A Japanese mining vessel has embarked on an expedition to extract rare earth minerals from deep-sea mud. This marks the world’s first attempt to retrieve mineral-rich sediment from the seabed at a depth of approximately six kilometers. The vessel is scheduled to operate for about a month near Minamitorishima, an island located roughly 1,200 miles southeast of Tokyo, to conduct these deep-sea exploration activities. Japan, alongside several Western nations, has initiated the extraction of minerals essential for manufacturing electronic components and military hardware, amidst heightening geopolitical tensions with China.
Shoichi Ishii, the project lead for this government-funded initiative, informed Reuters that this mission follows seven years of extensive preparation. He emphasized that the success of this project would represent a significant breakthrough for Japan in securing its mineral supply. Carrying approximately 130 crew members and researchers, the vessel is expected to return on February 14.
Amidst ongoing diplomatic friction between Japan and China, Beijing has significantly restricted the export of minerals vital for both civilian and military applications. Media reports suggest that China is considering further limitations on mineral exports. This follows a similar instance in 2010 when China curtailed exports to Japan during a period of escalated tension. Since then, Japan has sought alternative suppliers, such as Australia, for materials critical to its automotive industry, effectively reducing its reliance on Chinese imports from 90 percent to 60 percent.
With an investment of approximately $250 million, this project represents Japan’s inaugural effort to secure rare earth minerals within its own sovereign maritime territories.
