Japan Plans 'World First' Deep-Sea Mineral Extraction

  • Starting in January, Japan will conduct a trial expedition to collect sediments containing rare earth elements from the seabed near Minami Torishima, located at a depth of 5,500 meters.
  • The mission follows growing concern over China's dominance in rare earth supply and a global push, including from the US, to develop deep-sea mining.
  • The Chikyu vessel aims to recover 35 tonnes of mud over about three weeks, testing mining equipment, with the amount extracted considered unimportant.
  • Each ton of mud contains around two kilograms of rare earth minerals used in electronics and green technology, while a refinery at Minami Torishima is under consideration.
  • The pilot extraction asserts Japan’s push to diversify critical mineral sources amid geopolitical tensions, while environmental groups warn of marine ecosystem risks.
