Japan will conduct test mining of rare-earth-rich mud from the deep seabed off Minamitori Island, some 1,900 kilometres (1,180 miles) southeast of Tokyo, from January 11 to February 14, the head of the government-backed project said.
The operation will mark the world's first attempt to continuously lift rare-earth mud from a depth of around 6,000 meters on to a vessel.
Tokyo, like its Western allies, is seeking to secure stable supplies of critical minerals as China, the dominant supplier of rare earths, tightens export controls.
"One of our missions is to build a supply chain for domestically produced rare earths to ensure stable supply of minerals essential to industry," Shoichi Ishii, program director of the Cabinet Office's national platform for innovative ocean developments, told reporters.
The Japanese government is pressing ahead with a national project as part of broader efforts to strengthen maritime and economic security.
The January test will focus on connecting the deep-sea mining system and confirming its ability to lift 350 metric tons of rare-earth mud per day. Environmental impacts will be monitored both on board and on the seabed throughout the operation.
No production target has been set, but if successful, a full-scale mining trial will
