I noticed this week’s Japanese tech news centers on data governance and the space economy. NTT docomo’s admission of sharing customer data with Amazon without consent raises fresh questions about privacy in telecom–retail partnerships. Meanwhile, the Gyazo breach—leaking 23.6 million user accounts and 490 million image metadata records—shows that image-sharing platforms face the same hardening needs as any cloud service. On the more optimistic side, Japan’s space ecosystem keeps maturing: JAXA, Dentsu, and a village are using satellite data to predict cabbage shipments and cut food waste, and professionals from telecom/infrastructure are finding fresh careers in space traffic management.
