Japan and US plan deep-sea mine
Japan and the United States are preparing to cooperate on deep-sea rare earth mining near Minamitorishima, a tiny Japanese island in the Pacific that is believed to sit above valuable deposits. The site is being examined as a source of heavy rare earths that are important for advanced industries and for reducing dependence on China.
Japan’s Cabinet Office said recent test samples contained significant levels of yttrium, gadolinium and dysprosium. Further drilling is planned, and officials are aiming to shape a commercialization plan by 2028.
A number of North American firms have expressed interest, including Houston-based Deep Reach Technology, which has already held initial meetings with Japanese officials. Japan also plans a one-month full-scale mining test in February 2027, including refining and smelting, as part of a feasibility assessment for domestic rare earth production.
