U.S. Marine Corps Air Station Iwakuni and Rental Demand
Base-Related Demand Structure
U.S. Marine Corps aviation units are stationed at Marine Corps Air Station Iwakuni, with approximately 10,000 military personnel, civilian employees, and their families living in the area. Since on-base housing cannot accommodate everyone, a considerable number reside in private rental housing off-base.
| Demand Segment | Estimated Rental Demand | Rent Level | Contract Features | |--------|-----------|---------|-----------| | U.S. Military Officers | Approx. 200-400 households | ¥120,000-200,000/month | Paid through OHA (Overseas Housing Allowance) | | U.S. Military NCOs | Approx. 300-500 households | ¥80,000-140,000/month | Paid through OHA (Overseas Housing Allowance) | | Civilian Employees | Approx. 100-200 households | ¥80,000-150,000/month | Corporate contracts | | Base Employees (Japanese) | Approx. 500-800 households | ¥40,000-80,000/month | Individual contracts | | Contractor Employees | Approx. 300-500 households | ¥35,000-60,000/month | Individual/Corporate contracts |
Characteristics of U.S. Military Rental Properties
Rentals to U.S. military personnel offer the attraction of stable rent payments through housing allowance (OHA) and the possibility of setting rents higher than market rates. However, attention must be paid to regular move-ins and move-outs due to 2-3 year rotation cycles, English communication requirements, and certain standards required for property specifications (safety standards, size, etc.).
