Core Insights - Japan's ambition for rare earth independence has proven to be a strategic miscalculation, underestimating China's dominance in the global rare earth market and overestimating its own technological capabilities [1][14] Group 1: Historical Context - In 2010, China imposed rare earth export restrictions on Japan, reducing exports from 50,000 tons in 2009 to approximately 30,000 tons in 2011, resulting in a 40% supply shortfall [3] - This led to significant disruptions in Japan's manufacturing sector, particularly affecting the automotive industry, which faced production halts due to insufficient rare earth supplies [3] Group 2: Japan's Response and Actions - Following the 2010 crisis, Japan initiated a rare earth breakthrough plan, investing heavily to reduce reliance on Chinese supplies, but this effort was ultimately disrupted by India's export halt in June 2025 [4][5] - Japan engaged in various partnerships, including with Mongolia and Australia, and invested in rare earth recycling in France, spending over 100 billion yen on these initiatives [4] Group 3: Challenges Faced - Japan's agreement with India to source rare earths turned out to be ineffective, as India lacked the technological capacity to provide sufficient raw materials, leading to Japan purchasing rare earths that were originally sourced from China [4][5] - Attempts to develop alternative technologies, such as Sony's effort to recycle rare earths from old PS4 consoles, yielded minimal results, recovering only 200 kg from 100,000 units [7] Group 4: Resource Exploration and Limitations - Japan identified significant rare earth deposits near Minami-Torishima in 2013, but the high costs and technical challenges of deep-sea mining have hindered extraction efforts [9] - The projected cost for initial deep-sea mining trials in 2025 is estimated at 12 billion yen (approximately 83 million USD), with extraction rates being economically unfeasible [9] Group 5: China's Dominance - China's rare earth advantage is not solely based on resource control but on a comprehensive industrial ecosystem that includes mining, refining, and production of downstream materials, maintaining over 60% of the global market share in 2023 [11] - The systemic advantages China has developed over the years ensure its continued leadership in the rare earth sector, making it a challenging competitor for other nations seeking to disrupt this order [13][14]
