Even TSMC's record 9 trillion yen investment can't meet AI chip demand. Amid supply shortages, Japan's Rapidus challenges 2nm mass production. We analyze Japan's semiconductor comeback potential through short TAT strategy and economic security perspectives.
As economic security rises up the agenda, Japan is moving to strengthen its semiconductor supply chain through cross-company information sharing and standardized specifications. The MUFG-NTT Data platform, the government's ¥10 trillion support framework, and the designation of semiconductors as a national strategic technology.
NVIDIA's Vera Rubin, AMD's full Instinct MI400 lineup and Helios rack, and Intel's Core Ultra Series 3 on 18A. What the three companies showed at CES 2026, and how their numbers and strategies diverge from the data center to the AI PC.
Kyoto University spinoff FLOSFIA completed verification of its 4-inch gallium oxide (α-Ga2O3) wafer process in December 2025. Substrate costs run up to 50 times below SiC, and the company puts its Baliga figure of merit at roughly 7,000 times silicon. Where next-generation power semiconductors actually stand.
Japan has committed more than ¥10 trillion (about $65 billion) in semiconductor support through fiscal 2030, aiming to draw ¥50 trillion in combined public and private investment. A look at the "crisis management investment" doctrine, Rapidus and 2nm, the equipment and materials sector, and the race with the US, China and Europe. An additional ¥631.5 billion for Rapidus was approved in April 2026.
Japanese startup blueqat unveiled Japan's first domestic semiconductor quantum computer at SEMICON Japan 2025. Leveraging existing chip manufacturing technology, the company targets 1 million qubits by 2030 and commercial deployment in 2026. With relaxed temperature requirements compared to superconducting systems, desktop-sized quantum computers may become reality.
Kyushu Electric's CEO predicts 20-30% power demand increase by 2034 due to TSMC semiconductor expansion and AI data center growth. Japan's 7th Basic Energy Plan emphasizes renewables and nuclear power to meet surging electricity needs.
According to the latest forecast by SEAJ (Semiconductor Equipment Association of Japan), sales of Japanese-made semiconductor manufacturing equipment are projected to reach ¥5.5 trillion in FY2026, up 12% YoY, exceeding ¥5 trillion for the first time in history. Expanding investment in advanced AI semiconductors is driving growth, with Japanese companies like Tokyo Electron expected to gain global market share.
In chip production, a single invisible particle can ruin a wafer. Daifuku is said to hold over half the world market for the systems that move those wafers. A look at the technology, and at the record ¥660.7 billion in revenue it posted for 2025.
