A Japanese marine research agency is set to develop an advanced autonomous underwater vehicle (AUV) by fiscal 2028 to enhance the search for rare earth elements and other mineral resources in the seabed near Minamitorishima, Japan's easternmost territory. This initiative, announced on June 3, 2026, aims to secure a stable supply of these critical materials, which are essential for various high-tech industries. The project reflects Japan's ongoing efforts to reduce its dependence on foreign sources, particularly China, amid rising global demand for rare earths. The development of this hybrid vessel is expected to significantly accelerate exploration and retrieval processes in the region, positioning Japan as a key player in the global rare earth supply chain.
