This morning’s Japanese tech feeds are dominated by AI agents stepping out of demos and into production—TestMu’s pre-release safety verification, Funai’s SME platform PRIME, and Yayoi’s spec-less AI-native transformation all signal the same shift: trust and integration now matter more than raw model capability. Security lessons surface from an unlikely place (the Unko Museum breach), while developer tooling advances with VS Code 1.133 and React 19.3’s browser() API. MIT Technology Review adds a reality check on AI self-improvement and a glimpse at space travel concierges for the ultra-wealthy.
