Canada Aims to Cut Japan's 72% Reliance on Chinese Rare Earths

Key Takeaways 82% confidence

• China halted shipments of dysprosium, terbium and yttrium to Japan starting in December 2025, restrictions officially aimed at military end-users that also disrupted civilian supply.
• Despite 15 years of diversification since a 2010 export restriction tied to the Senkaku/Diaoyu Islands dispute, China still supplied 72.5% of Japan's rare earth imports in the first half of 2026, down only slightly from 75% in 2025, according to JOGMEC data.
• Canada holds the world's 10th-largest commercially extractable rare earth reserves but produced zero tonnes in both 2024 and 2025; of 23 active Canadian rare earth projects, only three have reached the processing stage.
• Prime Minister Mark Carney and Japanese Prime Minister Takaichi Sanae signed a Comprehensive Strategic Partnership in Tokyo on March 6, 2026, elevating bilateral critical minerals cooperation and exploring joint stockpiling.
• Canada's rare earth exports to Japan grew from C$0.018 million in 2020 to C$0.5 million in 2025, still a tiny fraction of trade even as Japan accounted for 19% of Canada's total rare earth exports that year.
• Real commercial deals are emerging: Rio Tinto's Sorel-Tracy plant in Quebec became North America's first scandium oxide producer in 2022, Ucore Rare Metals and Sumitomo Corporation of Americas announced a rare earth supply collaboration on June 10, 2026, and KAP Minerals signed a rare earth and phosphate offtake-focused agreement with Hanwa Co., Ltd. on May 14, 2026.

China still supplies about 72% of Japan's rare earth imports, even after a 2025 export halt. Canada, sitting on major reserves but zero production, is emerging as a potential partner.

Analysis 78% confidence

Fifteen years is a long time to try to fix a supply-chain problem and still be mostly stuck with it. That is effectively where Japan sits with rare earth elements (REEs), a group of 17 metals used in electric-vehicle motors, wind turbines, semiconductors and precision-guided weapons, few of which have a good substitute at scale. The original push to diversify traces back to 2010, when a collision between a Chinese fishing trawler and the Japanese Coast Guard near the disputed Senkaku/Diaoyu Islands led Beijing to restrict rare earth exports to Japan. China never acknowledged a formal embargo, but the disruption was real enough that Tokyo responded with new stockpiles, new supplier relationships and public financing for non-Chinese processing capacity through JOGMEC, the state-run Japan Organization for Metals and Energy Security. Measured by where Japan's rare earths actually come from today, that 15-year effort has bought less ground than the scale of the response would suggest: China supplied 75% of Japan's REE imports in 2025 and 72.5% in the first half of 2026, according to JOGMEC's own figures. Vietnam is a distant second at 12.4%, and even that relationship covers only around 40% of the separation technology needed to turn raw ore into usable metal, the step where a supply chain becomes genuinely independent of China rather than just diversified on paper.

December 2025 made that gap concrete again. China halted shipments of dysprosium, terbium and yttrium, three heavy rare earths used in high-performance magnets, with the curbs formally targeting military end-users but bleeding into ordinary commercial supply regardless. Japan responded the way it has before: drawing down its own stockpiles and pushing harder on alternative sourcing. Canada ranks 10th globally for commercially extractable REE reserves, more than enough, in principle, to matter to a country like Japan. In practice, it produced none in 2024 or 2025. Of 23 active Canadian rare earth projects tracked by the Asia Pacific Foundation of Canada, only three have advanced as far as processing, the stage where a deposit in the ground actually becomes something a magnet maker can use. That gap between reserves and refined output is the same one China spent decades closing at home, and it is the specific gap Japan's strategy has learned to target directly rather than just funding exploration and hoping mines eventually get built.

Canada is only one front in that strategy. Japan revised its offtake agreement with Australia's Lynas Rare Earths in March 2026, reserving 75% of Lynas's heavy rare earth oxide output for Japanese industry and locking in a $110-per-kilogram floor price for 5,000 tonnes a year of neodymium-praseodymium through 2038. At home, Tokyo is backing Shin-Etsu Chemical's first new domestic rare earth refinery since 2008 with a ¥17.5 billion government subsidy toward a plant focused on dysprosium, terbium and yttrium. Set against those two moves, Canada is a newer and so far smaller piece of the same diversification playbook, not its centerpiece.

