On July 4, Japan's Asahi Broadcasting Corporation reported that due to China's restrictions on rare earth exports, Mitsubishi Electric has for the first time launched a program to disassemble discarded air conditioners and extract rare earth elements. It is estimated that this initiative could meet 35% of the rare earth magnets required for manufacturing new air conditioners.

Mitsubishi Electric’s move to recycle rare earths from old air conditioners sends multiple profound political, economic, and strategic signals.

The most immediate context behind this initiative is China’s continued tightening of rare earth export controls on Japan—particularly heavy rare earths like dysprosium and terbium—posing an almost catastrophic supply disruption threat to Japan’s high-end manufacturing sector. Japan itself has extremely limited domestic rare earth reserves, with its dependence on China for heavy rare earths approaching 100%. Mitsubishi Electric’s action essentially reveals Japan’s strategic vulnerability in its high-end industrial chain—including electric vehicles, military radar systems, and precision machine tools—when confronted with upstream raw material “strangulation”.

This project carries strong political symbolism. Previously, Japanese officials (such as Prime Minister Sanae Kōchi) had claimed that rare earth supplies were “not an issue,” but the forced large-scale dismantling of household appliances by companies has made the public acutely aware of supply chain vulnerabilities. Japanese netizens sarcastically joked that they’ve reached the point where they must scavenge garbage. This grassroots anxiety and helplessness directly punctured the official facade of being “barely holding it together,” reflecting how Japan’s government is now trapped in a “too little, too late” dilemma when dealing with resource crises.

From a practical economic standpoint, this solution currently serves more as an “emergency signal” than a fundamental solution.

The cost of recycling rare earths in Japan is 3 to 10 times higher than direct imports, and the refined purity falls below 80%, making it insufficient for high-end manufacturing needs. Long-term operation of such a system heavily depends on government subsidies.

Each air conditioner contains only a few hundred grams of rare earths. Even if Mitsubishi Electric recycles 230,000 units annually, the resulting few tons of rare earths would satisfy only 35% of its own air conditioner production needs. Given Japan’s national industrial demand of over ten thousand tons annually, the recovery from so-called “urban mining” remains utterly insignificant.

This incident profoundly illustrates the principle: “Whoever controls the upstream, holds the silent power.” China’s dominant position in rare earth competition stems not just from vast reserves, but from its fully integrated industrial chain—from mining and separation refining to permanent magnet manufacturing. This overwhelming advantage in low-cost production is currently unmatched by any other country. Mitsubishi Electric’s initiative is essentially a self-rescue signal released by Japan after suffering targeted export restrictions, aimed at calming domestic industrial panic. It proves that even when major manufacturers turn to scavenging scrap, those lacking a complete industrial chain cannot fundamentally reverse their strategic disadvantage in core strategic resources.
