What Is Sounding?
Definition, purpose, and overview of the three types. Why pre-procurement dialogue is necessary
Types of sounding (market, pre, and trial)
3 Types
Each differs in timing and purpose. Phased implementation is the success pattern

Before Procurement
Before requirement design — the most critical step for preventing zero-applicant outcomes
Trial sounding duration (Park-PFI specific)
Days to Weeks
Generates actual visitor and operational data before the formal tender is issued
Sounding is a collective term for informal dialogue methods used by government agencies to consult with private operators when considering the revitalization of public facilities or the design of public-private partnership projects. Conducted before formal procurement (proposals or bids), sounding enables agencies to understand private-sector needs, concerns, and possibilities — improving the accuracy and viability of procurement requirements.
The Ministry of Land, Infrastructure, Transport and Tourism and the Cabinet Office recommend sounding as part of Park-PFI and Small Concession implementation. The Park-PFI Utilization Guidelines include detailed sounding implementation procedures.
Why Sounding Is Necessary
A common problem in public facility revitalization procurement is that procurement requirements misalign with market demand. Typical failure patterns include:
- Zero applicants: Requirements that make business viability impossible, or facilities where private operators have no genuine interest
- Condition mismatches: Contract terms (duration, renovation cost burden, lease rates) that fall below operators' investment decision thresholds
- Business type mismatch: The municipality's expected business type differs from what the private sector can actually execute
Sounding is designed to detect and resolve these risks during the procurement design stage.
Overview of the Three Types
| Type | Timing | Primary Purpose | Deliverable |
|---|---|---|---|
| Market Sounding | Before procurement design (earliest stage) | Market research, interest confirmation | Market research report, published summary |
| Pre-Sounding | After draft requirements are prepared | Final requirements check and modification | Revised draft requirements |
| Trial Sounding | Proof-of-concept before procurement (Park-PFI specific) | Proof-of-concept testing, feasibility confirmation | Trial results report, evaluation |
Market Sounding
Market research before procurement design. Procedures, question design, and disclosure points
Market sounding is conducted before beginning procurement requirement design. The primary goals are to understand "what kinds of businesses could succeed at this facility and location" and "how much interest do private operators actually have."
Implementation Procedure
Step 1: Design the Implementation Framework
Prepare in advance:
- Overview of the target facility (location, scale, deterioration condition, current status)
- Potential directions being considered (café, sports, welfare, etc.)
- Dialogue format (individual sessions or group format)
- Eligibility requirements (industry, scale, track record)
- Confidentiality and information handling policy
Step 2: Announcement and Participation Recruitment
Publicize broadly through the municipality's website and relevant organizations (chambers of commerce, industry associations). Collect applications from interested operators.
Step 3: Individual Dialogue Sessions
Conduct individual dialogues with participating operators (approximately 30–60 minutes per company). Record opinions and proposals, and ensure sessions are held in separate rooms at separate times to prevent information leakage between competitors.
Key topics to cover in dialogue:
- Assessment of the facility and location, and perceived challenges
- Envisioned business model and financial viability estimates
- Conditions for procurement participation (term, renovation cost burden, maximum lease rate)
- Concerns and risk perceptions
Step 4: Summary and Disclosure
Compile market research findings and publish a summary. The names of participating operators and their individual opinions are generally not disclosed (published in anonymized, aggregated form).
Pre-Sounding
Final review of draft procurement requirements. Pre-disclosure materials, individual dialogue, and feedback integration
Pre-sounding is conducted after draft procurement requirements have been prepared, as a final verification stage before launching procurement. After incorporating market sounding findings into a requirements draft, pre-sounding verifies whether the proposed conditions will actually attract applicants.
Differences from Market Sounding
| Dimension | Market Sounding | Pre-Sounding |
|---|---|---|
| Timing | Before requirements design | After requirements draft is prepared |
| Dialogue content | Open-ended opinions and proposals | Feedback on specific requirements draft |
| Deliverable | Market research report | Revised requirements draft |
| Participants | Broadly recruited | Recruited again, often including market sounding participants |
Pre-Sounding Key Points
In pre-sounding, the draft requirements are shared in advance (pre-disclosure) and feedback is solicited. Materials typically include:
- Detailed facility information (drawings, structure, equipment condition)
- Intended direction for the project
- Proposed terms (duration, lease rates, cost allocation)
- Overview of evaluation criteria
Requirements are revised based on private-sector feedback, and the changes are published to ensure transparency. A response that "collected opinions but changed nothing" generates mistrust in government and should be avoided.
Trial Sounding
Proof-of-concept testing specific to Park-PFI. Duration, cost burden, and evaluation structure
Trial sounding is a method specifically recommended by MLIT, primarily for Park-PFI projects. Before formal procurement, operators conduct trial businesses (markets, cafés, events) in the actual park for a set period, generating real data on feasibility, visitor attraction, and operational challenges.
Key Features of Trial Sounding
Duration: Several days to several weeks (seasonal trials are also possible)
Cost allocation: Operators retain revenue earned during the trial. Venue setup, cleaning, and insurance costs are generally operator-borne, though some municipalities provide partial support.
Evaluation content:
- Actual visitor numbers and revenue scale
- Appropriateness of location and traffic flow within the park
- Reactions from nearby residents and park users
- Operational challenges (parking, noise, waste management, etc.)
Use of results: Trial results are incorporated into procurement requirement design. To prevent trial participants from gaining unfair advantages in subsequent procurement, results must be published in a form accessible to all potential applicants.
Trial Sounding Implementation Examples
Running a trial café or market event in an urban park can reveal issues such as "weekends attract visitors but weekdays are difficult" or "rain-weather tent installation is necessary," and those findings can then be written into the procurement conditions before formal solicitation.
Fairness and Information Management
Protecting participant information, preventing leaks to competitors, and designing disclosure scope
The most critical concern for government agencies conducting sounding is ensuring procedural fairness. Sounding participants must not gain advantages in subsequent procurement.
Specific Management Rules
Uniform information disclosure: Information disclosed during sounding (facility details, draft conditions, etc.) must be provided to all applicants under identical conditions in the subsequent procurement.
Protecting individual information: The names, proposals, and participation status of operators are generally kept confidential. If specific details ("Company A said they would participate if the lease rate were below X") leaked to other operators, it could create strategic advantages or disadvantages.
No restriction on procurement participation: Having participated in sounding is not itself a reason to restrict participation in procurement. However, if a specific operator's idea was incorporated into procurement requirements, that operator may gain an unfair advantage. In such cases, requirements should be generalized (not designed in ways only that operator can fulfill).

What to do next
When considering reuse of idle facilities, examine their condition, local demand and operator interest.
| # | What to check or consider | Responsible team or contact |
|---|---|---|
| 1 | Review idle facilities and local demand. Compare building condition and location with uses needed in the area | Asset management team |
| 2 | Check seismic assessment and asbestos survey results for candidate facilities. If surveys are missing, determine their scope and how to commission them | Facilities team |
| 3 | Use MLIT's platform to gather information. Membership is free and provides case studies and notices about grants and expert dispatch calls | Official platform website |
| 4 | Ask operators about their interest and requirements. If a standalone project is difficult, consider cooperation with neighbouring municipalities | Market sounding and neighbouring municipalities |
| 5 | Compare operating rights, leasing and designated management in light of operator feedback. Choose a method suited to the facility's use, finances and public-private responsibilities | Responsible department and asset management team |
Platform membership provides access to information about expert dispatch and grant calls. Before applying, check eligibility, available support and deadlines in the call documents.
