Japan, once blindsided by China’s 2010 rare earths embargo, has spent the last decade actually preparing for a repeat — unlike most of the West, which still seems surprised minerals don’t grow on trees.
Tokyo’s strategy included stockpiling materials, promoting recycling, investing in alternative technologies, and pouring money into non-Chinese projects like Australia’s Lynas.
These efforts slashed Japan’s dependence on Chinese rare earths from over 90% to under 60%, with plans to push it below 50% this year.
The country’s industrial policy pivot made it far more resilient to China’s recent export ban on critical minerals used in EVs, robotics, and defense.
Meanwhile, Western automakers are scrambling, with Suzuki halting production of its Swift model and Nissan now begging for flexibility in sourcing.
China currently controls 70% of rare earth mining and nearly 90% of global processing, making it the inescapable puppet master of the clean tech supply chain.
Despite Japan’s head start, it still struggles with sourcing heavy rare earths, which Lynas has only recently begun producing outside of China.
The export bans, conveniently rolled out during trade tensions with the U.S., exposed just how deep Western dependence goes — and how laughably unprepared much of the world remains.
Europe and the U.S. are now rushing to fund local projects and processing plants, but without serious subsidies, most non-Chinese ventures are unlikely to survive long enough to matter.
Japan’s strategy, forged in crisis, now serves as both a case study and a cautionary tale: diversify early or panic later.
