Japan Nears Critical Yttrium Shortage as China Tightens Rare Earth Exports

Japan is staring down a major manufacturing crisis, with officials sounding the alarm that the nation is 'months' away from running out of yttrium, a vital rare earth element, as China continues to squeeze supply. Tokyo has urgently called on the US to help convince Beijing to ease its tight export controls on this critical mineral, which is essential for industries from jet engines to advanced semiconductors. This escalating standoff is threatening to halt production lines across the globe by year-end if a solution isn't found fast. The sudden crunch comes as Beijing has drastically cut yttrium exports to Japan, with shipments down a staggering 74% in the first half of 2026 compared to two years prior, and September seeing only a fraction of previous volumes. This move is largely seen as China's response to rising geopolitical tensions, including the ongoing trade war initiated by former US President Donald Trump and recent remarks from Japanese Prime Minister Sanae Takaichi regarding Taiwan. The price of yttrium oxide outside China has shot up an astonishing 179-fold, reaching $1,150 per kilogram, highlighting the severe market disruption. With US defense supply chain also relying heavily on Japanese components containing yttrium, Washington has already been urging China to increase rare earth flows to its allies and has even reportedly linked approvals for China's Comac C919 jet engines to the yttrium supply. The US-Japan critical minerals 'rapid response group' met recently to address these urgent issues. While Japan has tried for years to reduce its overall rare earth dependence on China, finding alternatives for heavy rare earths like yttrium remains a long-term challenge, making immediate diplomatic action crucial to avert a wider global economic ripple effect.
