What exactly did China announce and when?

On February 24-25, reports said China’s commerce ministry expanded controls on dual-use exports to Japan. The move bans shipments to 20 Japanese entities and tightens reviews for 20 more. Items cited include rare-earth components and avionics-grade parts. Tokyo protested and requested withdrawal, calling the measures economic coercion.

Which Japan defense stocks face the highest near-term impact?

Names tied to aero engines, missiles, or radar that use rare-earth magnets and certified electronics face higher risk. Market reports cite Mitsubishi Heavy, Kawasaki Heavy, and IHI among companies flagged. Cross-sector links mean Subaru and ENEOS may also see indirect effects through shared suppliers and qualification delays.

How could China export restrictions affect earnings and valuation?

Costs can rise from spot buying, testing, and added paperwork. Delivery slippage risks penalties on fixed-price contracts, while cost-plus models pass expenses with a lag. Until approvals are clearer, investors may demand a higher risk premium, compressing multiples even if formal earnings estimates move only modestly.

What practical steps can retail investors in Japan take now?

Reduce single-name concentration, check fund fact sheets for heavy industrial weight, and build positions gradually. Watch company disclosures on sourcing, inventory days, and license status. Consider hedges where appropriate, and keep cash for opportunities as clarity improves. Focus on firms with diversified supply and strong customer approvals.
