TSMC to Produce Advanced 3nm AI Chips: Taiwan Semiconductor Manufacturing Co is the company that makes chips for other companies. They have said that they will make these semiconductors in Japan. This is a deal for Japan because it will help the country make more chips and be more secure. Taiwan Semiconductor Manufacturing Co making these chips in Japan is a boost, to Japans goals. Taiwan Semiconductor Manufacturing Co is taking a step by making these advanced 3nm AI chips in Japan.
The company Confirmed it will produce 3-nanometer (3nm) chips at its second factory in Kumamoto Prefecture which is currently under construction. These cutting-edge chips are critical for artificial intelligence smartphones, robotics, and autonomous vehicles.
Why This Move Matters
Taiwan Semiconductor Manufacturing Co. supplies chips to global tech giants such as Apple and Nvidia making its investment a significant win for Japan as it competes in the global semiconductor race.
Key benefits for Japan include:
- Strengthening economic and national security
- Expanding presence in advanced Artificial intelligence and robotics technologies
- Reducing reliance on overseas chip manufacturing
Prime Minister Sanae Takaichi welcomed the announcement during a meeting with Taiwan Semiconductor Manufacturing Co. Chairman and CEO C.C. Wei in Tokyo.
“This project is extremely meaningful from the perspective of Japan’s economic security,” Takaichi said, expressing strong support for the initiative.
Focus on Artificial intelligence and Future Technologies
The 3nm chips produced in Kumamoto will support industries designated as strategic priorities by the Japanese government, including:
- Artificial intelligence
- Robotics
- Autonomous driving systems
Taiwan Semiconductor Manufacturing Co. first Kumamoto plant, which began mass production in late 2024, manufactures less advanced chips. The second facility marks a major step forward in Japan’s advanced semiconductor capabilities.

Global Expansion and Artificial intelligence Demand
Alongside its Japan investment, Taiwan Semiconductor Manufacturing Co. is also:
- Building new chip plants in Arizona, USA
- Expanding fabrication capacity to meet surging global Artificial intelligence demand
Despite concerns about a possible Artificial intelligence investment bubble, Wei has said customer demand is “real and growing.”
Rising Investment in Chip Production
Taiwan Semiconductor Manufacturing Co. plans to significantly ramp up spending to meet future demand:
- 2025 capital spending: Increased by nearly 40%
- 2026 projected spending: $52–$56 billion, up from $40 billion last year
Wei credited Japan’s forward-looking semiconductor policies as a key factor behind the expansion.
Japan’s Bigger Chip Strategy
Japan is also backing its domestic Chip ambitions by heavily subsidizing Rapidus a local semiconductor firm aiming to mass-produce advanced chips.
The Prime Ministers Office emphasized that hosting a world-class chip facility is a major milestone for the nation’s technological and economic future.
Conclusion
Taiwan Semiconductor Manufacturing Co. decision’s to Manufacture Advanced 3nm chips in Japan Marks a Major shift in global semiconductor production. With Artificial intelligence demand accelerating and government support increasing, Japan is positioning itself as a key player in the next generation of Chip Technology.
