Japan, US to Explore Rare Earth Mining Near Minamitori Island

Japan-US Rare Earth Mining Partnership: Focus on Minamitori Island

Japan and the US have announced a joint rare earth mining project near Minamitori Island. This strategic initiative aims to reduce dependence on China, which currently dominates global rare earth production. The plan emerged from discussions between Japanese Prime Minister Sanae Takaichi and US President Donald Trump.

The Minamitori site, located approximately 1,900 km southeast of Tokyo, contains rare earth-rich mud. Japan intends to begin feasibility testing in January, targeting extraction from depths up to 6,000 meters. Initial surveys already confirm significant deposits, supporting Japan’s broader plan to enhance domestic rare earth supply.

By collaborating, both nations aim to secure strategic minerals for clean energy, electronics, and defense applications. The framework agreement signed during Trump’s visit to Tokyo formalizes cooperation and signals a shared commitment to reducing global reliance on Chinese production.

Rare Earth Extraction Plans and Strategic Implications

Japan plans to initiate trial operations in January 2027, using systems capable of processing 350 tonnes of mud daily. Officials emphasize that this project aligns with national goals to strengthen economic security and maritime sovereignty.

Rare earth minerals are essential for electric vehicles, wind turbines, and advanced electronics. The US currently accounts for roughly 12% of global production, while Myanmar contributes about 8%. With China leading the market, Japan-US collaboration could reshape supply chains and stabilize pricing for critical materials.

Enhanced domestic production could also drive technological innovation and provide long-term strategic advantages in high-tech industries. As a result, stakeholders across mining, energy, and manufacturing sectors closely monitor this development.
