Japan’s hydrogen bet looks more strategic than green
Japan’s hydrogen push may not be just about decarbonisation but also for strategic insurance against energy uncertainty.
Over the past few years, Japan has repeatedly deployed direct subsidies to shield households from various costs. However, the recent US-Iran conflict served as a signal to investors that there is a deeper problem.
Japan has a habit of repeating patterns, and the current war revived this. As global oil supply turned unstable, the country fell back to its usual toolkit of subsidies, stockpiles, diplomatic reassurances, and last-minute efforts to forge new energy alliances and secure alternative supplies. One could even surmise Japan stockpiling oil in 1973 may be due to its vulnerability to Middle Eastern instability.
Japan relies on the Middle East for roughly 95 per cent of its crude oil and 11 per cent of its liquefied natural gas (LNG) imports, with shipments often passing through the Strait of Hormuz. To compare, Korea’s energy self-sufficiency rate is at 22.1 per cent while Japan’s remains at 16.3 per cent.
As the conflict lingers, it exposes Japan to yet another energy security threat, and it is evident in household sentiment. An August 2026 survey shows that 87.5 per cent of households expect prices to rise over the next year, still above the readings before the global oil supply shock. Graph 1 further shows that 45 per cent expect prices to rise by 5 per cent or more. The Consumer Confidence Index also showed monthly drops in March-April, indicating dimming sentiment, before some recovery seen in May-August. This shows Japan’s energy pains is beyond supply routes and import bills: it also demonstrates how quickly external shocks creep into domestic perceptions.
Japan spent years trying to cushion households from this pain. The government enacted another round of utility and gas subsidies starting July under a JPY 3.11 trillion (USD 19 billion) supplementary budget, fully financed through new government bonds.
Old, expensive problem
The deeper issue is the cost of dependency. In 2023, Japan spent about JPY 26 trillion (USD 160 billion) importing crude oil and natural gas, largely funded by export revenues on automobiles and semiconductor manufacturing equipment. Major disruptions in the fuel markets not only raise utility bills but also lead to large leakages of national income abroad. This forces the Japanese government to dig deeper into its coffers to shield households and firms from the growing fuel import costs.
Japan is once again relying on subsidies and relaxing some rules to make the short-run energy system more flexible. Recently, restrictions were relaxed on low-efficiency coal-fired plants to conserve LNG. Additionally, refiners have been looking to the US and Latin America for substitute crude supplies despite the longer and more expensive logistics costs.
These policies suggest an energy system still buying time rather than solving its long-term vulnerability. Without any lasting clear solution, energy insecurity will remain a recurring problem.
Hydrogen as insurance
The power instability may intensify Japan’s search for alternative sources to add to its energy mix. Its “hydrogen society” push may grow stronger despite its high cost and relative underdevelopment.
However, Japan is not backing hydrogen power only because it wants to decarbonise; rather, it wants more options for safety, energy security, economic efficiency, and the environment. As such, it aims for a public-private push worth about JPY 15 trillion (USD 92 billion) over 15 years to build supply chains, achieve scale, and attract both domestic and foreign players.
Graph 2 shows that Japan’s hydrogen ambitions are not coming from nowhere as it is the leading source of hydrogen and fuel-cell patents through most of the past decade. However, other countries are catching up: Korea and China have narrowed the gap in recent years while Germany remains a serious player. That makes hydrogen a more urgent strategic bet for Japan. The issue is whether it can turn that capability into wider commercial deployment before rivals beat it to the punch.
Japan has technological depth, but commercial adoption remains modest. Though it has pushed hydrogen power for years, actual uptake has been much weaker than expected. For instance, the 5th Strategic Energy Plan aimed for 5.3 million, or about 10 per cent, of households to install ENE-FARM residential fuel-cells by 2030. The succeeding plan moved the target lower to 3 million units. Yet, fewer than 500,000 household fuel-cell units had been installed as of March 2023 and a little over 560,000 by 2025.
This underperformance is exactly why the latest energy shock matters. It does not suddenly make hydrogen cheap, nor does it turn fuel cells into an immediate answer to this recent energy anxiety. It may, however, force Japan to take the financing and deployment problem more seriously. Policy-wise, Japan’s updated Basic Hydrogen Strategy still targets hydrogen usage of roughly 3 million tonnes annually by 2030, 12 million by 2040, and 20 million by 2050. Meanwhile, the 2025 Strategic Energy Plan indicates government provisions of around JPY 3 trillion (USD 19 billion) in price-gap support under the Hydrogen Society Promotion Act to kick off large-scale projects.
There is also a real ecosystem forming around the hydrogen push with several public-private partnerships spanning transport, production, storage, and end-use, from hydrogen carrier work to collaborations involving foreign firms entering Japan’s market.
Though alternative energy projects are still in initial stages, they show Japan’s commitment towards domestic energy security. Importantly, investors should not see hydrogen as merely experimental but as a potential scaling market.
Not everyone is convinced that hydrogen is the right answer. Some critics argue that Japan may be overprioritising hydrogen and ammonia over more direct decarbonisation routes, which points to a real tension in Japanese energy policy. Last year, major refiners scaled back some hydrogen and ammonia ambitions as costs rose and energy security concerns pushed them back toward more conventional fuels. That does not invalidate Japan’s hydrogen strategy, but it does show future-proofing efforts while still leaning on the old energy mix to survive the present.
The point is not that hydrogen will rescue Japan from the latest Middle East crisis – it will not. Rather, every such crisis makes the search for alternatives harder to ignore. Japan stands too dependent on imported fossil fuels, too exposed to shipping chokepoints, and too quick to hand out subsidies whenever energy costs jump. Investors should see Japan’s hydrogen path less as green idealism and more as a long-term hedge against external vulnerabilities.
For investors, the more near-term opportunity lies with firms already building around hydrogen energy systems. The strategy still faces obvious risks, but after the latest shock, it is taking greater prominence in Japan’s quest for a more energy-secure future.
