Over 200 million metric tons of rare metals found near remote Tokyo island

Over 200 million metric tons of manganese nodules rich in rare metals have been discovered on the seabed near Minamitorishima, a remote Tokyo island, according to the Nippon Foundation and the University of Tokyo. These nodules, found at depths of 5,000 meters in Japan's exclusive economic zone, are rich in cobalt and nickel, essential for lithium-ion batteries. The estimated deposits could meet Japan's nickel consumption for 75 years and cobalt needs for 11 years. The discovery, initially identified in 2016, has now been verified through detailed surveys conducted earlier this year. Plans are underway to extract 2,500 metric tons per day in an experimental project by March 2026. Researchers emphasize the importance of developing this resource to support Japan’s industries and foster innovation in ocean-based industries.
