This note introduces the hypotheses and scope of the Public Asset Utilization Research Lab (ISVD-LAB-005). It states which questions the lab seeks to answer and which methodology it uses.
What This Lab Examines
Japan's public assets (public facilities, public land, infrastructure) are entering a structural transition under the combined pressure of maintenance burden and population decline. According to MLIT, infrastructure maintenance and renewal costs are projected to reach approximately ¥190 trillion over the next 30 years. Meanwhile, of 7,612 closed schools nationwide, 1,951 remain unused.
The government's PPP/PFI Action Plan (FY2025 revision) sets a ¥30 trillion project target over FY2022 to FY2031 and positions public real estate utilization as a core policy. Schemes have proliferated: small concessions (platform established December 2024), Park-PFI, PFS (Pay for Success), and the personnel dispatch type of corporate hometown tax.
This lab reads the operational reality of these schemes structurally. Why do "institutions exist but do not move" and "cases succeed but do not scale" persist? The lab analyzes structural factors by cross-referencing public data from the Cabinet Office, MIC, MLIT, and MEXT with case material from across Japan.
Core Hypotheses
The lab departs from three hypotheses.
Hypothesis 1: Institutional existence and operational function do not co-vary. The adoption rate of priority review regulations reached 82.1% for municipalities with population over 200,000, but the operational rate stays at 70.5%. PFS has guidelines, grants, and expert dispatch in place, yet only 154 of 1,700 municipalities (about 9%) have implemented it. Adoption rates obscure the execution gap.
Hypothesis 2: The wall is more about knowledge and personnel distribution than money. The "10-year rule" simplifies subsidy return for facilities more than 10 years past completion. Zero-burden small concession models (Fukuchiyama type) exist. The reason things still do not move is that municipalities do not accumulate know-how for project design, sounding operations, and operator selection. According to MIC research, the top barriers to PPP/PFI adoption are "lack of know-how/knowledge" (36 cases) and "personnel shortage" (33 cases), with consultant dependency fixed as the dominant coping mechanism for small municipalities.
Hypothesis 3: The next axis of debate is the reversal of design sequence from "facilities" to "service outcomes." Public facility comprehensive management plan adoption rate reached 100%, but only 936 municipalities (54.3%) set numerical targets for facility reduction. What residents need is not facilities themselves but service outcomes: access to knowledge, health, mobility, and interaction. The 611 municipalities with electronic library services and 17.13 million convenience-store-based certificate issuances illustrate that pathways providing services without facilities are already operational.
Analytical Scope
The lab covers the following scheme types and issues.
| Scheme | Jurisdiction | Scope |
|---|---|---|
| PPP/PFI (including priority review regulations) | Cabinet Office | Adoption vs operation gap; population-size bias |
| Small concession | MLIT | Three walls (image, partner, project formation) and structure of breakthrough cases |
| Park-PFI | MLIT | Park-located revenue structures and local conditions |
| PFS (Pay for Success) | Cabinet Office | WTP estimation, logic model, internal consensus barriers |
| Corporate hometown tax (incl. personnel dispatch type) | Cabinet Office | As a funding and human capital pathway for public asset regeneration |
| Closed school utilization | MEXT | 10-year rule, urbanization control zones, subsidy patterns |
| Public service "softification" | Cross-cutting | Reversed design sequence and three risks |
Geographically the lab covers all of Japan, with focused attention on municipalities under 50,000-100,000 population (roughly 81% of the 1,788 total), whose structural disadvantage is severe.
Methodology
Source Priority
- Primary: public statistics, guidelines, fact-finding surveys from the Cabinet Office, MIC, MLIT, and MEXT
- Secondary: research and practitioner analyses from the Toyo University PPP Research Center, the Japan Economic Research Institute, PMC (Public Management Consulting), and similar bodies
- Case studies: PMC seminar records (e.g., April 14, 2026 session with 15 cases over 24 slides) and the latest tender/award cases circulated in the SCPF newsletter
Structural Analysis Principles
The lab restricts itself to analysis with structure as the subject. It does not single out specific municipalities, councils, mayors, or operators in an evaluative-disadvantageous context. National distribution, scheme design, propagation patterns, and revenue structures are within scope; individual accountability is not the lab's role.
Numbers are presented as national distributions. Where municipal-level or political-group-level aggregates are used, they are framed as observations, and evaluative adjectives (worst, superior, inferior, etc.) are avoided.
Verifiability
Every cited statistic includes source URL, access date, and granularity. Aggregation queries (e.g., on BigQuery) are disclosed as reproducible queries with the date of result retrieval in the methodology section. Legal citations are checked against e-Gov for canonical wording; summary and omission are avoided.

Candidates for next articles
The following are candidates for the next round, to be initiated after the editor's selection.
- Structural analysis of the "three walls" of small concession — abstracting the revenue structures of Japanese small concession (zero-burden type, subsidy-combined type, FTK type, LABV type) from the 15 cases in PMC's April 14, 2026 seminar, and mapping them onto local conditions
- Geography of public asset utilization debate in local councils — in collaboration with Machikarte (the neutral council speech data infrastructure), analyzing the national distribution of debate on "closed school utilization," "underused facilities," "Park-PFI," and "PFI" (see the cross-reference document
docs/labs-public-asset-ppp-machikarte-cross-reference.md) - Methodological review of WTP estimation for PFS — examining the limits of Cabinet Office guidelines and the practitioner knowledge of K-three and others, to formulate a procedure for municipalities to estimate WTP independently
- Closed school utilization in urbanization control zones — operational realities of museum law registration, district plans, and Regional Revitalization Act exemptions, and the institutional requirements of breakthrough cases
Each article will keep structure as its subject and pass through editorial committee review before publication.
Cross-Reference
The lab cross-references with other ISVD labs on the following themes.
- Machikarte Lab's "hollowing of debate / structuring of silence" and the geography of public asset utilization debate (cross-reference document shares the methodology for extracting council speeches)
- Social Design Foundations Lab's EBPM and participatory design literature, connected to the scheme design of PFS and sounding
- Agnotology Lab's "structuring of silence" connected to the structure under which public asset utilization debate does not surface
