为了降低对华依赖，日本将启动深海稀土开采计划

Core Viewpoint - Japan is attempting to reduce its reliance on China for rare earth materials by initiating deep-sea rare earth mining while facing tightened export controls from China on dual-use items, including those for civilian purposes [1][4][10]. Group 1: Export Controls and Impact - China has tightened export controls on rare earth products to Japan, affecting both military and civilian sectors, with reports of increased difficulty in obtaining export licenses [1][4]. - Japanese companies are experiencing delays in the approval process for export licenses, with procurement cycles for neodymium-iron-boron magnets extending from 1-2 months to 3-4 months [4][5]. - The Chinese authorities are conducting strict checks on the end-user identity and purpose of rare earth products, leading to a significant reduction in the frequency of export license approvals [4][5]. Group 2: Japan's Deep-Sea Mining Initiative - Japan plans to launch a deep-sea rare earth mining trial on January 11, aiming to extract resources from a site near Minami-Torishima, which is estimated to contain over 16 million tons of rare earths, ranking third globally [5][6][9]. - The deep-sea mining project is seen as a crucial step for Japan to secure its domestic supply chain for critical industries, with the potential to significantly reduce dependence on Chinese imports [8][10]. - The mining operation will utilize the research vessel "Chikyu" to collect rare earth-rich mud from a depth of 6,000 meters, marking a global first in such deep-sea mining efforts [5][9]. Group 3: Strategic Responses and Industry Outlook - Japan's strategy to mitigate supply chain risks includes collaboration with G7 nations and investment in domestic mineral processing capabilities through the Japan Oil, Gas and Metals National Corporation (JOGMEC) [10][11]. - The Japanese government is closely monitoring the situation and is prepared to take appropriate measures to ensure the smooth transport of essential materials amid rising tensions with China [5][10]. - Analysts suggest that while Japan's efforts to establish alternative supply chains are underway, the challenges of rebuilding the rare earth industry outside of China remain significant due to a lack of experience and technical expertise [11].
