Published 2026-08-13
Summary: The United States and Japan are discussing a plan to pursue a deep-sea mining project near Minamitorishima/Minamitori Island with the aim of extracting rare earths and challenging China’s dominance of the global rare earths supply chain.
What We Know
- The initiative involves collaborative deep-sea mining related to rare earths near Minamitorishima / Minamitori Island.
- The objective is to challenge China’s dominance in rare earths, a key component of the global supply chain.
- Some sources describe the project as aiming for depths around 6,000 meters, signaling a very deep-sea operation.
- Reports indicate coordination between the United States and Japan, with involvement from corporate actors in Japan and U.S. partners; however, specific company names and progress status vary across sources.
- The plan has been described as a potential pathway to diversify supply and reduce dependence on China for rare earths.
What’s Still Unclear
- Whether the plan has moved from proposal to active mining or is still at the discussion stage.
- Exact permitting, regulatory, and environmental frameworks governing a 6,000-meter depth mining operation.
- Which specific companies are leading or participating beyond general references to Japanese corporate involvement.
- Timeline for potential milestones or a concrete date for commencement or completion, given inconsistent timelines across reports.
- Whether accompanying processing facilities or downstream infrastructure are part of the plan, and where they would be located.
Context
Rare earths are a critical component in many modern technologies, including electronics and defense applications. China has been a dominant supplier in this market, prompting interest from the United States and allied nations in diversifying sources and reducing strategic risk. This topic sits at the intersection of technology, geopolitics, and supply-chain resilience, with broader regional implications in the Indo-Pacific region.
Why It Matters
Confirming a cross-national effort to access and develop deep-sea rare earth resources could influence global supply dynamics, investment in mining technologies, and regulatory standards for underwater extraction. The development may also affect perceptions of competition with China over technology and resources that underlie many advanced industries.
What to Watch Next
- Any official announcements clarifying the status—proposal, approval, or active development—from US and Japanese authorities.
- Details on participating companies, investment levels, and the regulatory framework governing deep-sea mining in the vicinity.
- Updates on environmental impact assessments, technology readiness for deep-sea extraction, and potential processing plans.
- Reactions from other major players in the rare earths market and any shifts in supplier diversification strategies.
