Japan to Begin Test Mining Rare-Earth Elements from Seabed Mud
Japan is launching a groundbreaking deep-sea mining initiative to extract rare-earth elements from mud near Minamitori Island starting in early 2026, aiming to become the world's first to mine these resources specifically from deep seabed mud. The project, driven by national security rather than profit, seeks to reduce Japan's dependence on imported rare earths—especially from China—by securing a domestic supply of critical minerals like dysprosium, neodymium, gadolinium, and terbium, essential for high-tech industries. Operating at depths of 5–6 km, the effort faces significant engineering challenges, requiring advanced robotics, pressure-resistant equipment, and innovative extraction technologies. By 2027, Japan plans to recover 350 tonnes of mud daily, analyzing and refining it to assess large-scale viability. This state-backed effort reflects a strategic investment in resource security and technological leadership, with potential global implications for mineral sourcing, environmental standards, and deep-sea mining practices.
