Japan Successfully Retrieves Rare-Earth Seabed Mud

Japan’s government announced on Monday, February 2, 2026, that it has successfully collected rare-earth-rich mud from the seabed for the first time. The mud was retrieved from a depth of about 6 kilometers (4 miles) during a test mission.

A Japanese scientific drilling ship left on January 12 to explore areas near the remote Minamitori Island. The mission aimed to collect mud containing rare-earth minerals, which are very important for electronics, renewable energy, and other advanced technologies.

This effort is part of Japan’s plan to reduce its dependence on China for critical minerals. China currently controls much of the world’s supply of rare-earth minerals, and recent restrictions from Beijing have made it difficult for other countries to access them.

By successfully retrieving the rare-earth-rich seabed mud, Japan is taking a major step toward securing its own supply of these important minerals. The government hopes this will strengthen its industrial independence and support the country’s technology and energy sectors.
