Japan Sustainable Aviation Fuel (SAF) market is estimated to record a consumption of 245 thousand tons in 2028, further anticipated to reach a volume of 4,480 thousand tons by 2033 with a CAGR of 43.8% during the forecast period.
Government mandate targeting 10% SAF usage by 2030 for international flights departing Japan.
Japan's policy mandating a 10% usage of Sustainable Aviation Fuel (SAF) for international flights departing the country by 2030 is emerging as a significant catalyst for the Japan Sustainable Aviation Fuel (SAF) Market. This mandate provides a measurable demand baseline, moving beyond voluntary commitments from airlines and encouraging refiners, airlines, fuel suppliers, and investors to ramp up commercial-scale production.
The international aviation sector in Japan consumes approximately 10–12 million kiloliters of jet fuel each year. Meeting the 10% SAF target will necessitate nearly 1 million kiloliters of SAF annually by 2030, a volume that greatly surpasses current domestic production capabilities. This situation underscores the urgent need for refinery upgrades, the establishment of new SAF facilities, and diversified feedstock sourcing.
Key companies such as ENEOS, Cosmo Energy, Idemitsu Kosan, and Euglena are already announcing projects aimed at boosting domestic SAF production. Airlines like Japan Airlines (JAL) and All Nippon Airways (ANA) are forming strategic partnerships to secure a steady supply of fuel. The mandate also promotes investment throughout the entire value chain, covering aspects such as feedstock collection, blending infrastructure, airport fuel logistics, and ASTM-certified production technologies.
Additionally, Japan’s Green Transformation (GX) strategy, along with its commitment to achieving net-zero greenhouse gas emissions by 2050, provides long-term policy stability for SAF developers. Unlike conventional biofuel markets, aviation fuel requires stringent certification processes, making regulatory support crucial for speeding up commercialization efforts.
This policy is anticipated to drive investment in next-generation technologies such as Alcohol-to-Jet (ATJ) and Power-to-Liquid (PtL) fuels, reducing reliance on imported waste oils. As international airlines increasingly focus on minimizing lifecycle carbon emissions, Japan’s mandate positions domestic producers to engage in regional SAF supply chains across the Asia-Pacific region. Overall, the Japan Sustainable Aviation Fuel (SAF) Market is projected to transition from pilot-scale production to a commercially integrated ecosystem, where government policy acts as the primary catalyst for capacity expansion, long-term offtake agreements, and sustained investment in low-carbon aviation fuel technologies.
Limited domestic availability of sustainable feedstocks such as UCO, waste oils, and lignocellulosic biomass.
The limited domestic availability of sustainable feedstocks is a significant constraint on the Japan Sustainable Aviation Fuel (SAF) Market. Despite Japan’s ambitious aviation decarbonization targets, its resource base for feedstocks such as used cooking oil (UCO), animal fats, waste oils, and lignocellulosic biomass is relatively restricted. This limitation arises from geographic challenges, limited agricultural land, and competing demands from renewable diesel, biodiesel, and chemical industries.
Current industry estimates indicate that Japan generates approximately 450,000 to 500,000 metric tons of used cooking oil each year; however, much of this supply is already committed to food recycling, oleochemical production, animal feed, and biodiesel production. As a result, the surplus available for large-scale SAF production is quite limited. Additionally, Japan produces over 20 million tons of forestry residues annually, but the dispersed nature of this biomass across mountainous regions leads to increased costs for collection, transportation, and preprocessing, which diminishes its commercial viability.
The situation is further complicated by the expectation that multiple domestic SAF projects will come online before 2030, which will significantly increase feedstock demand beyond what is currently available domestically. To address this demand, producers are likely to turn to imported UCO and waste-based feedstocks from Southeast Asia and other regions, which may expose the supply chain to price volatility, logistical disruptions, and stringent sustainability certification requirements.
To reduce reliance on imported materials, companies are investing in advanced conversion technologies that can process municipal solid waste, algae, ethanol, and synthetic e-fuels derived from green hydrogen and captured carbon dioxide. Several Japanese refiners are also investigating long-term procurement agreements with international feedstock suppliers to enhance supply security. However, scaling these alternative pathways necessitates considerable capital investment and extended timelines for commercialization.
Thus, ensuring a diversified and resilient feedstock portfolio is crucial for the long-term competitiveness of the Japan Sustainable Aviation Fuel (SAF) Market. The availability of stable raw materials will directly impact production costs, plant utilization rates, and Japan's capacity to meet its target of a 10% SAF adoption rate for international flights by 2030.
Japan Sustainable Aviation Fuel (SAF) Market: Airport Refueling Infrastructure Assessment
The airport refueling infrastructure is emerging as a crucial component for the growth of Japan’s Sustainable Aviation Fuel (SAF) Market. The country’s aviation decarbonization strategy relies not just on the production of fuel but also on the efficiency of airport distribution networks. With over 95 commercial airports in operation, including five major international hubs Tokyo Haneda, Narita, Kansai International, Chubu Centrair, and Fukuoka these facilities handle approximately 75–80% of Japan's international passenger traffic and consume the bulk of aviation turbine fuel.