What Ottawa and Tokyo have built for Canada specifically is governance scaffolding that predates this year's headline announcement. A Canada-Japan Sectoral Working Group on Critical Minerals was set up in 2020, followed by a Canada-Japan Battery Supply Chain Memorandum in 2023 and a separate British Columbia renewal of its own critical-minerals memorandum with JOGMEC the same year. What changed in March 2026 was scale and ambition: Carney and Takaichi's Comprehensive Strategic Partnership, spanning defence, energy, trade and technology, commits both governments to securing reliable supplies, enabling value-added processing and supporting diversified manufacturing against market distortions and export restrictions, with an explicit line on exploring joint critical minerals stockpiling. That is a broader mandate than any prior bilateral document on the subject, though a roadmap is not itself a mine or a refinery.

Underneath the government framework, a specific commercial pattern is starting to repeat. Japanese trading houses have long combined patient capital, offtake agreements and government-backed financing to secure resources abroad, and that pattern is now showing up in Canadian rare earths specifically rather than only the base-metals and iron-ore sectors where it has long been standard practice. Rio Tinto's demonstration plant in Sorel-Tracy, Quebec became North America's first scandium oxide producer in 2022 and is now being expanded with backing from Canada's federal Canada Growth Fund. Ucore Rare Metals, a Nova Scotia-based rare earth separation company running a demonstration facility in Kingston, Ontario, announced a strategic collaboration with Sumitomo Corporation of Americas on June 10, 2026 to source rare earth feedstock and distribute separated heavy rare earth products to Japanese customers. In Ontario, KAP Minerals, developing a former phosphate mine near Kapuskasing whose tailings are estimated to hold more than 100,000 tonnes of rare earth minerals alongside scandium, niobium and tantalum, signed a long-term offtake-focused memorandum with the Japanese trading company Hanwa Co., Ltd. on May 14, 2026. Two more Canadian facilities, a rare earth recycling demonstration plant near St. Hubert, Quebec and a Saskatchewan Research Council processing facility, are both scheduled for completion later in 2026. None of this guarantees results: JOGMEC committed C$2.7 million for a 50% stake in Midland Exploration's Ytterby project in the same year the Senkaku dispute began, and that agreement was terminated in 2017 after the project never advanced past exploration. Canadian rare earth exports to Japan, meanwhile, grew from C$0.018 million in 2020 to C$0.5 million in 2025, real growth, but still a rounding error next to the scale of Japan's dependence on China.

Why This Matters 68% confidence

For a market that already prices in some scarcity risk around rare earth magnets used in EVs, wind turbines and defense electronics, the practical question isn't whether Canada and Japan want a deal, it's whether financing and construction schedules move fast enough to matter before the next Chinese export restriction lands. India and other import-dependent economies face the same structural exposure to Chinese-controlled processing that Japan is trying to work around, so the tools being tested here, patient financing, offtake agreements paired with demonstration-scale processing plants, and government-to-government roadmaps, amount to a live test of whether any of that actually shortens the distance between announced reserves and usable metal.

Price Impact

This is a supply-chain and policy story rather than a near-term price mover. Canada still produced zero rare earths in 2025 and its exports to Japan remain a rounding error at C$0.5 million, so the direct market effect of this partnership today is minimal. The more significant near-term price driver for heavy rare earths remains China's own December 2025 export halt on dysprosium, terbium and yttrium; the Canada-Japan cooperation is a multi-year bet on reducing that exposure, not a substitute for it, and its effect on supply won't show up meaningfully until facilities now under construction reach commercial production.

Fundamental Analysis

Demand Drivers 75% confidence

Rare earth elements are used in electric-vehicle motors, wind turbines, semiconductors and precision-guided weapons, end uses with few substitutes at scale, which is why Japanese manufacturers and the Japanese government have treated reliable, non-Chinese supply as a strategic priority rather than a simple cost question.

Supply Drivers 78% confidence

Canada ranks 10th globally for commercially extractable rare earth reserves but produced none in 2024 or 2025. Of 23 active Canadian rare earth projects, only three have reached the processing stage, and new capacity is concentrated in a handful of facilities: Rio Tinto's Sorel-Tracy scandium plant, producing since 2022, plus a St. Hubert recycling demonstration plant and a Saskatchewan Research Council processing facility, both due for completion later in 2026.

Inventory Drivers 65% confidence

Japan's National Stockpiling System has extended its coverage horizon to 180 days for high-risk minerals, and the March 2026 Comprehensive Strategic Partnership commits Canada and Japan to exploring joint critical minerals stockpiling, alongside Japan's separate drawdown of existing stockpiles after China's December 2025 export halt on dysprosium, terbium and yttrium.

