The term "PPP/PFI" appears frequently in government documents and news coverage, yet the two concepts are often conflated. A clear definitional foundation is essential.
PPP (Public-Private Partnership)
PPP is the umbrella term for all arrangements in which private capital, expertise, or management capabilities are leveraged to deliver public services. It refers to the full spectrum of mechanisms by which governments partner with the private sector in the development, management, and operation of public facilities — encompassing approaches that have historically been handled entirely by government.
PPP includes many distinct methods: the Designated Manager System, PFI, concession arrangements, small concessions, Park-PFI, PPP leasing, and bundled management contracts — all are forms of PPP.
PFI (Private Finance Initiative)
PFI is the specific method within PPP that refers to leveraging private capital, management capability, and technical expertise to develop, maintain, and operate public facilities. It draws its legal basis from the PFI Act (the Act on Promotion of Private Finance Initiative, enacted in 1999).
The relationship between PPP and PFI in a single line:
PFI ⊂ PPP (PFI is contained within PPP)
When the term "PFI" is used precisely, it refers to projects conducted under the PFI Act. Arrangements that leverage private sector participation without invoking the PFI Act — such as the Designated Manager System or Park-PFI — are properly described as PPP, not PFI.
A Map of Seven Representative PPP/PFI Methods
The following table presents the landscape of representative methods organized by the Cabinet Office.
| Method | Summary | Primary Facility Types | Legal Basis |
|---|---|---|---|
| Designated Manager System | Delegates management of public facilities to private entities | Sports facilities, cultural facilities | Local Autonomy Act, Art. 244-2 |
| PFI Act (BTO/BOT/BOO/RO) | Private capital funds facility development and operations | Large facilities: offices, hospitals, schools | PFI Act |
| Concession | Municipality retains ownership; transfers operating rights to private entity | Airports, toll roads, water utilities | PFI Act, Art. 2(6) |
| Small Concession | Operating rights for small-scale public facilities | Local community facilities | Regional Revitalization Act, etc. |
| Park-PFI | Private revenue-generating facilities within urban parks | Urban parks | Urban Parks Act, Art. 5-2 et seq. |
| Bundled Management Contract | Single-package outsourcing of multi-facility maintenance | Roads, parks, facility clusters | Local Autonomy Act |
| PPP Lease | Municipality leases private facility for public use | Offices, service counters | Local Autonomy Act |
Overview of the PFI Act and Value for Money
The 1999 PFI Act's purpose, project structure, and how Value for Money is calculated
The PFI Act: Background and Basic Structure
The PFI Act was enacted in 1999 (Heisei 11). Its stated purpose is "to develop, maintain, and manage public facilities efficiently and effectively by leveraging private capital, management capabilities, and technical expertise."
The basic structure of a PFI project:
- Implementation policy formulation and publication: The municipality publishes project objectives, conditions, and risk allocation
- Private operator recruitment and selection: The best proposal is selected from competing submissions
- SPC (Special Purpose Company) establishment: Not required by the PFI Act; set by the terms of the solicitation
- Facility development, maintenance, and operation: The private sector manages this as an integrated package (the Cabinet Office guide puts earlier project terms at roughly 7 to 30 years)
- Transfer at contract expiration: The facility is returned to public ownership (in BTO/BOT structures)
PFI Project Types
| Type | Description |
|---|---|
| BTO (Build-Transfer-Operate) | Private sector builds → ownership transfers upon completion → private sector operates. Most common type. |
| BOT (Build-Operate-Transfer) | Private sector builds and owns → operates → transfers at contract end |
| BOO (Build-Own-Operate) | Private sector builds, owns, and operates indefinitely (no transfer) |
| RO (Rehabilitate-Operate) | Renovation of existing facility + operations (suitable for abandoned school reuse) |
What Is Value for Money (VFM)?
The key metric for evaluating whether to use PFI is Value for Money (VFM).
VFM = Cost under traditional public delivery (PSC) − Cost under PFI (LCC)
- PSC (Public Sector Comparator): Lifecycle cost if the government developed the facility using traditional methods
- LCC (Life-Cycle Cost): Total cost under PFI — construction, operations, maintenance, and decommissioning combined
A positive VFM (lower total cost under PFI) is the foundational condition for PFI adoption. From FY1999 to the end of FY2024, 1,154 PFI projects had published an implementation policy, 71 of them public facility operation projects. Cumulative contract value stood at 9,808.8 billion yen as of 31 March 2025. This is the sum of initial contract values for projects whose public cost share was fixed in each year; it excludes operating-right consideration and is a different measure from the project scale used in the Action Plan.
Cabinet Office Action Plan Overview
FY2022–2031 targets, Priority Review Procedures, and implementation status
The Action Plan's Project Volume Target
The Cabinet Office's Private Finance Initiative Promotion Council revises the Action Plan each year. The most recent is the 2026 revision, adopted on 11 June 2026.
Having met the 21 trillion yen target set for FY2013 to FY2022 within seven years, and taking into account results over the three years from FY2022 and wider economic conditions, the plan aims for 40 trillion yen in project volume over the ten years from FY2022 to FY2031. The targets by category are 3 trillion yen for Category I (public facility operation projects), 12 trillion yen for Category II (revenue-generating projects), 13 trillion yen for Category III (public real estate utilization), and 12 trillion yen for Category IV (other).Category I fell from 7 trillion yen in the earlier revision to 3 trillion yen. A footnote explains that the three years from FY2022 included no project on the scale of Kansai and Osaka International Airports, and none of that size is currently foreseen.
These targets reflect the dual pressures of ageing public infrastructure and fiscal constraint. Over the 30 years from FY2019 to FY2048, maintenance and renewal is projected at about ¥280 trillion under reactive maintenance and about ¥190 trillion under preventive maintenance. The scope is the twelve fields under MLIT (roads, rivers, sewerage, ports, parks, public housing, government buildings and others), not public facilities alone.
