Lynas Japan rare earth supply is now secured under a landmark 12-year agreement signed 10 March 2026, committing Lynas Rare Earths (ASX: LYC) to supply 5,000 tonnes of neodymium-praseodymium (NdPr) per annum at a US$110/kg floor price, alongside 50–75% of all heavy rare earth oxides it produces, through to 2038.
The counterparty is Japan Australia Rare Earths B.V. (JARE), a special purpose vehicle established by the Japan Organization for Metals and Energy Security (JOGMEC) and trading house Sojitz Corporation. The agreement updates a 15-year prior partnership and represents the most substantive bilateral rare earth supply commitment outside China currently in force.
Lynas Japan Rare Earth Agreement: Full Terms
The updated agreement covers both light and heavy rare earth oxides across two distinct tranches. NdPr offtake is structured with a firm commitment and an extended availability window for Japanese industry buyers:
| Term | Detail |
|---|---|
| Agreement duration | 12 years — to 2038 |
| NdPr firm offtake | 5,000 t/annum at US$110/kg floor |
| NdPr availability (Japanese industry) | Up to 7,200 t/annum, subject to no opportunity loss to Lynas |
| Upside sharing | When NdPr exceeds US$150/kg — capped at US$10m/annum |
| HRE firm offtake | 50% of all HRE oxides produced by Lynas |
| HRE availability (Japanese industry) | Up to 75% of all HRE oxides Lynas produces |
| HRE pricing basis | No opportunity loss to Lynas; volumes and prices agreed by Lynas, JARE, and each customer |
The upside-sharing mechanism reflects Japan’s strategic interest in price stability rather than pure cost minimisation. At current NdPr benchmark levels of approximately US$126/kg domestic China (SMM, April 2026), the floor provides downside protection without binding Japanese buyers to above-market rates at scale.
Why Japan Is Urgently Securing Supply
China’s rare earth export controls introduced in January 2026 have disrupted flows to Japan more severely than any other major consumer economy. Rare earth magnet volumes exported from China to Japan fell 17% month-on-month in March 2026 to 184 tonnes — a nine-month low. Intermediate materials including oxides fell nearly 90% in the same month.
The controls were imposed following Japanese Prime Minister Takaichi’s remarks on Taiwan and represent the sharpest application of rare earth trade leverage since China’s 2010 embargo against Japan. Unlike that episode, the 2026 controls apply across a broader product range including oxides, alloys, and magnets — closing the workarounds Japanese buyers previously used.
Japan’s particular vulnerability lies in dysprosium and terbium — heavy rare earth elements used in high-performance NdFeB magnets for EV motors and industrial applications. China controls over 90% of global heavy rare earth separation capacity. The JARE agreement’s HRE provisions — 50–75% of Lynas output — directly target this exposure. Lynas’s Q3 FY26 production of 8 tonnes of dysprosium and terbium combined is small relative to Japan’s requirements, but the agreement establishes priority access to Western-sourced supply as Lynas scales its Malaysia HRE separation facility.
What the JARE MOU Adds
Alongside the binding supply agreement, Lynas and JARE signed a non-binding memorandum of understanding on 13 March 2026 covering cooperation across the rare earths value chain. The focus is mineral exploration of REE and adjacent minerals, specifically supporting Lynas’s stated growth pillar of adding resource and scale at Mt Weld in Western Australia — currently one of the highest-grade rare earth carbonatites globally.
The MOU scope includes development of the Mt Weld ore body and identification of complementary feedstock sources. Definitive agreements are subject to negotiation. If converted, this would extend the Japan-Australia rare earth partnership into upstream resource development — a qualitatively different level of strategic alignment than a pure offtake arrangement.
Implications for HRE Pricing
The JARE agreement’s HRE commitment has direct implications for dysprosium and terbium availability to non-Japanese buyers. With up to 75% of Lynas’s heavy rare earth oxide production committed to Japanese industry, third-party access to Lynas-sourced HRE — already limited by the company’s production scale — is materially constrained.
Lynas produced 8 tonnes of dysprosium and terbium combined in Q3 FY26, with production lower than expected due to scheduling; work-in-progress material is expected to be processed in Q4. The Malaysia HRE separation facility expansion is underway and samarium oxide production commenced in March 2026, indicating broader HRE capability is being built out. However, the scale gap between Lynas’s current HRE output and China’s remains significant — the JARE agreement absorbs most of the non-Chinese supply that exists today.
Two developments to watch: progress toward binding definitive agreements under the MOU, and Lynas’s Q4 FY26 HRE production figures, which will establish whether the scheduling-related Q3 shortfall has been recovered. Lynas reported Q3 FY26 group revenue of A$265 million, a 115% year-on-year increase, reflecting the scale of price and volume movement underway across the Lynas business.

What is the Lynas Japan rare earth supply agreement?
Lynas Rare Earths (ASX: LYC) signed a 12-year agreement on 10 March 2026 with Japan Australia Rare Earths B.V. (JARE), committing to supply 5,000 tonnes of NdPr per annum at a US$110/kg floor price, plus 50–75% of all heavy rare earth oxides it produces, through to 2038. The agreement updates a prior 15-year partnership between Lynas, JOGMEC, and Sojitz Corporation.
Who is JARE and why does it matter for rare earth supply?
JARE — Japan Australia Rare Earths B.V. — is a special purpose company established by JOGMEC (Japan’s national resource security agency) and Sojitz Corporation. It channels Japanese government and private sector demand for rare earths secured outside China. The JARE structure allows Japan to aggregate offtake from Lynas and allocate volumes across multiple Japanese industry buyers, providing both price stability and supply continuity.
What is the NdPr floor price in the Lynas JARE agreement?
The agreement sets a floor price of US$110/kg for NdPr firm offtake of 5,000 tonnes per annum. An upside-sharing mechanism activates when NdPr prices exceed US$150/kg, capped at US$10 million per annum. The SMM domestic China NdPr benchmark stood at approximately US$126/kg in April 2026.
How does the JARE agreement affect dysprosium and terbium supply?
The agreement commits up to 75% of all Lynas heavy rare earth oxide production — including dysprosium and terbium — to Japanese industry. Lynas is currently the only commercial producer of heavy rare earth oxides outside China at scale. Committing the majority of this output to JARE materially limits HRE availability to non-Japanese buyers in the Western market.
Why is Japan securing rare earth supply outside China?
China’s January 2026 export controls caused rare earth magnet volumes to Japan to fall 17% month-on-month in March 2026, with oxide and intermediate material shipments down nearly 90%. Japan remains heavily dependent on China for heavy rare earths used in high-performance magnets for EV motors and defence applications. The JARE agreement is part of Japan’s long-running strategy to build non-Chinese supply lines, accelerated by the 2026 export control escalation.
