China has maintained a complete export embargo on heavy rare earths—gallium, dysprosium, terbium, yttrium—to Japan since January 2025, with June data showing zero shipments across all controlled materials. The restriction, triggered by Japanese PM Takaichi's Taiwan comments in November 2024, is now affecting Japan's semiconductor and aerospace sectors and serves as Beijing's primary leverage in geopolitical negotiations.

This Wire brief sits within Fusion42's coverage of Semiconductors. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur reasons over.

The Wire takeaway

If you make semiconductor, magnet, or aerospace equipment in Japan or source from Japanese suppliers, your rare earth supply just became your geopolitical risk. China is now systematically starving Japan of inputs it cannot substitute or source elsewhere—expect your customers to demand nearshoring or stockpiling within weeks.
