Japan sets sail on rare-earth hunt as China tightens supplies

A Japanese mining ship departed on Jan 12 for a remote coral atoll to probe mud rich in rare earths, part of Tokyo’s drive to curb its reliance on China for critical minerals as Beijing tightens supply.

The month-long mission of the test vessel Chikyu near Minamitori island, some 1,900km southeast of Tokyo, will mark the world’s first attempt to continuously lift rare earth seabed sludge from 6km deep onto a ship.

Japan, like its Western allies, has been reducing its dependence on China for the minerals vital to the production of cars, smartphones and military equipment, an effort that has taken on urgency amid a major diplomatic row with Beijing.

“After seven years of steady preparation, we can finally begin the confirmation tests. It is deeply moving,” Mr Shoichi Ishii, the head of the government-backed project told Reuters, as the vessel left the port city of Shizuoka.

“If this project succeeds, it will be of great significance in diversifying Japan’s rare earth resource procurement,” he said, adding that recovering the key minerals from 6km below sea level would be a major technological achievement.
