Japan’s industrial and tech scene this week is all about dual pressures: supply chain resilience and AI ambition. FamilyMart is doubling down on bio-based plastic in its bags — a direct nod to the Middle East situation tightening petrochemical supply chains — while Mitsubishi Electric quietly drops news of a next-gen SiC power semiconductor that cuts on-resistance by a quarter. On the policy front, Tokyo is making a play for access to the AI model Mythos for cyber defense, while keeping doors open with Google, Microsoft, and OpenAI. And in a more open gesture, the University of Tokyo’s Matsuo Lab has released its LLM fundamentals course materials for free — a reminder that Japan is both consuming and contributing to the global AI knowledge base.