To achieve the government’s target of 10% SAF usage by 2030 for international departures, these airports need to establish dedicated SAF storage tanks, certified blending facilities, and upgraded hydrant fueling systems that comply with ASTM D7566 standards. Industry estimates suggest that supplying a 10% SAF blend could require nearly 1 million kiloliters of SAF annually by 2030, thereby exerting significant pressure on airport fuel logistics and storage infrastructure.
Existing petroleum terminals and coastal refinery networks are expected to play a vital role in moving SAF to major airports, helping to reduce capital expenditures by leveraging established pipeline and tanker infrastructures. Additionally, airports are investing in digital fuel traceability, inventory management, and lifecycle carbon accounting systems to satisfy sustainability reporting requirements set by airlines and regulators.
While international gateways are anticipated to be the first large-scale distribution centers for SAF, regional airports will gradually adopt the necessary infrastructure as domestic production increases. Therefore, the readiness of infrastructure regarding storage, blending, and fuel delivery systems will significantly affect the commercialization speed of the Japan Sustainable Aviation Fuel (SAF) Market. This preparedness will ensure reliable fuel availability, minimize supply bottlenecks, and support Japan's long-term net-zero aviation goals.
An analysis of plant mapping within the Japan Sustainable Aviation Fuel (SAF) Market reveals a refinery-led expansion predominantly driven by four major players converting existing crude infrastructure rather than establishing new greenfield sites. ENEOS, in collaboration with TotalEnergies and Mitsubishi Corporation, is advancing a facility at its Wakayama refinery in Arida City, which is expected to produce approximately 300,000 tons, or 400,000 kiloliters, of SAF annually starting from FY2028. This production will utilize used cooking oil, animal fat, and other waste-derived feedstocks.
Idemitsu Kosan is working on two subsidized units: a 250,000-kiloliter plant in Yamaguchi and a separate 100,000-kiloliter facility at its Chiba refinery near Tokyo. Meanwhile, Taiyo Oil is developing a 200,000-kiloliter project in Okinawa, with all these projects still in the design phase. Cosmo Energy has set itself apart as the first domestic producer to commence SAF production, having started output from used cooking oil at its Sakai refinery in western Japan in April. It aims to scale production to 300,000 kiloliters by 2030, combining domestic output with imports, and plans to establish a second site at Sakaide targeting bioethanol-based production by around 2029.
These collective initiatives, backed by government support of 340 billion yen (approximately $2.3 billion) in subsidies over five years, are aimed at meeting Japan's estimated SAF demand of 1.7 million kiloliters by 2030, according to the Ministry of Land, Infrastructure, Transport and Tourism. However, this plant mapping reveals a structural mismatch: the announced nameplate capacity of the five flagship projects aligns with the national demand figure only on paper, as most units are still pre-FID or in the early stages of construction. This situation indicates that actual physical output readiness will lag behind policy timelines, leading to a concentration of near-term supply in the coastal refining corridor of western Japan.
The Japan Sustainable Aviation Fuel (SAF) Market is anticipated to see the average selling price rise from USD 2,890 per ton in 2028 to USD 3,340 per ton by 2036, marking an increase of approximately 15.6% over the forecast period. Unlike traditional aviation fuel, SAF pricing is shaped by factors such as the cost of sustainable feedstocks, hydrogen production, carbon capture technologies, certification requirements, and a limited capacity for commercial production, rather than solely by crude oil prices.
In the early stages of commercialization, domestic production is predicted to face supply constraints while airline demand increases, driven by Japan's goal to achieve a 10% SAF adoption target for international flights by 2030. This demand will support stable pricing even as capacity gradually increases. Prices are expected to rise from USD 2,910 per ton in 2029 to USD 3,040 per ton in 2030, influenced by higher procurement costs for certified feedstocks, the expansion of refinery conversion projects, and rising operational expenses linked to blending and airport fuel logistics.
From 2031 onward, prices are projected to stabilize within the USD 3,080 to USD 3,340 per ton range, as commercial-scale HEFA facilities, Alcohol-to-Jet (ATJ), and Power-to-Liquid (PtL) projects enhance domestic supply while maintaining premium pricing for low-carbon aviation fuel. Feedstock economics, particularly for used cooking oil (UCO), waste oils, and renewable hydrogen, will play a crucial role in determining pricing, as these factors comprise a significant portion of production costs.
Additionally, the expenses associated with lifecycle carbon intensity certification, greenhouse gas accounting, and compliance with ASTM D7566 specifications will contribute to processing costs that do not apply to conventional jet fuel. Long-term offtake agreements between airlines and fuel producers are also expected to foster price stability by mitigating market volatility and bolstering investment certainty for new production facilities. As a result, the Japan SAF Market is poised to maintain a premium pricing structure throughout the forecast period, driven by strong regulatory demand, limited availability of feedstocks, ongoing infrastructure investments, and continuous advancements in technology aimed at enhancing production efficiency while ensuring the economic viability of sustainable aviation fuels.