Priority Review Procedures
One of the most operationally significant components of the Action Plan is the Priority Review Procedure (優先的検討規程).
A Priority Review Procedure is a formal internal regulation requiring that, for any public facility project above a specified cost threshold, the municipality must first evaluate the feasibility of PPP/PFI before deciding to proceed with traditional public delivery.
The requirement to establish such procedures has already been extended to municipalities with populations of 200,000 or more, and is now being expanded to municipalities with populations of 20,000 or more.Applicable project thresholds (Cabinet Office guidelines):
- Building-type projects with a project cost of ¥1 billion or more
- Operations-type projects with a project cost of ¥100 million or more
The PPP/PFI Promotion Office
The PPP/PFI Promotion Office within the Cabinet Office is responsible for overall coordination and promotion. For local governments, it offers a range of support resources including expert dispatch programs, manuals, training, and subsidy programs.

Method Comparison Table
| Method | Typical Project Scale | SPC Required | Risk Transfer Level | Complexity | Approximate Case Count |
|---|---|---|---|---|---|
| Designated Manager System | Any size | No | Low | Low | Tens of thousands |
| Bundled Management Contract | ¥tens of millions+ | No | Low-Medium | Low-Medium | Many |
| Park-PFI | ¥tens of millions–¥billions | No | Medium | Medium | 203 parks |
| Small Concession | ¥tens of millions–¥billions | No | Medium | Medium | No published count |
| PFI Act (BTO, etc.) | No provision | Set by the solicitation | High | High | 1,154 |
| Concession | ¥10 billion+ | Generally yes | High | High | Dozens |
| PPP Lease | Any size | No | Low | Low | Many |
Recommended Evaluation Sequence
A staged approach is most practical for municipalities:
STEP 1 — Begin by reviewing the Designated Manager System
When revisiting the management approach for an existing facility, first evaluate whether the current designated management structure can be refined. Strengthening the relationship with existing designated managers, reviewing management fees, and improving performance evaluation systems are relatively low-barrier starting points.
STEP 2 — Conduct a sounding survey to confirm market interest
Before adopting a new method, conduct a sounding survey to gauge private sector interest and feasibility. Sounding is low-cost and represents the lowest-barrier tool for gathering information about PPP/PFI options.
STEP 3 — Test Park-PFI or small concessions with parks, schools, or smaller facilities
Where urban parks exist, Park-PFI is a natural candidate. For abandoned schools or small community facilities, small concessions or proposal-based selection are practical options. These approaches are workable below ¥1 billion project scale and without SPC formation, and can produce results within a shorter timeframe.
STEP 4 — Evaluate the PFI Act for large-scale facility renewals
For large-scale renewals (project cost ¥1 billion or more) of facilities such as municipal offices, gymnasiums, or schools, undertake a formal VFM analysis and proposal process under the PFI Act. At this stage, the Cabinet Office expert dispatch program and survey cost subsidies become valuable resources.
Five Common Misconceptions
PFI ≠ privatization, SPC is not always required, PFI Act is rarely used for schools, etc.
Misconception 1: "PFI is privatization"
The reality: PFI does not transfer ownership of facilities or administrative responsibility to the private sector. The government remains the accountable party for public service delivery; PFI leverages private capital and expertise to improve efficiency. It is categorically distinct from privatization (民営化).
Misconception 2: "PFI always requires forming an SPC"
The reality: What the PFI Act says about corporate form is a single disqualification: anyone that is not a corporation may not respond to a solicitation for an operator of a specified project. No provision calls for a special purpose company (SPC). Whether an SPC is used is set by the terms of the solicitation. PPP methods that do not invoke the PFI Act, including Park-PFI, small concessions, and abandoned school proposals, carry no SPC provision either. Many entry points into public facility operations are available to small and mid-sized operators without forming an SPC.
Misconception 3: "The PFI Act cannot be applied to abandoned schools"
The reality: Application of the PFI Act to abandoned school reuse is technically possible but extremely rare. For projects below ¥1 billion in project cost — which describes most abandoned school cases — the PFI Act provides poor cost-benefit ratio. In practice, proposal-based selection, small concessions, and PPP leasing are the dominant methods for abandoned school reuse.
Misconception 4: "PPP/PFI is only relevant for large cities"
The reality: Park-PFI has been successfully implemented in municipalities with populations as small as 20,000. Small concessions and abandoned school proposals are well within reach for small municipalities. Priority Review Procedure requirements now extend to municipalities with populations of 20,000 or more, driving broader adoption at the local level.
Misconception 5: "Adopting PPP/PFI will automatically reduce administrative costs"
The reality: While positive VFM is the stated condition for PFI adoption, operator selection, contract management, and performance monitoring create new administrative costs. For municipalities undertaking their first PFI project, advisory and consulting fees can exceed initial estimates. When "adopting PPP/PFI" becomes an end in itself, the original objectives — cost reduction and service improvement — risk becoming secondary.

Getting Started
Three first steps you can take today
Three actions provide a practical starting point for municipalities approaching PPP/PFI:
- Read the Cabinet Office's "What is PPP/PFI?" page and introductory materials: The Cabinet Office's introductory page includes free PDF introductory texts that provide a systematic foundation in the framework
- Check and establish your municipality's Priority Review Procedure: If not yet established, refer to the Cabinet Office's guidelines and initiate the process promptly
- Inventory the renewal timelines, project costs, and key challenges for facilities under your responsibility: The viability of PPP/PFI varies significantly by facility. Producing a cross-departmental list of which facilities are realistic first candidates is the practical first step in building momentum
