Infrastructure and AI are competing for attention on today’s Japan feeds. The government reissued a possible megaquake advisory for Hokkaido’s Sanriku coast — a stark reminder that Japan’s aging sewer network, now spanning 748km of dangerous pipes causing road cave-ins nationwide, shares the same underlying story of deferred maintenance and creeping risk. Meanwhile, Autodesk is embedding AI assistants across its core design tools and ServiceNow is partnering with Accenture on enterprise-wide agentic AI rollouts, suggesting AI adoption in Japanese manufacturing and enterprise is shifting from experimentation to execution.
