Adaptive Reuse of Decommissioned Oil Terminals and Refineries — Comparing Ten Domestic Cases and Three International Precedents
Japan's decommissioned refineries and oil terminals have come one after another: Cosmo Sakaide in 2013, JX Muroran in 2014, ENEOS Osaka in 2020, ENEOS Wakayama in 2023, Seibu Oil Yamaguchi in 2024. Most sites have been repurposed as logistics hubs, petrochemical bases, or Sustainable Aviation Fuel (SAF) production facilities — cultural and architectural adaptive reuse remains virtually absent domestically. Internationally, three landmark precedents exist: TANK Shanghai, Gasholders London, and the Vienna Gasometers. This note compares ten domestic cases and three international cases to examine the prospects for architectural adaptive reuse in Japan.
27,000 Defunct Gas Stations and Subsurface Tank Legacies: A Typology of Shrinking Assets
Japan's gas stations peaked at 60,421 stations at the end of fiscal 1994 and fell to 27,009 stations by the end of fiscal 2024 — roughly 33,000 closures over thirty years. Under Fire Prevention Notice No. 78 (消防危第78号), underground tank disposal after closure follows the principle of removal first, with in-place filling permitted only when unavoidable. In practice, the cost burden has made in-place filling the common choice. This note classifies the 'subsurface infrastructure legacy' subtype within the larger category of shrinking assets, reading both the legal framework and on-the-ground reality.
Airport Concession Revenue Structure — The 'Viability Threshold' Revealed by 12 National-Government Airports and the Conditions for Private Entry
Since 2016, concessions at national-government-managed airports—including Sendai, Takamatsu, Fukuoka, and the seven Hokkaido airports—have advanced steadily. Yet only 12 of Japan's 98 airports have completed concession arrangements. This article analyzes the three revenue streams—passenger aviation revenue, commercial revenue, and landing fees—and examines the scale conditions under which financial viability is achievable.
Park-PFI Seven Years of Revenue Structure — Conditions for Revenue Facilities in Urban Parks and the Three-Type Divergence
Seven years after the 2017 amendment to the Urban Park Act (都市公園法), revenue facilities established under Park-PFI (the public solicitation and management system — 公募設置管理制度) have surpassed 300 nationwide. Yet a clear structural gap exists between financially viable projects and those that fail to achieve viability, driven by location, facility scale, and return-payment design. This article classifies cases into three types—standalone revenue facility, park-improvement allocation, and mixed-development—and analyzes under what conditions each type functions.
The PPP Desk Divide — Structural Gaps in Municipal Internal Capacity and Their Impact on Project Formation
The Cabinet Office has established PPP desk programs, expert dispatch, and advisory frameworks to support local governments in advancing PPP/PFI. Yet a clear structural divide separates municipalities that generate projects from those that do not — driven by staff expertise, mayoral commitment, and the sustained functionality of desk operations. This analysis examines how internal capacity gaps translate directly into project formation gaps.
Risk Allocation in PPP/PFI Projects — How Poor Matrix Design Drives Project Failure
Risk allocation is the most contentious element of PPP/PFI contract design. Using three risk categories — demand risk, construction cost risk, and price escalation risk — this analysis examines how the distribution of risk between public and private parties shapes project viability and long-term sustainability. Drawing on domestic failure cases, it extracts recurring patterns of design failure and sets out the principles for sound matrix design.
Structural Comparison of Three Water Concession Cases — Divergence Conditions of Operational Transfer in Miyagi, Hamamatsu, and Susaki
The three cases of Miyagi Prefecture (integrated water, industrial water, and sewerage), Hamamatsu City (sewerage), and Susaki City (water supply) represent distinct design types within Japan's water and sewerage concession landscape. This analysis compares how the transfer of operational rights to private operators functions across profitability, service standards, and risk allocation, and maps the design choices available to municipalities heading into the 2030s.
