Japan plans to conduct a trial excavation of rare earth elements from the Pacific seabed next year—a strategic move aimed at reducing its reliance on Chinese supplies and securing critical mineral resources. According to Japan’s Ministry of Economy, Trade and Industry and affiliated research institutes, the trial site is located near Minamitorishima (Marcus Island) within Japan’s exclusive economic zone, where seabed sediments contain exceptionally high concentrations of rare earth oxides, particularly heavy rare earths like neodymium and dysprosium essential for electric vehicle motors, wind turbines, and advanced electronics.The trial will employ cutting-edge deep-sea mining technologies, including remotely operated vehicles and specialized collection systems, to assess the feasibility of efficiently and environmentally extracting rare earth-rich mud from depths of around 5,000 meters. If successful, Japan could become the first country to commercially mine rare earths from the deep ocean, significantly enhancing supply chain autonomy for its high-tech industries and potentially reshaping the global rare earth market.However, deep-sea mining raises environmental concerns. Scientists warn that seabed disturbance could damage fragile deep-ocean ecosystems and threaten poorly understood biodiversity. In response, the Japanese government has pledged rigorous environmental monitoring during the trial and collaboration with the international community to develop regulatory standards. Overall, this initiative marks a pivotal step in Japan’s critical minerals strategy, yet it must navigate complex challenges involving technology, economics, and ecological sustainability.
日本计划于明年在太平洋海底开展稀土资源试采作业，此举被视为其减少对中国稀土供应依赖、保障关键矿产安全的重要战略步骤。据日本经济产业省及相关研究机构透露，试挖地点位于日本专属经济区内的南鸟岛（Minamitorishima）附近海域，该区域海底沉积物中富含高浓度的稀土氧化物，尤其是用于制造电动汽车电机、风力发电机和精密电子设备所需的钕、镝等重稀土元素。此次试采将采用新型深海采矿技术，包括遥控无人潜水器和专用采集系统，以测试从水深约5000米的海底高效、环保地提取稀土泥的可行性。若试验成功，日本有望在未来实现商业化开采，成为全球首个从深海大规模获取稀土的国家。这不仅有助于提升其高科技产业供应链的自主性，也可能重塑全球稀土市场格局。然而，深海采矿也引发环保担忧。科学家警告，海底扰动可能破坏脆弱的深海生态系统，影响尚未被充分研究的生物多样性。因此，日本政府表示将在试采过程中严格监测环境影响，并与国际社会合作制定相关规范。总体而言，这一计划标志着日本在关键矿产战略上的重大突破，同时也面临技术、经济与生态平衡的多重挑战。
