- Officials reported that a government-backed mission successfully retrieved rare-earth-bearing seabed mud from roughly 6 km beneath the surface near Minamitori Island.
- The drill ship is scheduled to head back to Shimizu port on Feb. 15 for volume and mineral content analysis.
- TDK reports that Chinese export controls have made securing rare-earth materials “extremely difficult” and is ramping up efforts to diversify its sources.
Japan’s government announced it has successfully recovered rare-earth-rich seabed mud from depths near 6,000 metres. This test mission marks the first time the material has been continuously lifted to a ship, a feat officials say is a global first. (Reuters)
This outcome is crucial now as Tokyo moves to secure rare earth supplies—a set of metals vital for powerful magnets in EV motors and electronics—amid tightening Chinese restrictions and mounting pressure on companies.
Last month, China halted exports of certain “dual-use” items—products with both civilian and military applications—to Japan, fueling tensions in their diplomatic spat and reigniting concerns over supply chain security.
The month-long mission took place on the drilling ship Chikyu near Minamitori Island, roughly 1,900 km southeast of Tokyo. Recovery operations kicked off on Jan. 30, and officials confirmed the first successful lift by Feb. 1. The team wrapped up work at three separate sites, they said.
The recovered mud is thought to hold elements like dysprosium and neodymium, key for EV motor magnets, along with gadolinium and terbium, which find use in various high-tech products. Samples are set for analysis once the ship docks in Shimizu on Feb. 15.
“Barring major issues,” Ayumi Yoshimatsu, spokeswoman for the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), said Japan aims to begin full-scale mining trials in February 2027.
Government spokesman Kei Sato said officials will “analyse the details” to determine the rare earth content in the sample, describing the retrieval as “a meaningful achievement” for economic security. Shoichi Ishii, programme director for the National Platform for Innovative Ocean Developments, emphasized the effort was “about economic security” and ensuring a stable supply chain.

The supply shock is hitting boardrooms hard. TDK’s CFO, Tetsuji Yamanishi, described material procurement as having reached an “extremely difficult stage” during an earnings briefing. He noted the impact started last year, and the company has been relying on stockpiled materials to keep production running. (Reuters)
Yamanishi noted that TDK is working to diversify its supply chain and is creating technology to produce magnets with little to no rare earth elements. This shift could significantly impact suppliers if shortages continue.
Deep-sea extraction remains full of uncertainties. Japan hasn’t released the sample’s volume or precise mineral content yet. Moving past trial stages would also require overcoming technical challenges, cost issues, and environmental concerns that might delay or scale back the project.
Officials are holding off until after Feb. 15 for the post-voyage analysis. The next key date is the February 2027 mining trial, which will determine if this deep-sea discovery can evolve beyond just a strategic fallback.
