. This approach solved the issue of labor shortages on the remote island while providing high-quality living environments with a short construction period.

[Project Background] Severe housing and labor shortages on remote islands

In recent years, Ama Town has faced a chronic and worsening shortage of housing for single individuals due to an increase in people wishing to relocate to the island, making the development of residential facilities an urgent priority.

However, local construction firms were already overwhelmed with projects amidst a labor shortage, making it difficult to respond to the demand. Furthermore, securing accommodations for construction workers coming from outside the island was extremely challenging.

As a solution to these issues, a public proposal process was held to recruit contractors from both inside and outside the island, seeking a solution that would realize a 'short construction period,' 'rational construction methods,' and the 'development of high-quality residential facilities.'
