Park-PFI Succeeds Even in Municipalities of 23,000 — Strategies for Small-Scale Local Governments [2026 Edition]
For local government officials: Over 23% of Park-PFI adoptions are in municipalities under 100,000 population. This guide explains why Ninohe City (population 23,000) succeeded, six success patterns for small-scale cases, area requirements starting from 0.25 ha, and how to design solicitations where local businesses can lead.
TL;DR
- Over 23% of Park-PFI adoptions are in municipalities under 100,000. The evidence refutes the misconception that Park-PFI is only for large cities.
- Small-scale success follows six patterns: regional resource, problem-solving, glamping, vertical construction, package bundling, and community development company models.
- Large operators often do not bid on small projects, creating space for local businesses. Evaluation Item 2 — local business participation — is the key design lever.
Dismantling the "Too Small" Misconception
When municipalities begin exploring Park-PFI (the Public Solicitation Management System), many arrive early at the conclusion that they are "too small." The reasoning typically runs: "Private operators won't come," "the economics won't work," or "this framework is only suited to large parks."
The empirical record, however, contradicts this assumption.
As of March 31, 2025, 165 parks nationwide have adopted Park-PFI. Disaggregating those adoptions, municipalities with a population under 100,000 account for more than 23% of all cases. That proportion directly refutes the narrative that Park-PFI is designed for large cities.
More specifically, the case of Iwate Prefecture's Ninohe City — population approximately 23,000 — stands as a symbolic proof of small-municipality viability. Kadaru Terrace Kanetaichi opened in March 2022 and received the Japan Society of Civil Engineers Design Award Excellence Prize in 2023.
This article provides a detailed account of the strategies that allow small municipalities to realize Park-PFI — covering the six success patterns, the reality of area eligibility, and the solicitation design that enables local businesses to take the lead.
Six Small-Scale Success Patterns
Regional resource, problem-solving, glamping, vertical construction, package bundling, and community development company models — their characteristics and preconditions.
Park-PFI projects that succeed in small municipalities share recognizable patterns. Analyzing documented cases yields six distinct types.
Pattern 1: Regional Resource Model
Definition: Cases in which a region-specific resource — hot springs, natural scenery, historic assets — forms the revenue foundation, attracting private operators through its irreplaceability.
Representative case: Ninohe City, Iwate Prefecture — Kadaru Terrace Kanetaichi
Ninohe City has approximately 23,000 residents and used a neighborhood park (standard 2-ha scale) for this project. The lead operator was "Kadaru Mirai," a locally funded quasi-public urban development company, which formed a special purpose vehicle (SPC) and simultaneously executed the replacement of a deteriorating municipal hot-spring facility and the Park-PFI project. The business composition — hot springs, sauna, overnight accommodation, restaurant, and indoor pool — is a revenue model anchored in the irreplaceable local resource of the onsen.
The enabling condition for this pattern is the presence of an irreplaceable local resource. Parks adjacent to onsen, cultural properties, or scenic attractions hold built-in drawing power. Customers visit for the resource itself, independent of whether a large national operator installs a standardized facility.
Pattern 2: Problem-Solving Model
Definition: Cases that position social infrastructure — childcare, disability welfare, medical facilities — as the "revenue facility," rather than food and beverage businesses.
Representative case: Mutsu City, Aomori Prefecture — Yanagimachi Children's Park
A licensed nursery school was installed in a small neighborhood park, simultaneously resolving a childcare waitlist problem and revitalizing the park. The nursery operator obtained an installation management permit and built and operates the nursery inside the park.
The primary strength of this pattern is its independence from footfall. Food and beverage operations fail at low-traffic locations, but nurseries and welfare facilities are supported by institutionally guaranteed demand, making them viable even in lower-traffic regional cities.
Municipalities that envision only food service as a viable business type may be systematically overlooking this pattern.
Pattern 3: Glamping Model
Definition: Cases built around glamping (experiential accommodation), which delivers high revenue per guest at modest initial investment.
Representative case: Mutsu City, Aomori Prefecture — PARK DAIKANYAMA
Mutsu City (population approximately 56,000) saw a local real estate company, Mutsu Real Estate Trading Center, serve as the lead operator, revitalizing an underutilized park with trailer-house accommodation, food and beverage service, and a dog run. The branding as "the northernmost glamping site on Honshu" creates a marketable claim to scarcity.
Glamping's defining characteristic is its low capital requirement. Trailer houses and glamping tents require far less investment than permanent construction, shortening the payback period. Parks adjacent to agricultural land or coastline can command premium pricing through the promise of non-everyday experience.
