Japan’s industrial and tech agenda is moving on multiple fronts today. The government is quietly re-embracing nuclear — for the first time since Fukushima, numerical reactor targets are on the table. Meanwhile, major firms are deepening AI ties with global leaders (Hitachi and Anthropic) and squeezing efficiency with AI surrogate models that cut simulation times from 45 minutes to 5. Manufacturers are passing costs downstream to stay alive in a tariff-disrupted environment. There’s a coherent story here: Japan is building a new industrial playbook, and AI + energy are the twin pillars.
