While multiple countries possess rare earth deposits, the complex processing infrastructure required to transform raw materials into usable components remains heavily centralised. This processing bottleneck affects global manufacturers across automotive, electronics, renewable energy, and defence sectors.

What Triggered Recent Policy Developments?

Diplomatic Context Behind Supply Chain Security

According to Japan's Trade Minister, Ryosei Akazawa, speaking in November 2025, there are currently no particular changes in China's export control measures on rare earths and other materials. This statement came amid broader diplomatic efforts between Japan and China to ease tensions, particularly regarding escalating disputes over Taiwan and regional security concerns.

The stability in export control policies reflects the complex balancing act both nations face between economic interdependence and strategic competition. Trade negotiations continue to influence decision-making around critical mineral access, creating periods of relative stability while underlying tensions persist. Furthermore, the critical raw materials transition has become a key factor in shaping these diplomatic discussions.

Historical Patterns in Export Control Implementation

China's approach to rare earth export controls has evolved significantly since establishing formal restrictions in 2010. The current framework operates through sophisticated licensing mechanisms that provide flexibility for case-by-case evaluation while maintaining strategic oversight. Key elements include:

• Provincial-level licensing authority for specific rare earth categories
• Military application restrictions with automatic rejection protocols
• Enhanced monitoring of processing equipment exports
• Graduated control levels based on strategic importance classifications

How Japan Responded to Supply Chain Vulnerabilities

The 2010 Supply Disruption Experience

Japan's rare earth security strategy was fundamentally reshaped by the September 2010 supply disruption. Following a territorial dispute over the Senkaku Islands, Chinese rare earth exports to Japan were suspended for approximately two months, creating immediate manufacturing bottlenecks across multiple industries.

The economic impact was severe and immediate:

• Automotive sector: Toyota, Honda, and Nissan experienced production constraints affecting permanent magnet motor manufacturing
• Electronics industry: Sony and Panasonic faced component shortages disrupting consumer product assembly
• Price volatility: Dysprosium prices increased by 250-400% within three months of the disruption
• Defence implications: Military contractors flagged critical supply vulnerability concerns

This crisis exposed Japan's overwhelming dependence on Chinese rare earth processing, with virtually zero alternative supply sources available for immediate deployment. The disruption demonstrated how geopolitical disputes could rapidly translate into supply chain shocks affecting advanced manufacturing sectors.

Strategic Diversification Initiatives

Following the 2010 experience, Japan implemented comprehensive supply chain diversification strategies designed to reduce single-source dependency risks. These initiatives encompass multiple approaches to supply security, with particular emphasis on energy security in minerals becoming a national priority:

Government-Level Response:

• Establishment of strategic rare earth stockpiles managed through rotation policies
• Budget allocation increases for critical mineral security programs
• Enhanced diplomatic engagement with alternative supplier countries
• Regulatory framework development for deep-sea mining exploration

Corporate Diversification Efforts:

• Direct investment in overseas mining and processing projects
• Technology development partnerships focusing on recycling capabilities
• Alternative material research and substitution programmes
• Supply chain mapping and vulnerability assessment initiatives

The Japanese government's strategic stockpiling programme maintains reserves of critical rare earth elements, though specific quantities remain classified for security reasons. This approach provides buffer capacity during supply disruptions whilst alternative sources are activated.
