Optimal PPP/PFI Method Selection by Municipality Size — From Under 50,000 to Designated Cities
The optimal PPP/PFI method varies by municipality population, fiscal capacity, and organizational resources. This article presents a framework for realistic method selection across five population tiers — from municipalities under 50,000 to designated cities — analyzing success requirements and considerations for each stage.
TL;DR
- For small municipalities under 50,000, the Designated Manager System, proposal-based selection, and small concessions are realistic options — PFI Act application often fails the cost-benefit test
- Medium municipalities of 50,000–200,000 represent the optimal zone for Park-PFI and small concessions, with potential for staged progression toward PFI Act projects
- Designated and core cities of 200,000+ can access the full spectrum of methods including concessions, but internal promotion structures and specialist staffing determine success

PPP/PFI methods are diverse, and no single method suits all municipalities. Three key variables influence method selection:
- Market environment (private operator interest): Larger cities attract more operator interest and support competitive procurement. Small municipalities face a realistic risk of "zero applicants"
- Internal capacity (know-how and staffing): Smaller municipalities report significantly higher rates of "insufficient understanding, know-how, and staffing" as barriers
- Facility scale and project cost: PFI Act projects typically require project costs of ¥1 billion or more, making them overbuilt for small facilities
The Cabinet Office published a guide for small and medium municipalities in October 2024, formally recognizing the importance of size-appropriate method selection.
Small Municipalities Under 50,000
Staged approach using Designated Manager, proposal-based selection, and small concessions
Realistic Method Options
| Method | Fit | Rationale |
|---|---|---|
| Designated Manager System | Excellent | Extensive implementation track record, low institutional barriers |
| Proposal-based selection | Excellent | Widely used for abandoned school reuse; flexible condition design |
| Small Concession | Good | Suited for idle public property under ¥1 billion |
| Park-PFI | Fair | Cases exist in municipalities of 20,000, but revenue viability is challenging |
| PFI Act | Poor | Project and procedural costs yield unfavorable cost-benefit ratios |
Recommended Staged Approach
For small municipalities, a staged approach rather than jumping directly to the PFI Act is effective:
Step 1: Adopt/improve the Designated Manager System for existing facilities (build internal know-how) Step 2: Utilize idle facilities through proposal-based selection (gain collaboration experience) Step 3: Progress to small concessions or Park-PFI (gain operating rights and revenue experience)
Success Requirements for Small Municipalities
- Leverage wide-area collaboration: Conduct joint sounding surveys with neighboring municipalities to secure private operator access
- Utilize external support: Leverage regional block platform training and the Cabinet Office's PPP/PFI expert dispatch program
- Mayoral leadership: In small municipalities, the mayor's decision-making directly determines project momentum
Medium Municipalities: 50,000–200,000
Optimal Zone Methods
Medium municipalities occupy the zone where PPP/PFI method options are widest.
| Method | Fit | Rationale |
|---|---|---|
| Designated Manager System | Excellent | Continues as the fundamental baseline method |
| Park-PFI | Excellent | Optimal zone: Park scale and visitor numbers support revenue facility viability |
| Small Concession | Excellent | Ideal for idle public property utilization |
| PFI Act (BTO) | Good | Feasible for facilities with project costs exceeding ¥1 billion |
| Concession | Fair | Facility scale constraints limit applicable cases |
Park-PFI and Small Concession Strategies
Three success factors for Park-PFI in medium municipalities:
- Location: Sites with steady daily visitor flow (adjacent residential areas, station proximity)
- Sounding survey execution: Pre-verify private operator interest and project condition feasibility
- Coexistence with surrounding commerce: Ensure park revenue facilities do not undermine nearby existing businesses
Small concessions were defined as targeting idle public property with project scales under approximately ¥1 billion in November 2023. They are well-suited for former municipal offices, health centers, and kindergartens held by medium municipalities.
Priority Review Procedure Response
The Priority Review Procedure threshold has been lowered to population 50,000+. For municipalities in the 50,000–100,000 range, formulating the procedure itself becomes a new task. Referring to the Cabinet Office formulation guide and embedding it into internal project evaluation processes is essential.
Large Municipalities: 200,000+
Full-Spectrum Method Selection
Core cities and designated cities with populations of 200,000+ can access all PPP/PFI methods.
| Method | Fit | Representative Facilities |
|---|---|---|
| Designated Manager System | Excellent | Gymnasiums, cultural halls, community centers |
| Park-PFI | Excellent | Urban parks broadly |
| Small Concession | Excellent | Former municipal offices, idle public land |
| PFI Act (BTO/BOT) | Excellent | Schools, government buildings, hospitals, waste treatment |
| Concession | Excellent | Airports, waterworks, sewerage, stadiums |
Internal Promotion Structure Design
In large municipalities, while method options expand, internal promotion structures determine success. Fukuoka City, after experiencing the Thalasso Fukuoka PFI project failure, established a city-wide "Optimal Project Method Review Committee" in 2011 and developed clear public-private partnership criteria.
Method Selection Flowchart
Decision criteria by facility type, project scale, and regional characteristics
The following flowchart provides decision criteria for method selection based on facility characteristics:
Step 1: Assess project cost scale
- ¥1 billion+ → PFI Act consideration (proceed to Step 2)
- Under ¥1 billion → Small Concession / Park-PFI / Designated Manager (proceed to Step 3)
Step 2: Consider facility operation model
- User fee revenue expected → Consider concession or independent revenue PFI
- Administrative service delivery is primary → Consider service purchase PFI
Step 3: Identify facility type and location
- Urban park → Park-PFI
- Idle property (former offices, abandoned schools) → Small Concession / Proposal-based
- Existing facility management → Designated Manager System
Step 4: Verify market interest via sounding
- Multiple operators express interest → Proceed to selection method design
- No interest → Revise project conditions or continue direct management