Pattern 4: Vertical Construction Model
Definition: Cases that resolve small-footprint constraints by stratifying the program across multiple floors, expanding effective revenue-generating area.
Representative case: Beppu City, Oita Prefecture — Haruki River Park
On a site of approximately 0.92 ha — well under one hectare — this project created western Japan's first vertical urban park: a ground-floor supermarket beneath a second-floor artificial turf sports ground and café. The lead operator was "Minerva," a locally formed SPC combining a local sports club and a local retailer. The city's annual revenue from this project is approximately ¥14 million.
Even a park initially dismissed as "too small to be viable" can expand its revenue-generating floor area through vertical construction. This pattern is particularly effective for constrained urban infill sites.
Pattern 5: Package Bundling Model
Definition: Cases where multiple small parks, none of which are individually economically viable, are combined into a single solicitation package.
Representative case: Hachioji City, Tokyo — Takakura Park and four other parks
Five 0.25-ha street-block parks were bundled together and solicited as a unified "play space where ball games are permitted" project. Even the smallest-category street-block parks, each individually too small to attract private interest, reach a scale with meaningful commercial potential when consolidated.
For municipalities managing several street-block parks, consolidating them into a single solicitation reduces the barrier to private entry — an approach transferable to small-municipality contexts.
Pattern 6: Community Development Company Model
Definition: Cases in which a locally funded SPC or community development company serves as the lead operator, designing a structure that keeps revenue and employment circulating within the region.
Representative case: Ninohe City, Iwate Prefecture — Kadaru Terrace Kanetaichi (overlap with Pattern 1)
Kadaru Terrace Kanetaichi also qualifies as Pattern 6. By positioning "Kadaru Mirai" — a locally funded, quasi-public community development company — as the lead operator, the project avoided the risk of management flowing to large external corporations, and instead ensured that jobs and revenue circulated locally.
The enabling condition for this pattern is the existence of a "community development company" or a "capable SPC sponsor" within the region. Where a locally funded entity — backed by a chamber of commerce, agricultural cooperative, credit union, or local businesses — already exists, that organization can anchor an SPC.
Area Eligibility in Practice
The Hachioji City case showed 0.25-ha street-block parks qualifying for national grants. The Beppu City Haruki River Park succeeded at 0.92 ha.
Another widespread misconception is that "our park is too small to qualify for national grants." A review of the actual requirements is warranted.
Minimum Area Requirements for National Grants
There is no statutory minimum area for installing publicly solicited park facilities under Park-PFI. Any park covered by the Urban Park Act is theoretically eligible from street-block park scale (standard 0.25 ha) upward.
The Integrated Social Infrastructure Grants — which subsidize designated park facility improvements — do not establish a blanket minimum area threshold. Projects are evaluated on their content, necessity, and expected impact.
The Hachioji City case — five 0.25-ha street-block parks bundled into a package — provides direct empirical confirmation. Each individual park is the smallest standard category, yet the package qualified for national grant eligibility.
Beppu City's Haruki River Park (approximately 0.92 ha) also qualified as a national grant-eligible project at under one hectare, demonstrating that the assumption "one hectare or larger is required for grant eligibility" is factually incorrect.
Floor Area Implications of the Site Coverage Provision
Upon receiving Park-PFI certification, publicly solicited park facilities may utilize site coverage up to 12%, but the actual floor area this generates depends on the park's total area.
For a 0.25-ha (2,500 m²) park, 12% site coverage yields a maximum of 300 m² of building floor area — sufficient for a small café or retail shop, but too small for accommodation. A 1-ha (10,000 m²) park yields up to 1,200 m², more easily supporting mixed-use programs.
For smaller-footprint parks, Pattern 4 (Vertical Construction) can expand effective revenue floor area within the site coverage constraint.
Solicitation Design for Local Business Leadership
Scoring design for Evaluation Item 2 and SPC formation methodology.
The belief that "large companies must lead" or that "local businesses lack the track record" is also largely misconception. Thoughtful evaluation criteria design can create an environment in which local businesses compete viably as lead operators.
Strategic Use of Evaluation Item 2: Local Business Participation
The MLIT guideline's Evaluation Item 2 covers "implementation structure," and explicitly includes "local business participation" as a sub-criterion. Increasing the point weight assigned to this criterion raises the incentive for local business involvement.
In all small-municipality cases reviewed here — Mutsu City, Ninohe City, and Beppu City — the lead operator was a local company or locally formed SPC. National large-scale operators did not serve as leads. This was not coincidental: the solicitation design was structured to produce this result.
