Japan has initiated discussions with India to jointly explore rare earth mineral deposits located in the desert state of Rajasthan. This strategic move comes as Tokyo intensifies efforts to lessen its dependence on China for rare earth supplies, which are vital for manufacturing high-performance magnets used in various advanced technologies. The talks highlight a growing trend among countries to secure critical mineral resources amid shifting global supply dynamics.
In recent developments, India’s Mines Minister, G. Kishan Reddy, announced that three significant hard rock rare earth deposits have been identified across Rajasthan and Gujarat, containing an estimated 1.29 million metric tons of rare earth oxides. These deposits represent a substantial opportunity for India to boost its domestic mineral production and for Japan to secure a reliable source of these essential materials. The discovery has sparked interest from international partners, particularly Japan, which signed a preliminary agreement with India last year focused on critical minerals cooperation.
Following this pact, Japanese officials have expressed keen interest in the Rajasthan deposits and are planning to dispatch technical experts to the site to assess the feasibility of extraction and processing operations. While the exact timeline for the experts’ arrival remains undisclosed, the collaboration is expected to involve technology transfer and financial investment from Japan. This partnership aims to facilitate the development of extraction techniques that India currently lacks, especially since hard rock deposits require specialized methods for efficient recovery of rare earth elements.
Japan’s involvement is not limited to funding; the country is poised to contribute advanced technology for mining and processing, ensuring a steady supply of rare earths to meet its industrial demands. This cooperation aligns with Japan’s broader strategy to diversify its mineral sources globally, reducing vulnerabilities associated with overreliance on any single supplier, particularly China. Naoki Kobayashi, deputy director at Japan’s Ministry of Economy, Trade and Industry (METI), confirmed that Japan is exploring mining projects worldwide but refrained from commenting on specific corporate partnerships or technology transfers related to Rajasthan.
India shares Japan’s goal of diminishing dependence on Chinese imports by developing large-scale processing facilities capable of producing rare earth elements with high purity levels. The collaboration could see Japan providing the necessary technological expertise to help India establish these capabilities. Rare earth elements are indispensable for manufacturing permanent magnets used in electric vehicle motors, wind turbines, fighter jets, and drones—sectors critical to India’s rapidly expanding economy and defense infrastructure.
The urgency of this partnership has been underscored by recent geopolitical tensions. Last week, China imposed export restrictions on dual-use items—materials that serve both civilian and military purposes—to 20 Japanese entities accused by Beijing of supporting Japan’s military. This move effectively cuts off Japanese companies from accessing seven rare earth elements and related materials on China’s dual-use control list, alongside other critical minerals. Such restrictions have heightened Japan’s resolve to secure alternative sources through international cooperation.
Beyond rare earths, Japan is also exploring opportunities to collaborate with Indian firms in mining other strategic minerals such as lithium, copper, and cobalt, particularly in African countries. These efforts reflect a comprehensive approach to securing a diversified supply chain for minerals essential to the green energy transition and advanced manufacturing industries. The evolving partnership between Japan and India signals a significant step toward reshaping the global rare earths market and enhancing supply chain resilience amid increasing geopolitical uncertainties.
