TLDR
- Taiwan Semiconductor Manufacturing will manufacture 3-nanometer chips at its Japan facility, marking its first advanced chip production outside Taiwan and the U.S.
- Investment in the Kumamoto site jumps to $17 billion from the original $12.2 billion plan.
- The chip maker plans $56 billion in capital spending for 2026, up 30% year-over-year.
- 3nm chips power AI systems, premium smartphones, and autonomous vehicles for clients like Nvidia and Apple.
- Construction on the second Kumamoto fabrication plant started in late 2025.
Taiwan Semiconductor Manufacturing is upgrading its Japan operations in a big way. The company will produce 3-nanometer chips at its Kumamoto facility.
This represents a major shift from the original plan. TSMC initially planned to manufacture older 6nm to 12nm chips at the Japanese site.
TSMC Chairman C.C. Wei announced the upgrade during a meeting with Japanese Prime Minister Sanae Takaichi. The news signals Japan’s growing role in the global semiconductor supply chain.

The investment for the facility now reaches $17 billion. That’s up from the initial $12.2 billion budget announced earlier.
Strategic Production Diversification
The 3-nanometer chips represent cutting-edge semiconductor technology. These advanced chips are essential for AI computing systems, high-end smartphones, and self-driving vehicles.
TSMC already committed $165 billion to U.S. manufacturing operations. The Japan expansion adds another geographic location for advanced chip production outside Taiwan.
This diversification strategy addresses supply chain concerns. Companies increasingly want chip production spread across multiple regions.
Japan offers subsidies and partnerships to attract semiconductor manufacturers. The country aims to rebuild its domestic chip industry and reduce foreign dependence.
Construction on the second Kumamoto fabrication plant began in late 2025. The updated plans now include 3nm production capabilities in the facility’s next phase.
Record Capital Spending Plans
TSMC announced plans to spend up to $56 billion on capital expenditures in 2026. The figure marks a 30% increase compared to 2025 spending.
Company executives expect high capital spending levels to persist for three years. The investment wave responds to explosive demand for AI-focused semiconductors.
TSMC manufactures chips for Nvidia, the leading AI semiconductor company. The chipmaker also produces processors for Apple’s iPhone lineup.
Qualcomm sources its mobile chipsets from TSMC. Advanced Micro Devices relies on TSMC for processor manufacturing as well.
The company faces emerging competition from Rapidus, a Japanese government-backed semiconductor manufacturer. Rapidus plans to produce 2-nanometer chips by 2027 with backing from major domestic tech firms.
Wall Street analysts maintain a bullish outlook on TSM stock. The consensus rating stands at Strong Buy based on seven Buy ratings and one Hold rating.
The average price target sits at $396.83, implying 21.82% upside potential from current levels. Analysts see the geographic diversification and capacity expansion as positive catalysts.
TSMC’s Japan facility upgrade demonstrates the company’s commitment to meeting global chip demand. The $17 billion investment brings the world’s most advanced chip production to Japanese soil for the first time.
