TSMC's Japanese subsidiary JASM posted a quarterly profit of NT$951 million (about $30 million / ¥4.78 billion) in Q1 2026 — the first time the Kumamoto fab has been in the black since mass production began in December 2024. We unpack what the 14-month turnaround means against the backdrop of Japan's ¥1.23 trillion in subsidies, the Sony-Denso-Toyota partnership, TSMC's Arizona and Dresden expansions, and Rapidus's high-stakes 2nm bet.
Just three days after Denso's withdrawal, Mitsubishi Electric CEO Kei Urutsuma declared he wants to spin off only the power semiconductor businesses of all three companies and form a joint venture. This proposes a different framework from Rohm and Toshiba's full semiconductor integration plan, adding a new wrinkle to the world No.2 alliance vision. We analyze competition with Wolfspeed, Infineon, and STMicroelectronics, the SiC market share battle, and the impact on the EV industry.
