Group 1 - Japan's reliance on rare earths from China remains high, with over 60% dependency as of 2025, particularly for heavy rare earths essential for electric vehicles and semiconductors [2] - Japan has invested over 50 billion yen in deep-sea mining to extract rare earths, but the technology is complex and costs are significantly higher than land mining, with commercial viability still uncertain [2] - Efforts to develop rare earth-free magnets have not yielded satisfactory results, as performance is inferior or production costs are prohibitively high, making it difficult to meet current demand [2] Group 2 - Japan's attempts to reduce dependence on China for rare earths have been extensive but ineffective, with a focus on alternative sources without addressing technological shortcomings [4] - China controls 90% of global rare earth refining technology, which poses a significant challenge for Japan's strategy to diversify supply sources [4] - The situation highlights the importance of global cooperation and the need for countries to maintain resilient supply chains rather than pursuing decoupling strategies [4]
