【1】🛢️ Japan gives order to prepare for release of oil reserves [03/10 Nikkei Asia]
Japan’s METI has instructed national oil reserve sites to prepare for potential release as Iran’s closure of the Strait of Hormuz threatens over 90% of Japan’s crude imports. Japan holds 254 days of combined public-private stockpiles. G7 finance ministers signaled readiness for coordinated release, though Tokyo may act unilaterally if domestic supply tightens. WTI briefly topped $110/bbl.
【2】⚡ Japan’s Middle East energy dependency — and how it mitigates shocks [03/04 Reuters]
Japan sources ~95% of oil and 11% of LNG from the Middle East, with ~70% and 6% respectively transiting the Strait of Hormuz. Combined public-private oil reserves cover 254 days of consumption, including Saudi Aramco tanks in Okinawa that grant Japan preferential emergency access. LNG stockpiles would cover 44 weeks if Hormuz disruption persists; if all imports halted, roughly three weeks remain. JERA secures at least one monthly emergency cargo as the government’s designated agent, while fuel subsidies stay active amid yen weakness.
【3】🌏 Fifteen years after Fukushima, Japan faces an energy dilemma [03/02 The Economist]
Japan’s energy policy faces a triple contradiction: a stalled renewables buildout, an aging nuclear fleet, and entrenched fossil fuel dependence. New wind and solar installations hit a 17-year low in 2024, as subsidies are cut and political opposition to “foreign-made solar panels” grows. Reaching the 20% nuclear target by 2040 requires nearly all 21 eligible reactors online—yet most face retirement in the 2040s–50s. Without technological breakthroughs in fusion, hydrogen, or geothermal, fossil fuels remain the default gap-filler.
【4】📊 [Report] “What’s GX-ETS?” - Japan’s GX-ETS Launches in April—But Structural Weaknesses May Undermine Its Climate Impact [03/05 Climate Integrate]
Climate Integrate’s new report on Japan’s GX-ETS—launching April 2026—identifies critical structural weaknesses that may limit its real-world impact. The mandatory Phase 2 covers 300–400 companies representing ~60% of Japan’s GHG emissions, but operates with no aggregate emission cap, free allocation, low price floors/ceilings, and a 10% offset allowance—all combining to create weak reduction incentives. Power sector paid allocation is deferred to 2033. Simulations suggest that under current requirements, actual emissions could exceed companies’ own voluntary commitments. Whether the system can deliver Japan’s NDC targets for 2030 and 2035 remains structurally unclear.
【5】☢️ As Fukushima memories fade, Japan embraces a nuclear-powered future [03/09 Reuters]
Fifteen years after Fukushima, Japan is accelerating its nuclear return under pro-nuclear PM Takaichi, buoyed by energy security concerns and surging AI data center demand. Public support for restarts has climbed to 51%—up from 28% in 2013—with youth aged 18–29 the most supportive at 66%. The restart of Kashiwazaki-Kariwa marked a symbolic milestone, while Mitsubishi Heavy Industries projects record nuclear unit sales of ¥400B next year. Yet talent supply remains a critical bottleneck: only 177 students enrolled in nuclear programs in 2024, well below the 317 recorded before the disaster.
【6】🏭 Japan’s nuclear comeback slow, steady and seen as necessary [03/06 The Japan Times]
Japan’s nuclear revival is progressing slowly but steadily, with Kashiwazaki-Kariwa Unit 6—TEPCO’s first restart since Fukushima—set for commercial operation on March 18. Nuclear currently supplies 8.5% of electricity; the government targets 20% by FY2040, but the Renewable Energy Institute estimates this requires restarting 32 of 33 operable reactors plus three new builds. Electricity rates in TEPCO’s service area run roughly 30% higher than in Kansai, where more reactors operate. Experts stress nuclear, renewables, and thermal power must coexist, not compete.
【7】🤖 Japan’s Fukushima Clean-Up Offers a Blueprint for Nuclear Recovery [03/09 Bloomberg]
TEPCO plans to deploy a purpose-built 22-meter robotic arm as early as this summer to extract samples of approximately 880 tons of fuel debris lodged at the bottom of Fukushima’s three damaged reactors. The results will inform full-scale removal, which won’t begin until 2037, with the entire decommissioning process—costing hundreds of billions of dollars—expected to last until mid-century. The IAEA’s director general sees Fukushima as a potential global blueprint: of 200+ reactors already closed worldwide, only 11 have been fully decommissioned, and a further 200 are set to retire within two decades.
【8】💨 Denmark’s Vestas to build wind turbines in Japan [03/09 Nikkei Asia]
Vestas, the world’s largest offshore wind turbine maker, will establish a nacelle assembly plant in Japan by FY2029—with full domestic production capability by FY2039—under an MOU with METI. Kitakyushu and Muroran are candidate sites, with investment expected in the tens of billions of yen. The move aims to cut transport costs and counter yen weakness that have made imported turbines prohibitively expensive. Japan is also positioned as an export hub targeting Asian markets including Vietnam, the Philippines, and Australia.
【9】🏗️ Japan’s playbook on raw materials security is worth taking global [03/10 Financial Times]
Japan’s model of pairing trading houses with state agencies like JOGMEC is attracting European attention as Germany eyes a Japanese-style approach to critical minerals security. Japan cut its reliance on Chinese critical minerals from ~90% to ~60% after Beijing’s 2010 export halt. The model—combining commodity ownership, data, and long-term public financing—is now seen as a global blueprint, with Mitsubishi Corp’s $600M Arizona copper mine investment a recent example. However, the FT notes a structural flaw: trading houses’ extensive fossil fuel holdings reduce their incentive to accelerate the renewables transition—a tension that Mitsubishi, Mitsui, and Itochu will face increasing scrutiny over from ESG-focused investors.
【10】⚗️ Japan’s Sumitomo invests in US fusion technology startup Shine [03/10 Nikkei Asia]
Sumitomo Corp. has invested in U.S. fusion startup Shine Technologies, which produces lutetium-177 for cancer treatment and other fusion-derived applications. Sumitomo will distribute the isotope across Asian markets via its pharma affiliate Summit Pharmaceuticals, while exploring collaboration in radioactive waste recycling and fusion power generation. Founded in 2005 and having raised over $1 billion, Shine represents Sumitomo’s third fusion-related investment, following TAE Technologies and Tokamak Energy.
【11】🏙️ Fukushima’s corporate comeback 15 years after Japan’s worst disaster [03/11 Nikkei Asia]
Fifteen years after Fukushima, new businesses—including a hydrogen startup and a winery—are emerging in affected towns, but over 50% of displaced residents from Futaba, Okuma, and Namie say they will never return. A Fukushima University expert warns of a structural gap between infrastructure restoration and genuine community recovery. For businesses entering the region, the chronic shortage of working-age population poses a fundamental operational risk that subsidies alone cannot offset.
【12】🎬 ‘Fukushima: A Nuclear Nightmare’ Review: A Wave of Disaster on HBO [03/05 The Wall Street Journal]
HBO’s “Fukushima: A Nuclear Nightmare” arrives on the disaster’s 15th anniversary as a gripping nonfiction thriller, pairing raw archival footage with testimonies from plant workers who stayed on-site knowing they might not survive. Director James Jones—known for “Chernobyl: The Lost Tapes”—goes beyond disaster chronology to examine Japanese corporate culture, the institutional shame carried by TEPCO employees, and Japan’s days-long reluctance to share critical information with U.S. responders. For deeper immersion, pair it with Netflix’s dramatized series “The Days” (netflix.com/watch/81234485), which reconstructs the crisis hour by hour from inside the plant.
