US and Japan to Jointly Explore Rare Earth Mining in Pacific's Minamitori Island

Nov 6, 2025 at 6:54 AM

In a strategic move aimed at lessening global dependency on China for essential rare earth elements, Japan and the United States have unveiled plans to jointly explore the potential for mining these minerals around Minamitori Island in the Pacific. This significant announcement comes as part of a broader effort by both nations to diversify their supply chains and enhance resource security.

Prime Minister Sanae Takaichi of Japan recently confirmed that her nation and the U.S. will embark on a collaborative study to assess the viability of extracting rare earth minerals from the vicinity of Minamitori Island, located approximately 1,900 kilometers from the Japanese mainland. This partnership was formalized following a framework agreement signed during President Donald Trump's recent visit to Tokyo, where securing rare earth supplies was a central theme of discussions. Large reserves of mud rich in these valuable elements have been identified near the island, prompting Japan to schedule feasibility tests for deep-sea extraction, from depths of around 6,000 meters, to commence in January.

This joint venture represents the latest in a series of concerted global actions to diminish reliance on China, which currently holds a dominant position in the rare earth sector. Both the U.S. and Japan have been actively pursuing strategies to secure their access to these critical resources. This includes a proposal from Japan to the U.S. in June for a comprehensive cooperation package targeting supply chains, particularly in response to ongoing U.S.-China trade tensions. Furthermore, the Trump administration and private investors have recently committed $1.4 billion to support rare-earth magnet startups in the U.S., directly challenging China's market control. Additionally, a significant $8.5 billion deal was inked with Australia to bolster critical mineral supply chains and defense collaboration. These diplomatic and economic maneuvers underscore a collective determination to foster a more resilient and diversified global rare earth market.

The collaborative efforts between the United States and Japan to explore rare earth mining symbolize a pivotal shift towards greater resource independence and global supply chain resilience. This initiative not only promises economic benefits but also reinforces the importance of international cooperation in addressing critical resource challenges, paving the way for a more stable and secure future in technology and industry.
