Selecting PPP Methods by Fiscal Capacity Index — Optimal Solutions Across Five Tiers from 0.3 to Beyond 1.0

The Fiscal Capacity Index is the 3-year average of standard fiscal revenue divided by standard fiscal demand, serving as the fundamental measure of a local government's financial strength. Municipalities scoring 1.0 or above are classified as non-grant recipients (not receiving Local Allocation Tax), while those below 1.0 are grant recipients.

This indicator shapes PPP/PFI method selection for three clear reasons:

1. Bond issuance capacity: Municipalities with higher fiscal capacity have greater borrowing headroom, making the "conventional public works" benchmark in VFM (Value for Money) calculations a viable baseline
2. Discretionary revenue margin: Even small-scale PPP methods like small concessions require general revenue expenditures for sounding surveys, feasibility studies, and bid documentation. The Cabinet Office published a utilization guide for small and medium municipalities in October 2024, but securing even study budgets is challenging for many
3. Private sector appetite: Low fiscal capacity generally correlates with small populations, limiting market attractiveness for private operators

The FY2023 national average for municipalities was 0.49, meaning more than half depend on Local Allocation Tax transfers. Acknowledging this reality and selecting methods that match fiscal capacity is the first step toward successful PPP/PFI implementation.

The following five tiers were designed by cross-referencing fiscal capacity indices with actual PPP/PFI adoption cases. Tier boundaries are not absolute and may shift based on individual circumstances (population trends, location, industrial structure).

Facing Reality

Municipalities with a Fiscal Capacity Index below 0.3 include many of the 885 designated depopulated municipalities nationwide. With over 70% of standard fiscal demand covered by Local Allocation Tax, even budgeting for PPP/PFI feasibility studies is challenging.

Viable Methods

Methods to Avoid

PFI Act projects and concession methods are unrealistic at this tier. The conventional public works baseline for VFM calculations is itself infeasible, and private operator interest cannot be expected.

The Breakthrough

Depopulation Countermeasure Bonds — with 100% appropriation rate and 70% Local Allocation Tax coverage — are the breakthrough for this tier. The mindset shift from "build new through PPP" to "consolidate facilities before PPP" represents the realistic first step for municipalities below 0.3.

Small Concession as the Optimal Zone

Municipalities with a Fiscal Capacity Index of 0.3–0.5 are the prime target for small concessions. They hold idle public real estate while being too small for PFI Act application — sitting precisely in the "institutional gap."

Manazuru Town Case — Fiscal Capacity Index 0.48

Manazuru Town (Kanagawa Prefecture, population approximately 6,200) is pursuing a small concession with a population of just 6,200.

The former Folk Museum (former Tsuchiya Residence) is a historic Meiji-era building that faced rising maintenance costs. After closing in September 2024, the town received approval under MLIT's Small Concession Formation Promotion Program and is preparing operator solicitation in partnership with ENJOYWORKS.

Three lessons emerge:

1. Leveraging national support: Small municipalities unable to self-fund studies should actively utilize MLIT accompaniment support
2. Asset inventory: Identifying resources with private sector appeal (such as historic buildings) is the starting point
3. Staged approach: Build one small concession track record before considering PFI

Shimoda City Case — Fiscal Capacity Index 0.46

Shimoda City's Fiscal Capacity Index is 0.46 (FY2024 3-year average). The notable case here is the conversion of the former Inaozawa Junior High School into the new city hall.

The former city hall was located in a tsunami inundation zone. After the 2011 Great East Japan Earthquake accelerated relocation planning, fiscal constraints led to a 2021 pivot: the soon-to-close Inaozawa Junior High School was seismically assessed, confirmed structurally sound, and renovated into municipal offices. Partial operations began on April 30, 2024.

While not a PPP/PFI project per se, this exemplifies how a municipality with 0.46 fiscal capacity solved its challenge through "existing stock utilization rather than new construction" — offering direct lessons for PPP method selection in similarly positioned municipalities.

The Optimal Zone for Park-PFI and DBO

Municipalities with a Fiscal Capacity Index of 0.5–0.7 typically have populations of 50,000–100,000. Park-PFI and DBO (Design-Build-Operate) deliver the strongest cost-benefit outcomes in this tier.

Staged Approach Design

The recommended progression for Tier 3 municipalities:

Step 1: Implement Park-PFI on one urban park (integrated revenue facility + designated park facility development) Step 2: Build internal PPP/PFI know-how based on Park-PFI experience Step 3: Evaluate DBO or PFI Act applicability when updating the Public Facility Comprehensive Management Plan

Priority Review Procedures

The FY2024 Action Plan revision lowered the Priority Review Procedure threshold to municipalities of 50,000+. Most Tier 3 municipalities fall within this scope, making it logical to develop method selection criteria alongside procedure formulation.

Full-Scale PFI Act Operation

Municipalities with a Fiscal Capacity Index of 0.7–1.0 are concentrated among core and special cities. Full PFI Act BTO/BOT methods become viable at this tier.

Organizational Requirements

Minimum organizational infrastructure for PFI Act projects:

1. Specialist department or dedicated staff: Personnel handling PPP/PFI project planning, solicitation, contracting, and monitoring end-to-end
2. External advisory engagement: Expert advice across legal, financial, and technical domains
3. Cross-departmental review committee: Coordination among facility-managing departments, finance, legal affairs, and planning divisions

Complex Facility PPP

At this tier, complex facility PPP — consolidating libraries, childcare centers, and community halls into a single building procured under the PFI Act — delivers both scale economies and user convenience.

---

Full-Spectrum Concession and Wide-Area PFI

Non-grant municipalities with indices above 1.0 are concentrated in major metropolitan areas (parts of Tokyo's 23 wards, Nagoya, Kawasaki, etc.). The full PPP/PFI toolkit including concessions is available.

Tier-Specific Challenge

Paradoxically, fiscal surplus creates the biggest barrier: "We can do it the traditional way" inertia. Ensuring VFM evaluation objectivity and demonstrating "the value of private sector expertise" with concrete numbers to councils and residents is essential.

"Institutional barriers" in public asset revitalization are real. But their height varies dramatically with fiscal capacity. Recommending PFI Act projects to a municipality with a 0.3 index is like recommending Everest to a beginning hiker.

What matters is accurately assessing the current position and climbing one step at a time. Just as Manazuru Town started with a single small concession and Shimoda City chose existing stock utilization over new construction, right-sized method selection matched to fiscal reality is the starting point for sustainable public-private partnerships.
