Japanese Industrial Strategy and Supply Chain Diversification
Japan's prioritisation of Australian critical minerals projects stems from institutional memory of the 2010-2011 rare earth supply crisis. During this period, China implemented export quotas reducing global allocations by up to 40%, resulting in 30-50% price increases for Japanese electronic manufacturers. This experience highlighted the importance of critical minerals energy transition security.
Japan imports 100% of its rare earth element raw material requirements, with no significant domestic mining operations. This complete dependency drives strategic partnerships with resource-stable democracies offering transparent governance frameworks and established rule-of-law protections.
Japanese manufacturing sectors consuming critical minerals include:
- Electronics and semiconductors: 25-30% of global rare earth production
- Renewable energy systems: 15-20% for wind turbine generators and EV batteries
- Defence applications: 5-10% for classified military specifications
- Healthcare equipment: 3-5% for MRI machines and diagnostic equipment
Japan's Ministry of Economy, Trade and Industry published the "Critical Minerals Strategy 2023," identifying target countries for resource partnerships. Australia ranks as a Tier-1 priority alongside Canada and resource-stable ASEAN nations, reflecting institutional recognition of regulatory certainty and democratic governance alignment.
