Japan will conduct test mining of rare-earth-rich mud from the deep seabed off Minamitori Island from January 11 to February 14.
The operation marks the world's first attempt to continuously lift rare-earth mud from a depth of around 6,000 meters onto a vessel.
The project aims to secure stable supplies of critical minerals amid tightening export controls by China.
The Japanese government has invested about 40 billion yen ($280 million) in the project since 2018.
A Chinese naval fleet entered Japan's exclusive economic zone (EEZ) around Minamitori Island during rare-earth surveys in June 2024.
Detailed Insights:
The test will focus on connecting the deep-sea mining system and lifting 350 metric tons of rare-earth mud per day, while monitoring environmental impacts.
If the test is successful, a full-scale mining trial will be conducted in February 2027.
The project is part of Japan's broader efforts to strengthen maritime and economic security amid concerns over resource supply chains.
Rare earth elements (REEs) are essential for various industries, including electronics, renewable energy, and defense, making their stable supply a strategic priority.
China, the dominant supplier of rare earths, has been tightening export controls, prompting countries like Japan to seek alternative sources.
The incident involving the Chinese naval fleet highlights the geopolitical tensions surrounding resource exploration in the EEZ.
Key Concepts Involved:
Rare Earth Elements (REEs): A set of seventeen metallic elements crucial for various modern technologies.
Exclusive Economic Zone (EEZ): A sea zone extending 200 nautical miles from a country's coastline, granting it special rights regarding the exploration and use of marine resources.
Critical Minerals: Minerals essential to modern technologies and economies, with supply chains vulnerable to disruption.
