Adaptive Reuse of Decommissioned Oil Terminals and Refineries — Comparing Ten Domestic Cases and Three International Precedents

This note is the international comparison component of the Public Asset Utilization Research Lab.

In 2023, the ENEOS Wakayama Refinery halted petroleum refining operations. Its site area: 2.48 million m² (2,480,000 m²). The site is now slated for conversion into a Sustainable Aviation Fuel (SAF) production facility under the banner of the "Future Environmental Supply Base" concept.

In 2024, Seibu Oil's Yamaguchi Refinery closed. Its crude oil processing capacity: 120,000 barrels per day. The site is planned for conversion into a carbon-free energy supply center, technology development demonstration center, and biomass resource recycling center under the GX Seibu concept.

Similar closures and functional conversions have followed at Cosmo Sakaide in 2013, JX Muroran in 2014, and ENEOS Osaka in 2020. The dominant pattern for Japan's refineries has solidified: cease refining, then convert to an energy hub or logistics base.

Internationally, a different model has taken hold. TANK Shanghai (formerly the aviation fuel tanks of Longhua Airport), Gasholders London (formerly the King's Cross gas tanks), and the Vienna Gasometers (four former municipal gas tanks) all represent precedents of industrial heritage converted into cultural facilities and mixed-use residential complexes.

This note compares ten domestic cases and three international cases to examine the prospects for architectural adaptive reuse of Japan's decommissioned oil terminals and refineries.

Confidence A: 4 cases (Wakayama, Muroran, Seibu Oil Yamaguchi, Sakaide). Confidence B: 5 cases. Confidence C: 1 case. Cases #8 and #10 are reference listings only (closure unconfirmed); case #9 is a reference listing only (primary source unverified). Confirmed closure count: 7 cases (#1–#7).

Sorting the ten cases by the character of their conversion yields four categories.

The conspicuous gap: cultural and architectural adaptive reuse

Among the ten cases, none involve conversion to cultural facilities, museums, or mixed-use residential complexes. The path from "ceased refining" to "another industrial function" is well-trodden. The path from "industrial heritage" to "cultural asset" remains unexplored in Japan. However, this observation of "no precedent" is bounded to oil refineries and oil terminal facilities specifically. Adjacent industrial heritage categories — gas tanks, coal mines, steelworks (e.g., Yokohama gas tank sites, Kitakyushu Space LABO) — may have their own conversion precedents and are outside this survey's scope.

Case A1: TANK Shanghai (上海油罐艺术中心)

TANK Shanghai stands as the world's foremost example of the direct conversion of "abandoned fuel tanks" into "a contemporary art museum." The five large tanks now house a mixed cultural venue including teamLab exhibitions.

Case A2: Gasholders London

Gasholders London is the definitive example of inserting residential function while preserving the industrial heritage frames. The cast-iron frames were dismantled in 2001 to allow for the Channel Tunnel Rail Link, restored in Yorkshire, returned to King's Cross, and reassembled — a painstaking process that made the final result possible, with the project completing in early 2018.

Case A3: Vienna Gasometers (Gasometer City)

Vienna Gasometers is a rare case of four architects each taking charge of one unit of the same industrial heritage. Each block carries its own design language while the ensemble coheres as "Gasometer City."

Reading the three cases through the five layers of meaning inversion (see The Five-Layer Methodology of Meaning Inversion for Shrinking Assets), three shared principles emerge.

Note on comparability: All three cases (China, UK, Austria) involve privately or semi-publicly owned facilities — a context quite different from Japan's typical situation, where oil companies retain ownership of the land and structures while considering reuse options. The design principles below are useful as reference grammar for architectural and spatial design, but should not be read as direct precedents for project feasibility in Japan.

Principle 1: Structural Preservation as the First Priority

In every case, demolition of the existing tank or frame structures was kept to a minimum. TANK Shanghai preserved the forms of all five tanks before opening as a museum. Gasholders London dismantled its three frames, had them restored, moved them, and reassembled them. The Vienna Gasometers preserved the four brick exterior walls and built new interiors within.

This aligns with Lacaton & Vassal's principle: "Never demolish. Always transform, with and for the inhabitants." (Harvard GSD 2022)

Principle 2: Explicit Declaration of "Meaning Inversion" from the Original Function

TANK Shanghai inverted "fuel storage" — a function the city preferred to hide — into "contemporary art" — a function the city can take pride in. Gasholders London inverted industrial infrastructure into luxury residences. The Vienna Gasometers inverted a peripheral industrial district into a mixed urban center of housing, commerce, and culture.

