Japan is stepping up a decade, long initiative to extract rare earth metals from the ocean floor with the ultimate aim of reducing its dependence on China the major world producer of these critical minerals. The jointly supported plan by government ministries and research institutes, is not only intended to ensure a stable supply chain for the tech sectors, but also to raise Japan’s economic and security status.<\/p>\n

However, the market for rare earth metals on a global scale is characterized by an extremely high degree of concentration. China’s share of the world’s total production of rare earth minerals from mining is close to two, thirds, and it accounts for more than 90% of the world’s refined rare earths, thereby providing China with enormous power in terms of prices and supply control.<\/p>\n
Japan’s initiative intends to bring the recovery of rare earth, rich deep, sea mud from its exclusive economic zone (EEZ) around Minami, Torishima to the market. The location is thought to be so heavily laden with deposits that, in some evaluations, they are equivalent to several million tons of rare earth elements, which could be enough to significantly diversify the supply.<\/p>\n
