TSMC’s Japan Plans Are Now Looking Much More Aggressive, as the Chip Giant Will Produce 3nm Chips in the Region to Support Gigantic AI Demand

TSMC is now looking to expand its fab operations in Kumamoto, Japan, as the chip giant now plans to introduce 3nm production lines, a massive upgrade from the previous plans.

TSMC’s Japan & US Projects Will Be On Par In Terms of Process Technologies Being Produced Within the Same Timeline

The Taiwan chip giant has realized that expanding production in Taiwan alone won’t do the job, given the gigantic node demand from the AI sector. More specifically, it is the advanced processes that are in significant demand by HPC customers, which is why production lines responsible for nodes like 3nm are severely bottlenecked. However, TSMC plans to address this by investing in Japan, as the company’s CEO, C.C.Wei. met with Japan’s Prime Minister Sanae Takaichi, after which it was disclosed that the Kumamoto Fab 2 will now produce 3nm chips.

There were reports a few weeks back that TSMC was increasing its presence in the Japanese semiconductor market, claiming that the company sees rising competition from Rapidus, a Japanese competitor looking to enter the 2nm segment. And given the demand crunch TSMC currently faces, it is viable for the company to look beyond mature processes and focus instead on what its AI customers want. According to reports, the Japanese PM was “flattered” by TSMC’s announcement, calling it “vital” to the nation’s economy.

TSMC’s expansion into Japan is a clear indication that the company has begun to factor in geopolitical uncertainties in its operations in Taiwan. Last month, the Taiwan chip giant signed a major deal with the Trump administration, willing to invest up to $250 billion in Arizona by developing advanced packaging plants, chip fabs, and R&D centers. TSMC also had ambitions to scale up production at its Germany project, but progress has stalled.

The reports don’t indicate when the Kumamoto fab will start producing 3nm chips, but a viable estimate is within the 2027-2028 timeline, similar to when the Arizona facility will begin the same process. Another interesting point is that both Japan and the U.S. will be on equal footing in chip technology production, despite TSMC committing a massive investment in the latter region.
