This morning’s Japan is building outward in every direction at once. Sakana AI is finally going mobile, Sony’s researchers are measuring exactly how leaky image models are about famous characters, and the cloud giants are reshuffling shares as AI spending hits a record pace. Down in the hardware layer, Mitsubishi Electric is squeezing cleaner signals out of gallium nitride, Omron is betting big on made-in-India blood-pressure monitors, and Hokkaido is turning a single chip fab into a whole R&D town. The common thread: Japanese tech isn’t just shipping products this week — it’s laying down the factories, the rules, and the infrastructure the next decade will run on.

Topics in this Spud’s Japan View

1. Sakana AI「初のモバイルアプリ」開発中　テスターも募集
   (Sakana AI Developing Its First Mobile App, Recruiting Testers)
   (ITmedia AI+)
   Sakana AI has begun developing its first mobile app, tentatively called the ‘Sakana AI App,’ and is recruiting testers to try it. The Tokyo-based startup, known for its evolutionary approach to model building and its AI Scientist research, has so far reached users mainly through web demos and APIs — a phone app would put its models directly in people’s pockets. Details on features and launch timing are still thin, but the tester call suggests a public release is not far off.
2. 画像生成AIは既存のキャラクターをどれくらい出力する？　ソニーAIなどが14モデルを調査
   (How Much Do Image-Generation AIs Reproduce Existing Characters? Sony AI and Others Survey 14 Models)
   (ITmedia AI+)
   Sony AI researchers and collaborators have published a technical report testing how often 14 image-generation models reproduce recognizable existing characters and intellectual property, and how well each model’s safety guardrails prevent it. The study, ‘Evaluating Intellectual Property Guardrails of Generative Image Models,’ probes a question every AI-image vendor now faces: models trained on the open web can summon near-copies of famous characters on demand, and the guardrails meant to stop that vary widely in effectiveness. The findings land as studios and platforms keep tightening the rules on AI-generated likenesses.
3. クラウドインフラのシェア、AWSが26％に後退　Google Cloudは16％に上昇　市場全体は過去最大の高成長率へ　2026年第3四半期調査
   (Cloud Infrastructure Share: AWS Slips to 26%, Google Cloud Rises to 16% as the Overall Market Hits Record Growth in Q3 2026)
   (ITmedia AI+)
   Synergy Research Group reports that the global cloud infrastructure market grew at its fastest rate ever in the third quarter of 2026, with Amazon Web Services’ share slipping to 26% while Google Cloud climbed to 16%. AWS remains the clear leader, but the gap is narrowing as AI workloads reshape where enterprises spend. The record growth rate suggests the AI-driven infrastructure boom is still accelerating rather than leveling off, with all three hyperscalers benefiting even as their relative shares shift.
4. 高周波トランジスタにおけるGaN on GaN技術の優位性、三菱電機が実証
   (Mitsubishi Electric Demonstrates the Advantage of GaN-on-GaN Technology in High-Frequency Transistors)
   (Monoist)
   Mitsubishi Electric has demonstrated that gallium-nitride-on-gallium-nitride (GaN on GaN) technology gives high-frequency transistors a clear advantage over the usual GaN-on-silicon-carbide approach. By growing the GaN epitaxial layer directly on a GaN substrate, the company traced the cause of frequency dispersion to crystal defects and showed the effect can be sharply suppressed. The result matters for the high-frequency devices inside 5G/6G base stations, radar, and satellite links, where cleaner signals at higher frequencies translate directly into performance.
5. オムロン初のインド生産拠点が稼働、2028年には生産能力10倍に
   (Omron’s First India Production Base Begins Operating, Capacity to Grow Tenfold by 2028)
   (Monoist)
   Omron Healthcare has started mass production of blood-pressure monitors for the Indian market at its first production base in India, in Tamil Nadu, and plans to grow capacity tenfold by 2028. The plant is the Omron group’s first in India, and it anchors a push to secure stable supply as cardiovascular disease detection becomes a bigger public-health priority there. For Omron, local production also hedges against the supply-chain and tariff friction that has complicated cross-border medical-device shipments.
6. 北海道を最先端技術の集積地に　千歳市内に先端半導体R＆D拠点を新たに形成へ
   (Making Hokkaido a Hub of Cutting-Edge Technology: New Advanced Semiconductor R&D Base to Be Built in Chitose)
   (MONOist Embedded)
   Mitsubishi Estate, the city of Chitose, and NTT Docomo Business have signed an agreement to build a new advanced-semiconductor research and development hub, tentatively called ‘Chitose Technology Frontier,’ in the Chitose Mimi World industrial park in Hokkaido. The project aims to turn the area around Rapidus’s new fab into a broader cluster of semiconductor R&D and innovation, pulling suppliers, researchers, and startups north. It is the latest sign that Hokkaido’s chip ambitions extend well beyond a single factory.
