TSMC Bets Big on Japan: $23 Billion Plan for Advanced 3nm Chips
TSMC plans a second Japan factory for advanced 3nm semiconductors with an investment exceeding $23 billion to meet AI demand.

The global semiconductor landscape is shifting as Taiwan Semiconductor Manufacturing Company (TSMC) announces ambitious plans to bring its cutting-edge 3-nanometre (3nm) process technology to Japan. Through its subsidiary, Japan Advanced Semiconductor Manufacturing (JASM), the chip giant is preparing a second factory that will see total equipment investment soar beyond USD 23 billion.
Fueling the AI Revolution
The decision to implement 3nm technology is a strategic move to keep pace with the explosive growth of artificial intelligence (AI). TSMC noted that the new facility is designed to meet the surging demand for advanced chips, ensuring that customers in Japan and across global markets have access to the high-performance hardware required for the AI era.
In a statement shared via X, TSMC's Japan account expressed gratitude toward the Japanese government for its support. However, the company clarified that the rollout of production and investment will not happen all at once. Instead, plans will be implemented in phases, contingent upon market demand and continued government backing.
A Growing Footprint in Kumamoto
JASM, the joint venture between TSMC and its partners, is centered in Kumamoto, Japan. This second factory marks a significant leap in the sophistication of chips produced on Japanese soil. But the expansion doesn't stop at logic chips.
In August, TSMC teamed up with Sony Semiconductor Solutions to form another joint venture: the Advanced Vision Semiconductor Manufacturing Corp. Also based in Kumamoto, this partnership focuses on the development and production of next-generation image sensors, with commercial production expected to kick off in 2029.
Financial Momentum
This massive investment comes at a time of unprecedented financial success for TSMC. The company's recent quarterly reports highlight a business booming under the pressure of global chip shortages and the AI gold rush:
- Net Profit: Jumped 68.7 per cent year-on-year to USD 23.86 billion for the July-September quarter.
- Revenue: Increased by 50.9 per cent, reaching USD 46.72 billion.
Commitment to Green Tech
Beyond raw power and profit, TSMC is emphasizing sustainability in its Japanese operations. The company stated that JASM will utilize innovative green manufacturing technologies to ensure that the production of these advanced chips is environmentally considerate.
"Moving forward, JASM will continue to work alongside our partners to provide cutting-edge technology to customers in Japan and around the world... in order to meet the strong demand in the AI era," the company stated.
