GitHub's Universe keynote landed with a clear message — the coding assistant is becoming a team of agents that picks its own models — and Japan's manufacturers answered in kind, with Murata putting ¥1 trillion behind the capacitors AI data centers will need and Fujifilm quintupling tape output for the archives all that AI will generate. On security, the news cuts both ways: GitHub's own data says the old 'critical means fix it now' reflex is drowning teams, while nine in ten developers now expect cars to be ransomware targets within three years. And in classrooms, Google is quietly putting hundreds of textbooks inside Gemini Notebook for free. The thread I keep seeing: AI is moving from demo to infrastructure, and the bill — in chips, in storage, in new attack surfaces — is coming due in very concrete places.

Topics in this Spud’s Japan View

1. GitHub、AIモデルを自動選択・連携するCopilot Fusionを一般提供、資料とエージェントの作業をまとめるCopilot Projectsをパブリックプレビューに ——GitHub Universe 2026で自動化・コードレビュー・セキュリティも更新
   (GitHub brings Copilot Fusion to general availability and Copilot Projects to public preview at GitHub Universe 2026)
   (gihyo.jp)
   GitHub used its Universe 2026 conference on October 28–29 to make Copilot Fusion generally available, letting the assistant automatically select and coordinate multiple AI models for a task, and to open a public preview of Copilot Projects, which gathers documents and agents' work in one place on the desktop Copilot app. The announcements also covered updates to automation, code review, and security across the platform.
2. 村田製、MLCCに1兆円投資 AIは「創業以来最大のチャンス」
   (Murata to invest ¥1 trillion in MLCCs, calling AI 'the biggest opportunity since our founding')
   (EE Times Japan)
   Murata Manufacturing will invest about ¥1 trillion over five years from fiscal 2026 to 2030 in multilayer ceramic capacitors (MLCCs), betting on surging demand from AI data centers. The company plans to more than double MLCC sales by fiscal 2030 versus fiscal 2025 and expand production capacity by roughly 20% a year in fiscal 2027–2028, calling AI its biggest opportunity since the company was founded.
3. 富士フイルム、データ保存需要で磁気テープを5倍に増産
   (Fujifilm to quintuple magnetic tape production on data-storage demand)
   (EE Times Japan)
   Fujifilm announced in October 2026 that it will expand manufacturing capacity for data-storage magnetic tape to about five times its current level, investing roughly ¥10 billion in equipment and staffing. The move answers growing demand for data archiving as generative AI produces ever-larger volumes of data that need cheap, long-term storage.
4. 「3年以内に車はランサムウェアに狙われる」 9割の開発者が回答
   (Nine in ten developers say cars will be ransomware targets within three years)
   (ITmedia AIT Security)
   A survey of developers found that about 90% believe cars will be targeted by cyberattacks within three years, naming cybersecurity vulnerabilities as the biggest risk as software-defined vehicles (SDVs) spread. The finding reflects a growing worry that connected cars — which now receive regular software updates like phones — are becoming an attractive target for ransomware operators.
5. もう「CVSSで重大→修正急務」は限界 「即対応」脆弱性を9割減らすGitHub推奨の優先順位付け基準
   ('Critical by CVSS, fix it now' has hit its limit: GitHub's prioritization standard cuts must-fix-now vulnerabilities by 90%)
   (ITmedia AIT Security)
   GitHub's report on 2025 open-source vulnerability trends, drawn from its Advisory Database, argues that treating every CVSS-critical flaw as an emergency is no longer workable. Its recommended prioritization standard cuts the number of vulnerabilities demanding immediate action by about 90%, letting teams focus on the flaws attackers are actually likely to exploit.
6. Gemini Notebook、米国・インドの一部教科書を無料で追加可能に
   (Gemini Notebook adds hundreds of textbooks for free in the US and India)
   (gihyo.jp)
   Google announced on October 29 that its AI research and study service Gemini Notebook (formerly NotebookLM) now lets users add hundreds of textbooks for free in the United States and India. The move puts full course materials inside the AI study tool, letting students query, summarize, and cross-reference their textbooks directly.
