TSMC’s subsidiary in Kumamoto, Japan, recorded its first quarterly profit since mass production began at the end of 2024, signaling a milestone for the company's expansion in the region.
- JASM Kumamoto fab achieves NT$951 million profit in Q1 2026.
- Plans shifted from 6nm to 3nm tech for second Kumamoto fab due to AI demand.
- TSMC’s US Arizona fab also posts strong profit growth fueled by AI chip demand.
What happened
The Japan-based semiconductor manufacturing joint venture, JASM, which is 77% owned by TSMC, posted a profit of NT$951 million (approximately $30.19 million) in the first quarter of 2026. This marks the first time the Kumamoto fab has been profitable since it began mass production at the end of 2024. The turnaround follows previous losses of NT$1.39 billion in the preceding quarter and NT$3.25 billion in Q1 2025.
JASM's initial fab uses mature process technologies ranging from 12nm to 28nm, catering primarily to automotive and industrial sectors. The improved financial results reflect better production utilization rates. Construction of the second fab at Kumamoto is underway, with plans recently updated to focus on 3nm technology instead of the previously announced 6nm process to meet growing global demand for AI chips.
Why it matters
TSMC’s milestone profit from its first Kumamoto fab highlights the company’s successful expansion and commercialization outside Taiwan, specifically in Japan. The Kumamoto facility’s focus on mature nodes serves key sectors such as automotive manufacturing, which remains a significant market requiring reliable chip supply chains. Achieving profitability demonstrates operational efficiency improving within a challenging semiconductor industry environment.
Additionally, the shift to a 3nm process for the upcoming second fab shows responsiveness to the booming AI market, where cutting-edge technology nodes are critical. This strategic adjustment underscores TSMC’s positioning to capitalize on the increasing demand for advanced chips in Japan and worldwide, strengthening its competitive advantage amid global chip shortages and geopolitical supply chain diversification efforts.
What to watch next
Monitoring the construction progress and ramp-up of the second Kumamoto fab will be key, as it will use the advanced 3nm process technology intended to support AI and high-performance computing applications. The commercial success of this fab will further signal TSMC’s ability to expand advanced semiconductor manufacturing outside Taiwan effectively.
In parallel, TSMC’s operations in the United States, particularly the Arizona fab, continue to see robust profit growth from AI-related demand. Its forthcoming fabs and assembly plants under construction in Arizona will also be critical to watch for regional semiconductor supply resilience. Meanwhile, in Europe, TSMC’s investment in the Dresden fab remains a development area amid ongoing capital expenditures and losses during construction phases.
