This roundup spans a curious mix: Tokyo’s markets are quietly expanding with new ETF and PRO Market listings, while Chiba prefecture still grapples with the aftermath of last week’s torrential rains. On the tech front, the government has kicked off trials for a domestically built AI system — a notable push for sovereign capability — and Stripe’s acquisition of OpenRouter signals big money flowing into model-agnostic infrastructure. But the standout story might be Accenture’s survey: only 57% of Japanese workers feel AI boosts productivity versus 81% globally. That gap isn’t about tools; it’s about how organizations deploy them.
