A Shrinking Global Share Is Quietly Reshaping Where Japan's Suppliers Want to Grow

A boom at home, a shrinking seat at the table

Japan's manufacturers are having a good month. The Reuters Tankan sentiment index hit +18 in August — its strongest reading since March — with chemicals and precision machinery leading the charge, both riding a wave of semiconductor-related demand.

Here's the number that doesn't make the headlines: Japan's share of the global semiconductor market has slipped to just 8.2%, according to the SIA Factbook 2025. Domestic order books are full. Global relevance is shrinking. Those two things are happening to the same companies, at the same time.

That combination tends to change how a supplier thinks about growth. A company doing well at home but losing ground globally has every reason to look elsewhere for the next stage of growth — not because it has already decided where, but because staying purely domestic is no longer a strategy that offsets a shrinking global footprint.

The market with room to grow is Europe's

Europe's semiconductor market is projected to grow 11.6% in 2026, to roughly $60.4 billion — driven by exactly the segments Europe already leads: automotive, industrial power control, EV inverters, and the power devices behind the continent's renewable buildout. Infineon, STMicroelectronics, and NXP sit at the centre of that growth, but the materials and precision equipment that feed it are disproportionately Japanese strengths: Japanese suppliers control roughly 31% of global semiconductor equipment revenue, second only to the United States, and in specific process steps — wafer cleaning, coater/developer systems, silicon wafers, photoresists — that share runs as high as 50–88%.

In other words: Europe has some of the fastest-growing demand in exactly the categories where Japanese chemical and equipment suppliers have decades of specialised depth. Whether that turns into new partnerships depends on which side moves first.

Early signs of interest, not yet a rush

There are concrete, if still modest, signs that this interest is forming. In December 2025, JETRO and the EU Business Hub co-hosted a Europe-Japan Semiconductor Innovators Meetup in Tokyo — a matchmaking event built specifically to connect European semiconductor companies with Japanese counterparts. Separately, Kyoto-based Nishimura Ceramics, a mid-sized supplier of semiconductor-related components, has set a public target of raising its overseas revenue share by 20 points to roughly 50% by 2031 — with North America as its primary focus, and Europe and Asia named as additional markets it intends to develop.

This is early-stage interest and government-level matchmaking, not yet a wave of Japanese suppliers actively pursuing European partners. But the underlying incentive — a shrinking domestic share pushing companies to look outward — is structural, not a one-off event, which is why it's worth watching now rather than after it becomes obvious.

The advantage tends to belong to whoever moves first

A supplier looking to diversify out of a shrinking home market generally negotiates differently than one being courted from a position of comfortable strength. Japanese materials and equipment makers have a growing incentive to look at markets like Europe; most, as far as the public record shows, haven't yet settled on where. That's a different situation from one where a supplier has already chosen its partners and terms are fixed — and it's worth understanding while it's still true.

The takeaway

Japan's domestic semiconductor boom is real, and so is its shrinking global share — and that second fact is a structural reason, not a guarantee, that some of its material and equipment suppliers will look more seriously at Europe in the coming years.
