Denso proposed a tender offer for Rohm worth up to 1.3 trillion yen (about $8.2 billion), then withdrew it in April 2026 after Rohm's special committee declined to endorse the deal. Consolidation has shifted to a Rohm-Toshiba-Mitsubishi Electric alliance. Here is the competitive picture against Infineon, onsemi, and China's fast-rising players.
Japan's DNP invests in Rapidus to accelerate EUV photomask development for 2nm chips. Explore how EUV photomasks have become a bottleneck in advanced semiconductor manufacturing, Japan's dominant position with HOYA and Toppan, and the roadmap toward 1.4nm and beyond.
Japan reveals the full picture of its Rapidus investment scheme: becoming top shareholder with just 10% voting rights, holding golden shares with veto power, and a mechanism to seize majority control if finances deteriorate. We compare Japan's $19B commitment with the US CHIPS Act and EU Chips Act, and examine whether Rapidus can realistically mass-produce 2nm chips by 2027.
Hitachi and Tokyo Institute of Science have achieved a 280x improvement in coherence time and 99.1% gate fidelity using ordinary silicon — no special isotopes needed. Unlike IBM and Google's superconducting approach, Hitachi's silicon-based quantum computer leverages existing chip-making infrastructure. With cloud access planned for 2027, Japan is carving its own path in the global quantum race.
The explosive growth of AI data centers is creating a golden age for power electronics. With tens of thousands of GPUs fluctuating power equivalent to a nuclear plant by over 50%, Japanese makers like Mitsubishi Electric, Fuji Electric, and Toshiba see a massive opportunity. Includes US and Europe comparisons.
As AI's explosive growth makes chip power consumption a critical global issue, Japan's next-generation chip technologies are drawing worldwide attention. Tohoku University's MRAM memory reduces power consumption to 1/100th of conventional chips, while Saga University's diamond semiconductors — called the "ultimate semiconductor material" — advance toward space and 6G applications. We report on Japan's technological edge and the intensifying competition with the US and China.
Canon is launching its first new KrF lithography system in 14 years, boosting throughput by 30% to challenge ASML's dominance. With a global NAND shortage creating opportunity and a $330 million factory expansion underway, Canon's multi-front strategy, including nanoimprint lithography and ArF dry re-entry, signals Japan's semiconductor equipment counterattack.
Rapidus CEO Atsuyoshi Koike unveiled the world's first 600mm square glass substrate RDL interposer at SEMICON Japan 2025. With 10x production efficiency over conventional 300mm wafers, the technology targets AI chip cost reduction. A detailed comparison with TSMC's CoWoS and Intel's Foveros, plus Rapidus's 2028 mass production roadmap for Japan's semiconductor packaging strategy.
Japan's Kioxia is set for consecutive record-breaking years, with revenue exceeding $14 billion for the first time. NAND production capacity for 2026 is already "sold out" as AI data center demand far outpaces supply. From a rocky IPO to the world's best-performing stock of 2025 with a 540% gain, we explore Kioxia's remarkable turnaround and what it means for Japan's semiconductor renaissance.
Kagawa Prefecture becomes Japan's first local government to sign a partnership with NVIDIA. From GPU data center development to AI talent cultivation with University of Tokyo's Professor Yutaka Matsuo, discover how this small prefecture is pioneering a bold "Sovereign AI" strategy for regional revitalization.
Japan's Rapidus targets full-scale 2nm chip production by FY2028 in Hokkaido. From prototype success to mass production roadmap, TSMC & Samsung competition, $19 billion in government support, and Japan's semiconductor revival strategy: a comprehensive report.
