Japanese Tech Giants Plan to Merge Power Semiconductor Operations

In a bold move to secure its future in the global chip industry, Japan is taking major steps toward industrial consolidation.

As of late March 2026, technology giants Rohm, Toshiba, and Mitsubishi Electric have officially entered into negotiations to merge their power semiconductor divisions.

This strategic alliance aims to create a powerhouse, or a 'national team,' to better compete against international rivals like the German industry leader, Infineon Technologies.

Power semiconductors are essential for modern technology, serving as the backbone for electric vehicles, AI data centers, and renewable energy systems.

This initiative is part of a broader Japanese strategy to revitalize its semiconductor sector by focusing on high-value, specialized niches rather than general foundry manufacturing.

If successful, the new entity could capture roughly 10% of the global market, positioning itself as the second-largest player worldwide and strengthening Japan's position in the high-stakes technology market.
