Japan is set to make history with its groundbreaking deep-sea mineral extraction mission early next year. Starting in January, the country will attempt to retrieve rare earth minerals from 5,500 meters below the ocean’s surface the deepest such trial ever conducted.
This deep-sea mineral extraction mission comes as nations scramble to reduce reliance on China, which currently controls 92% of refined rare earth production. Earlier this week, Japan joined the U.S., India, and Australia in pledging to secure stable supplies of these critical minerals. Rare earth metals are essential for electric vehicles, wind turbines, and advanced military technology.
The Japanese research vessel Chikyu famous for deep-sea scientific drilling—will lead the operation. It will target mineral-rich sediments near Minami Torishima, a remote Pacific island also used as a military outpost. According to Shoichi Ishii of Japan’s Cross-ministerial Strategic Innovation Promotion Programme, this test run will focus on equipment functionality rather than extraction volume.
The Nikkei reports that the mission aims to collect 35 tonnes of seabed mud over three weeks. Each tonne could yield around two kilograms of rare earth elements, crucial for high-tech manufacturing.
The deep-sea mineral extraction mission arrives amid rising tensions over seabed mining. The U.S. has pushed to accelerate international deep-sea mining, while China recently imposed export controls on rare earths. Environmental groups warn that disturbing the ocean floor could devastate marine ecosystems.
Later this month, the International Seabed Authority will discuss regulations for deep-sea mining. Japan’s trial could set a precedent for future underwater resource exploitation. If successful, this deep-sea mineral extraction mission could position Japan as a leader in alternative mineral sourcing. The country hopes to reduce its dependence on foreign supplies while advancing deep-sea mining technology.
As global demand for rare earths surges, Japan’s ambitious project could reshape the future of resource extraction balancing economic needs against environmental risks.