The more explicitly the intention to invert is stated, the more powerfully an adaptive reuse project functions as a device for rewriting the city's memory.

Principle 3: Mixed-Use Programming

None of these projects were designed as single-use facilities. TANK Shanghai: museum + park + bookstore + education center + restaurant. Gasholders London: residences + shared facilities. Vienna Gasometers: residences + commercial + office + entertainment.

Distributing the risk of single-use dependence (demand volatility, operational failure) and drawing diverse visitors through urban programming are built in together.

The patterns visible across the ten domestic cases — petrochemical conversion, carbon-free hubs, chemical recycling — are all "functional conversions within the petroleum industry." No domestic case follows the international precedents' path of "industrial heritage → cultural asset."

This means architectural adaptive reuse in Japan is an area with zero precedent. The scope for pioneering is real; so is the risk. Three issues will determine feasibility.

Issue 1: Fire Defense Act Decommissioning Procedures for Hazardous Materials

Decommissioned refineries and oil terminals are designated hazardous material facilities under Japan's Fire Defense Act. Reuse requires hazardous material decommissioning procedures (filing a discontinuation notice, measuring residual gases, internal cleaning, inert gas filling, and determining demolition or retention). Practical costs run 2 to 5 million yen per facility (see Abandoned Gas Stations: 27,000 Sites and Underground Tank Legacies), and scale considerably higher for large installations.

Issue 2: Soil Contamination Survey Costs

Under Japan's Soil Contamination Countermeasures Act, altering terrain on 900 m² or more upon closure of a designated facility using hazardous substances triggers a mandatory notification obligation. Since refineries and oil terminals span from tens of thousands to millions of square meters, comprehensive site surveys carry costs in the hundreds of millions of yen. This cost burden is the primary obstacle to conversion.

Issue 3: Alignment with Land Use Zoning Regulations

Refineries and oil terminals are typically located in industrial or exclusively industrial zones. Converting them to cultural facilities or residences requires a zoning change under the City Planning Act. Zoning changes run through a municipality's comprehensive plan and Urban Planning Council — a long process that effectively takes five to ten years.

Implication 1: Room for institutional frameworks supporting an "industrial heritage → cultural asset" pathway

The "convert industrial heritage into a cultural asset" pathway demonstrated by the three international cases has no institutional support in Japan. The notification obligation under the Soil Contamination Countermeasures Act, hazardous material decommissioning procedures under the Fire Defense Act, and zoning changes under the City Planning Act function as a triple barrier. There is room to design something like an "industrial heritage adaptive reuse special zone" that eases all three.

Implication 2: As a vehicle for oil companies' CSR repositioning

The ENEOS Wakayama and Seibu Oil Yamaguchi cases suggest oil companies are shifting toward framing site reuse as "community-linked CSR." Providing the institutional option of cultural and architectural use as a receptor for this shift may draw out oil companies' willingness to pursue it.

Implication 3: Starting with smaller-scale experiments at the gas station level

Conversion experiments at large-scale refineries (tens of thousands to millions of m²) carry high cost and risk. A more realistic path is architectural adaptive reuse experiments at decommissioned gas stations — smaller sites of 500 to 1,000 m², 27,000 of them across the country. ISVD's Quiet Town Project, which explores the concept of "a decommissioned gas station as an observation post," represents one variant of this small-scale experimental approach.

Japan's decommissioned refineries and oil terminals are being converted one after another into "energy hubs," "logistics bases," and "chemical recycling facilities." That direction makes rational sense within the petroleum industry — but the opportunity to rewrite the city's memory is being left on the table.

TANK Shanghai's 60,000 m², Gasholders London's three frames, the Vienna Gasometers' four tanks. What these international precedents demonstrate is the simple possibility that industrial heritage can be redefined as cultural asset. Japan's 27,000 abandoned gas stations and the several dozen decommissioned refineries and oil terminals are candidates for exactly that possibility.

The starting point: lay the cases out side by side. Ten domestic, three international, thirteen total. Next: read them through the five layers of meaning inversion. Then: connect them to policy proposals. What the ISVD Public Asset Utilization Research Lab is building is the research foundation that links these three stages.