Regional Distribution of 'Vacant Houses' and 'Public Facilities' Debate in Japanese Local Assemblies — A Seven-Year Structural Analysis Across 1,320 Municipalities
Across the machikarte corpus of roughly 125 million local assembly speech records (2018-2024 window, up to 1,320 Japanese municipalities), this article aggregates mentions of vacant-houses (akiya), public-facilities, and school-closure terms. Akiya mentions follow a U-shaped recovery — 34,573 in 2018, falling to 24,100-25,791 in 2019-2021, and recovering to 34,847 in 2024. Public-facility mentions reach a seven-year high in 2024 (67,014). Co-mentions of 'small concession' rise from 2 in 2023 to 36 in 2024. The article reads these as structural observations, not as evaluations of individual assemblies.
Structural Analysis of Japan's Small Concession Three Walls — Revenue Structure Types and Breakthrough Patterns
MLIT's 2026 handbook 'The Case for Small Concessions' identifies three structural barriers: the image wall, the partner wall, and the commercialization wall. This analysis cross-references all 15 cases from the PMC April 2026 seminar to classify Japan's small concession revenue structures — zero-burden type, subsidy-hybrid type, FTK type, and LABV type — and clarifies which conditions align with which type.
Public Asset Utilization Lab — Hypotheses and Scope
An introduction to the Public Asset Utilization Research Lab (ISVD-LAB-005): its problem framing, analytical scope, and methodology. The lab examines PPP/PFI, small concessions, Park-PFI, PFS and related schemes, and the structural difficulties in collaboration among local operators, experts, and municipalities — drawing on primary sources from the Cabinet Office, MIC, MLIT, and MEXT, and on cases from across Japan.
The 'Softification' of Public Services — A Paradigm Shift from Facilities to Services
Japan's infrastructure maintenance costs will reach ¥190 trillion over the next 30 years, and 75% of road bridges will exceed 50 years by 2040. Public asset discussions have focused on 'hardware' rehabilitation, but what residents need is services, not buildings. With 611 municipalities offering e-libraries, 17.13 million convenience store certificate issuances, and 96% school athletic facility sharing, the structural shift from facilities to services is already underway.
Structural Analysis of Abandoned School Small Concessions — The Institutional–Execution Gap Behind 1,951 Unused Schools
Of Japan's 7,612 abandoned schools, 1,951 remain unused. MEXT officially recommends small concessions, and the 10-year rule eliminates subsidy repayment obligations. Yet schools sit empty. This analysis examines the structural barriers across regulation, funding, and human capital that prevent the simplest form of PPP from being implemented.
Corporate Hometown Tax at ¥63.1 Billion — How Personnel Dispatch Is Reshaping Public Asset Regeneration
Japan's corporate hometown tax donations reached ¥63.1 billion in FY2024, with 157 personnel dispatched to 119 municipalities. With up to 90% tax relief and human capital costs treated as deductible donations, this system can solve both funding and staffing gaps in public asset regeneration — but a fraud case is forcing structural reform.
PFS Adoption at 9% — Why Municipalities Cannot Embrace Pay-for-Success Despite Complete Institutional Infrastructure
Only 154 of Japan's 1,700 municipalities have implemented Pay-for-Success (PFS) contracts — a 9% adoption rate. Despite comprehensive guidelines, subsidies, and expert dispatch programs from the Cabinet Office, three structural barriers — WTP calculation, logic model design, and internal consensus building — prevent municipalities from taking the first step.
The Structural Gap in Priority Review Regulations — Behind the 82% Adoption Rate Lies a System That Doesn't Work
Japan's Cabinet Office has promoted Priority Review Regulations for PPP/PFI adoption, achieving an 82.1% adoption rate among cities with 200,000+ residents. Yet a structural gap exists between adoption and actual implementation. This analysis cross-references population-stratified data, Ministry of Internal Affairs surveys on institutional hollowing, and pioneering cases to quantify why regulations exist but fail to function.
