TSMC’s Overseas Facilities Show Divergent Financial Results with Profitable Chinese Plants and Loss-Making Japanese Site

• March 2, 2026

Taiwan Semiconductor Manufacturing Company (TSMC), a global leader in semiconductor production, continues to experience mixed financial outcomes across its international manufacturing sites. Recent financial data highlights that TSMC’s Chinese factories remain its most profitable overseas operations, while its Japanese facility in Kumamoto faces ongoing financial challenges.

Profitability Divergence Among TSMC’s Overseas Plants

TSMC’s Chinese semiconductor plants primarily focus on mature process technologies, which are proving to be commercially successful and generate significant revenue. These factories have consistently maintained profitability, bolstering TSMC’s global manufacturing portfolio and contributing positively to its overall financial standing.

In contrast, the company’s Kumamoto plant in Japan, established in collaboration with Japanese partners and designed to strengthen local chip production, has reported worsening losses. Despite efforts to optimize production and establish a competitive presence, the plant’s net losses escalated substantially, doubling from $140 million to $309 million in the previous year. This development marks a significant setback for TSMC’s ambitions in diversifying its manufacturing footprint in Japan.

The Kumamoto factory was intended to serve as a key facility in Japan’s semiconductor supply chain, presumably benefiting from local partnerships and regional support. However, the operational costs and other factors have so far prevented the plant from achieving profitability.

This contrast highlights ongoing challenges within the semiconductor industry, where differences in regional market dynamics, technology focus, and operational efficiency deeply impact financial performance. TSMC’s mature-node Chinese factories demonstrate how focused specialization on well-established technologies can sustain revenue generation, while the investment in more complex or emerging market ventures may require longer timelines to realize returns.

The semiconductor market remains highly competitive and capital intensive, with manufacturing facilities often demanding substantial upfront investment and operating expenses before turning profitable. TSMC’s experience underlines the complexities involved in expanding manufacturing capacity internationally, especially in regions aiming to build resilient local supply chains amid global demand fluctuations.

Overall, TSMC’s overseas manufacturing network presents a varied financial picture, with successful mature-node operations in China juxtaposed against ongoing struggles in Japan. How the company navigates these challenges will be important for its future growth and ability to meet global semiconductor demand.

TSMC’s Chinese factories lead in profitability, while its Japanese plant in Kumamoto sees increasing losses despite operational efforts.
