[Tokyo, Tokyo, Japan] Seize property/assets — JAPAN → CHINA

Supply-chain Risk Briefing

1. Summary

On April 17, 2026, Japan implemented economic sanctions against China in Tokyo, including asset seizure/confiscation measures. This action, measured at a tension index of -9.2, suggests deteriorating economic relations between the two countries and is likely to have significant impact on East Asian supply chains.

2. Supply-chain impact

• Bilateral trade disruption risk: Direct trade route blockage between Japan and China expected to disrupt key industrial supply chains including electronic components, automobiles, and chemical products
• East Asian logistics network restructuring: Asset freezes of Japanese companies in China will necessitate rapid structural adjustments to regional production and distribution networks
• Pressure to secure alternative supply sources: Japanese manufacturers' accelerated shift to third-country supply chains in Southeast Asia, India, etc. will increase short-term supply instability
• Global technology supply chain fragmentation: Deepening decoupling between the two countries in advanced technology sectors like semiconductors and precision machinery will reduce global supply chain efficiency
• Surge in maritime shipping costs: Reduced intra-East Asian cargo volumes and increased rerouting will create upward pressure on Asia-Pacific route freight rates

3. Watch points

• China's retaliatory measures: Need to track potential counter-sanctions targeting Japanese companies or restrictions on exports of key raw materials such as rare earth elements
• Regional trade bypass routes: Required monitoring of increased indirect trade patterns via third countries like South Korea and Taiwan and resulting logistics cost fluctuations
• Global corporate responses: Important to track adjustment plans for China operations and supply chain relocation strategies of Japanese multinational corporations like Toyota and Sony
