Core Viewpoint - Japan's strategies to secure rare earth supplies are ineffective against China's overwhelming price advantage, necessitating significant reserves to mitigate dependency on Chinese exports [2][6]. Group 1: China's Dominance in Rare Earths - China possesses vast reserves of rare earth minerals and low extraction costs, making it the most competitive supplier globally [4]. - Even with high-quality rare earth sources in Australia and the U.S., the cost of transporting and processing in China remains lower, reinforcing China's market position [4]. - China's production of electric vehicles (EVs) has shifted its focus from export markets to domestic consumption, allowing it to impose stricter export controls without economic repercussions [5]. Group 2: Japan's Dependency and Strategies - Japan's reliance on Chinese rare earths has decreased from 90% in 2012 to 70%, but efforts to diversify sources have not yielded significant results [6]. - The Japanese government is advised to maintain reserves equivalent to one year's global demand to support allies in times of need [10]. - Japanese companies have reportedly made adequate preparations for potential supply disruptions from China [10]. Group 3: Recycling and Alternatives - Recycling rare earths in Japan is costly and generates waste, making it less economically viable compared to direct procurement from China [8]. - Japan has advanced technology in rare earth recycling and alternative materials, which could contribute to global efforts in this field [9]. Group 4: Future Supply Dynamics - The global supply of rare earths is not at risk of depletion, with land-based reserves sufficient for over 1,000 years, even if the U.S. were to supply the market [12].