Government Policies 82% confidence

The Comprehensive Strategic Partnership Prime Minister Mark Carney and Japanese Prime Minister Takaichi Sanae signed in Tokyo on March 6, 2026 builds on a Canada-Japan Sectoral Working Group on Critical Minerals from 2020 and a Canada-Japan Battery Supply Chain Memorandum from 2023. Canada's own critical minerals list, which spans 34 minerals including copper, lithium, gallium, potash and rare earths, and Japan's 2022 Economic Security Promotion Act both provide the domestic legal basis for this cooperation.

Geopolitical Risks 78% confidence

China still supplied 72.5% of Japan's rare earth imports in the first half of 2026 despite 15 years of Japanese diversification efforts that began after the 2010 dispute over the Senkaku/Diaoyu Islands. China's December 2025 halt of dysprosium, terbium and yttrium shipments, formally aimed at military end-users, showed that dependency remains an active vulnerability rather than a resolved one.

Mining Production 76% confidence

Canada produced zero rare earths in both 2024 and 2025 despite holding the world's 10th-largest commercially extractable reserves. A prior Japanese-backed attempt to develop a Canadian rare earth deposit, JOGMEC's 2010 investment in Midland Exploration's Ytterby project, was abandoned in 2017 after the project failed to advance past exploration.

Refinery Output 74% confidence

Rio Tinto's Sorel-Tracy plant in Quebec became North America's first scandium oxide producer in 2022 and is being expanded with backing from Canada's Canada Growth Fund. Ucore Rare Metals operates a rare earth separation demonstration facility in Kingston, Ontario using its RapidSX technology, and announced a distribution collaboration with Sumitomo Corporation of Americas on June 10, 2026 aimed partly at Japanese customers.

Market Sentiment

Alternative Scenarios 62% confidence

• If the St. Hubert and Saskatchewan Research Council facilities reach completion on schedule in late 2026, and the Ucore-Sumitomo and KAP Minerals-Hanwa agreements progress to firm offtake volumes, Canada could begin building a genuine, if still small, alternative rare earth supply chain for Japan over the next few years.
• If financing or permitting delays stall these projects the way they did at Ytterby, the Comprehensive Strategic Partnership could end up producing more governance documents than actual tonnes, leaving Japan's dependence on China largely unchanged.
• A further Chinese export restriction, rather than the pace of Canadian project development, could end up being the more immediate factor shaping how much urgency Japan and Canada bring to these deals.

Who Benefits, Who Loses

Investor Watchlist 74% confidence

Educational items to monitor — not investment advice.

• Whether the St. Hubert rare earth recycling demonstration plant and the Saskatchewan Research Council processing facility reach completion on their stated 2026 timelines
• Progress on the Ucore Rare Metals-Sumitomo Corporation of Americas collaboration signed June 10, 2026, including whether it produces firm offtake volumes
• Whether the KAP Minerals-Hanwa Co. memorandum signed May 14, 2026 advances into a binding offtake agreement for the Kapuskasing project
• Any further Chinese export restrictions on rare earths, following December 2025's halt on dysprosium, terbium and yttrium shipments to Japan
• Whether Canada and Japan's explored joint critical minerals stockpiling moves from the Comprehensive Strategic Partnership's roadmap into an actual funded mechanism

Price Risks 68% confidence

• Continued Chinese dominance of rare earth processing, still 72.5% of Japan's import supply in the first half of 2026, leaves prices for dysprosium, terbium, yttrium and other heavy rare earths exposed to further Chinese export restrictions like December 2025's.
• If Canadian processing capacity comes online on schedule in late 2026, even the small volumes involved could begin to affect pricing for specific rare earths such as scandium, where Rio Tinto's Sorel-Tracy plant already represents the entirety of North American supply.

Historical Comparison

2010 Senkaku/Diaoyu rare earth export restriction: Japan's original push to diversify away from Chinese rare earths began after this dispute; 15 years later, China still supplied 72.5% of Japan's rare earth imports in the first half of 2026, showing how difficult that diversification has been to achieve in practice.
2010-2017 JOGMEC-Ytterby investment: Japan's most direct prior attempt to develop a Canadian rare earth deposit was abandoned after seven years without reaching production, a precedent the current wave of Canada-Japan agreements will need to avoid repeating.
