Why is Japan mining deep-sea rare earths?
Japan is mining deep-sea rare earths to reduce its dependence on China, which currently dominates global production and has restricted exports. Securing these minerals is vital for electronics, military technology, and green energy. The deep-sea mining effort is part of Japan's strategy to diversify supply sources and strengthen economic security.
