Japan has successfully retrieved rare earth elements from deep-sea sediment near Minamitori-shima island. This marks a potential step towards industrializing domestic rare earth production and reducing reliance on China's dominant supply chain.
This development could significantly alter global supply chains for critical minerals, reducing geopolitical risks associated with China's dominance and potentially boosting Japan's technological and defense industries.
Japan has successfully retrieved rare earth elements from deep-sea sediment during a drilling test near the remote Pacific island of Minamitori-shima. The achievement, announced by Prime Minister Sanae Takaichi, is considered a world first for rare earth retrieval at a depth of nearly 6,000 meters.
The successful test is a significant step toward industrializing domestic rare earth production in Japan and reducing its reliance on China, which currently dominates the global supply chain for these critical minerals. Rare earths are essential components for semiconductors, electric vehicles, and defense applications.
Japanese researchers first discovered deposits rich in critical minerals, including rare earths, around Minamitori-shima in the 2010s. The country has been working on research and development in this area under its Strategic Innovation Promotion Program.
The move comes amid growing geopolitical tensions, particularly concerning China's control over rare earth production and recent suspensions of dual-use goods exports to Japan. This initiative aims to establish resilient supply chains for critical minerals, avoiding overdependence on any single nation.
