Japan’s government is broadening its subsidy program to support domestic production of legacy—or mature—semiconductors, according to a report from Nikkei Asia. The move is aimed at reducing reliance on imports for chips used in automobiles, home appliances, and industrial equipment, as global supply chain vulnerabilities persist. The expanded initiative could provide financial backing to a wider range of manufacturers and technology nodes.

Japan’s Ministry of Economy, Trade and Industry (METI) is reportedly widening the scope of its existing subsidy framework for the domestic semiconductor industry, according to Nikkei Asia. The updated program will offer financial support specifically for “legacy” chip production—semiconductors based on mature process nodes (typically 28 nanometers and above). These chips are widely used in products such as automobiles, medical devices, and factory automation systems.
The expanded subsidies are seen as part of Tokyo’s broader strategy to secure its semiconductor supply chain and reduce dependence on imports from countries like China and Taiwan. Under the revised scheme, METI is likely to cover a larger portion of capital expenditure and operating costs for chipmakers that invest in fabrication facilities (fabs) dedicated to legacy processes.
Industry observers note that while the global chip shortage that peaked in 2021–2023 has largely eased, demand for legacy semiconductors remains stable, particularly in the automotive and industrial sectors. Japan, home to chipmakers such as Renesas Electronics, Rohm, and Toshiba, is positioning itself to capture a larger share of this market segment.
The subsidy expansion builds on Japan’s earlier “chip fund” initiatives, which allocated roughly ¥1.3 trillion ($9.3 billion) for advanced semiconductor production, including support for Taiwan Semiconductor Manufacturing Co.’s (TSMC) Kumamoto fab. The new legacy-focused scheme could supplement those efforts by targeting the lower-margin but high-volume chip categories where Japan already has competitive strengths.
No specific budget amount or eligibility criteria have been released yet for the expanded subsidies, but METI is expected to finalize details in the coming weeks. The government is also consulting with domestic chipmakers and industry groups to tailor the program effectively.

Key Highlights
- Policy expansion: Japan is broadening subsidies to cover legacy chip production, moving beyond earlier support that focused on advanced-node manufacturing. Legacy nodes (≥28nm) are used in many non-bleeding-edge applications.
- Supply chain resilience: The initiative reflects Japan’s ongoing effort to reduce dependence on imported chips—especially from Taiwan and China—for essential industrial and automotive components.
- Target industries: The subsidies are designed to benefit sectors where Japan is a major producer, such as automotive electronics, robotics, and medical devices, which rely heavily on mature chips.
- Company impact: Japanese chip manufacturers like Renesas, Rohm, Toshiba, and others could be eligible to receive government support to upgrade or expand legacy fab capacity.
- Complement to existing programs: This move follows Japan’s earlier investment in advanced semiconductor production (e.g., TSMC’s Kumamoto fab) and is part of a comprehensive national chip strategy.
- Regional implications: Strengthening domestic legacy chip production could reduce Japan’s import dependency while potentially increasing competition with other Asian chipmaking hubs like South Korea and China, which also focus on mature nodes.

Expert Insights
From a market perspective, Japan’s expanded subsidy for legacy chips signals a pragmatic shift in policy—acknowledging that advanced chips (sub-7nm) are only one piece of the semiconductor landscape. Many analysts consider mature-node semiconductors essential for the “electrification” and “automation” trends in automotive and industrial end-markets. By supporting legacy production, Japan could potentially reduce supply chain risks and reinforce its position in automotive supply chains.
However, the long-term success of the subsidy program may depend on execution—particularly on whether Japanese chipmakers can achieve cost competitiveness compared to larger producers in China and Southeast Asia. Legacy chip margins are typically lower than advanced nodes, so any subsidy must be large enough to encourage sustained investment without creating market distortions.
Investors and industry watchers should monitor METI’s upcoming announcements for precise subsidy amounts and eligibility requirements. If the program is structured well, it could provide a tailwind for domestic chipmakers and equipment suppliers, as fab expansions would require increased orders for Japanese semiconductor manufacturing equipment (SME) and specialty materials.
At the same time, global oversupply of legacy chips is a potential risk. If many countries (including the U.S., EU, and South Korea) simultaneously push national legacy chip production, oversupply could pressure prices and profitability. Japan’s policy, while supportive, may need to target specific niche legacy applications where Japanese manufacturers hold technological advantages—such as automotive-grade reliability chips or power semiconductors—rather than pure bulk production.
