Japan is stepping up a decade, long initiative to extract rare earth metals from the ocean floor with the ultimate aim of reducing its dependence on China the major world producer of these critical minerals. The jointly supported plan by government ministries and research institutes, is not only intended to ensure a stable supply chain for the tech sectors, but also to raise Japan’s economic and security status. Why Rare Earths Matter Early February 2026, the deep, sea drilling vessel Chikyu had really done the job of lifting a rare earth element, carrying sediment from 6, 000 meters, the very first rare