Designing Consortium-Type SPCs
When local businesses serve as lead operators, forming a consortium (joint venture) effectively compensates for gaps in experience and track record.
A functional consortium structure typically follows this pattern:
| Role | Entity Type | What They Contribute |
|---|---|---|
| Lead operator | Local community development company / chamber of commerce / local construction firm | Regional relationships, local credibility, community network |
| Facility design and construction | Local construction company or design firm | Design and construction track record |
| Operational expertise | Food service chain or hot-spring facility operator | Revenue facility management experience |
| Financial capacity | Local bank or credit union | Financial soundness and funding capacity |
This "hybrid" formation — local leadership paired with externally sourced operational know-how — is well positioned to score highly on Evaluation Item 2 (local participation) while also demonstrating sufficient operational and financial capacity.
The contrast with large-scale cases like the Kaiseizan Park project (where Daiwa Lease led) is clear: smaller projects naturally tend toward the inverse pattern, where local entities lead.
Eligibility Requirement Design
Setting excessively high track record requirements in the solicitation guideline's participation eligibility section (Clause 10) raises barriers that exclude local businesses. Rather than requiring "documented experience operating park facilities within the past five years," framing the condition as "documented experience operating facilities comparable to parks" broadens eligibility for local operators.
Strategy for Projects Large Operators Skip
Conditions that reduce large-operator interest and how regional actors can fill that space.
Projects that are difficult for large consultants and operators to justify commercially represent opportunities for local businesses and smaller specialist firms.
Conditions That Reduce Large-Operator Interest
The following conditions, in combination, tend to reduce large-operator participation appetite:
- Small project scale: When advisory fees fall below ¥5 million, or revenue facility sales are modest, the return-on-investment for large firms is insufficient.
- Remote or rural location: High travel costs and the absence of local networks put large firms at a competitive disadvantage.
- Local business preference in the design: When evaluation criteria incorporate local participation bonuses, operators with local networks hold a structural advantage.
- Sounding participation incentives: When operators receive bonus points for participating in market sounding, those who engaged early — typically local actors — enjoy a compounding advantage.
These conditions can be deliberately designed into solicitations, creating a structure where "small project = local actors lead."
Domains Where Small Municipalities Can Excel
- Municipalities under 50,000 population, particularly towns and villages: Large consultants show limited interest; small PPP specialists and local firms compete more favorably.
- Parks adjacent to region-specific tourism assets: Branding requires local knowledge, giving local actors a genuine advantage.
- Problem-solving business types (childcare, welfare): Operators with deep knowledge of local social challenges are naturally better positioned.
Support Programs for Small Municipalities
Feasibility study support and Integrated Social Infrastructure Grants.
The following support programs are available to small municipalities pursuing Park-PFI.
Integrated Social Infrastructure Grants
A national subsidy for designated park facility improvements (park paths, plazas, benches, etc.). Because the program involves adoption criteria, early consultation with the relevant MLIT Regional Development Bureau is important.
National Feasibility Study Support
A program providing partial national funding for the cost of market sounding and feasibility studies. For small municipalities, advisory fees of ¥5M–¥20M represent a significant fiscal burden, making this support program highly worth pursuing.
For detailed procedures and application requirements, refer to the MLIT Urban Bureau's Park-PFI resource page or contact the competent MLIT Regional Development Bureau directly.
Urban Development Fund (Vitalization Promotion Fund)
Where local governments lend project capital to private operators, the national government provides half the amount as a subsidized loan. The relative benefit of this mechanism is greater for smaller-scale projects.
Alternative Approaches When Park-PFI Is Not Currently Viable
If a feasibility study concludes that Park-PFI is not viable at this time, park activation options still exist.
Phased approach: Conduct a lightweight sounding to gauge market interest first. If interest is weak, make targeted investments to improve the park environment and draw power, then commission another feasibility study two to three years later.
Combining with the Designated Manager System: Even where Park-PFI is not viable, the designated manager system can channel private-sector capacity into park management, partially realizing the intent of public-private partnership. This can also be framed as a preparatory step toward eventual Park-PFI adoption.
Exploring Small Concessions: If the park contains facilities not subject to the Urban Park Act — such as a former community hall or closed school annex — those facilities may be separately commercialized as small concessions. Refer also to What Is a Small Concession?.
Before concluding that "small scale means Park-PFI is impossible," examine each assumption underlying that conclusion. Is the barrier "size," or "location conditions," or "solicitation design"? Decomposing the question often reveals that the actual barrier is solvable.
