Japan-France Roadmap on Cooperation in Critical Minerals (Takaichi-Macron Tokyo Summit)

Mechanism

The roadmap is a non-binding bilateral instrument elevating economic security to the centre of the Japan-France "exceptional partnership". Its operational core is the Caremag project — a rare-earths refining facility in southern France that, once online in late 2026, will be the largest heavy-REE refining operation in the EU and one of the few outside China. JOGMEC (Japan's state-backed metals/energy security agency) and Iwatani Corporation provide the Japanese side of the investment + offtake architecture, while the French government anchors the European side through industrial policy levers tied to the EU Critical Raw Materials Act.

The 20%-of-Japan's-demand target for dysprosium and terbium is structurally significant because:

• China processes ~85% of global REE and produces ~95% of

dysprosium / terbium, which are used in NdFeB sintered permanent magnets that retain coercivity at elevated temperatures (EV traction motors, offshore-wind direct-drive generators, defence guidance systems).

• Heavy REE supply is far more concentrated than light REE —

there is essentially no commercial heavy-REE refining outside China today, so a single mid-scale project in France meaningfully shifts the diversification math for Japan.

• The Caremag offtake model echoes the JOGMEC equity-and-loan

template already used for Lynas, Iluka, and the Australia REE cluster, and now extends it into the EU.

Beyond minerals, the roadmap operationalises four parallel high-level dialogue tracks: dual-use AI (with a Japan-hosted AI Summit referenced in the summit communiqué), quantum, space (including debris mitigation and continued private- sector cooperation), and cybersecurity, plus a joint startups-and-innovation declaration aimed at industrial competitiveness.

Severity rationale (3)

• Head-of-state declaration with named flagship project (Caremag)

rather than aspirational language.

• Structurally first Japan-EU-bilateral REE refining anchor; not

the first JP critical-minerals MoU (US, Australia, Vietnam, Uzbekistan precede), but the first to embed an actual EU refining facility into Japan's supply chain.

• Non-binding, so no immediate trade or financial restriction;

severity 3 (qual) reflects strategic significance without enforceable parameters.

Downstream implications

• Heavy-REE refining geography: Caremag becomes the

reference EU heavy-REE refining node, complementing Solvay La Rochelle (light REE) and reducing EU exposure to a single Chinese chokepoint.

• Japan supply diversification math: with ~20% of

dysprosium/terbium demand covered via France, Japan stacks this on top of its US (Trump-Takaichi 2025-10-27 framework), Australia (Lynas Kalgoorlie), and Vietnam (Lai Chau / Dong Pao) sources. The portfolio is now genuinely four-way.

• EU-Japan-Canada triangulation: ORF and other analysts

have framed Caremag as one node in a Canada-Japan-France triangle rewiring REE flows; expect follow-on Japan-Canada refining deals.

• EV / offshore-wind input cost: to the extent Caremag

meets cost parity, Japanese EV-motor and turbine OEMs gain a non-China-routed dysprosium-terbium option, lowering tail risk on Chinese export-licence delays.

• G7 critical-minerals diplomacy cohort: sits alongside

US-Japan (2025-10-27), US-Australia (2025-10-20), US-Malaysia (2025-10-26), US-Saudi (2025-11-18), US-Uzbekistan (2026-02-04), India-Brazil (2026-02-21), EU-US (2026-04-24) as the 2025-2026 head-of-state critical-minerals diplomacy wave.

Open questions

• Canonical Joint Declaration / Roadmap PDF: MOFA returned 403

to direct fetch from this VPS UA; the canonical text URL on mofa.go.jp/files/ has not yet been located. Future wake should retry from a different fetcher.

• Élysée counterpart joint declaration page not located via

English search; a French-language fetch may surface a parallel canonical FR-side declaration.

• Caremag financing breakdown (JOGMEC equity vs. Iwatani

offtake vs. French state aid via France 2030 / the EU CRMA Strategic Project pipeline) not yet disclosed publicly.

• Whether the roadmap embeds binding offtake percentages or is

purely a coordination framework — the public summary language is "support for raw material supplies" rather than contracted volumes.
