Four signals this morning: deep capital keeps flowing into frontier tech — roughly ¥60 billion toward fusion power, plus a Series B for voice AI — while the security side keeps flashing. Cisco’s tests show LLM guardrails soften under repeated prompts, and the Linux kernel just dropped 432 CVEs at once. The takeaway for me is that Japan’s builders are betting aggressively on long-horizon hardware and applied AI, even as the foundational software under everything else is fraying faster than anyone can patch. Worth watching whether the funding surge outruns the hardening work.

• Starlight Engine Raises ¥60.6 Billion Led by Global Brain to Promote Fusion Power Demonstration “FAST” (BRIDGE)
  On July 15, Starlight Engine — which is pushing forward a tokamak-based fusion power demonstration project — announced that it has raised a total of ¥60.6 billion through a third-party share allotment, its first outside funding round. The round was led by Global Brain, with participation from Mitsui Fudosan, KDDI Open Innovation Fund V, the Tokyu-CNST GB Innovation Fund, Fukoku CVC, Sony Financial Ventures, Airbus Ventures and Kyoto University.

• RevComm, a Voice Analysis AI Company, Raises ¥3.35 Billion in Series B Led by SMBC Edge (BRIDGE)
  On July 22, RevComm — the operator of the voice analysis AI "MiiTel" — announced the first close of its Series B at ¥3.35 billion, taking total funding to ¥8.6 billion. Equity was led by SMBC Edge (SMBC-GB Growth Fund No. 1 Investment Limited Partnership), with WiL, KDDI, Shinsei Venture Partners and Salesforce Ventures also participating; debt financing came from Fukuoka Bank and SDF Capital’s Startup Debt Fund.

• AIは何度も話しかけると“落ちる”　ガードレール突破検証で分かった最も安全なLLM (＠IT Security&Trustフォーラム 最新記事一覧 (In Japanese Language))
  A Cisco test found that even flagship LLMs like Claude, ChatGPT and Gemini — which carry strong guardrails — see their defenses weaken when an attacker simply keeps prompts coming across multiple turns. The piece asks why models still drift toward unintended behavior, and how attackers are using that softness to slip past protections.

• Linuxカーネルで432件のCVEが一斉公開　「重要な脆弱性だけ直す」運用は限界か (＠IT Security&Trustフォーラム 最新記事一覧 (In Japanese Language))
  An unusually large batch of 432 CVE IDs was published against the Linux kernel in a short window, and security teams are taking notice. The traditional playbook — triage each vulnerability and prioritize the consequential ones — is starting to buckle under sheer volume, and the piece asks what kind of operational model actually fits a "mass CVE" era.
