Shigeru Kitamura, CEO of Kitamura Economic Security Inc, released his latest book Invisible War: The Geopolitics of Intelligence, Spheres of Influence, and Economic Security through Bungeishunju on June 19, 2026.

The author, having served as Secretary General of the National Security Secretariat and having stood at the forefront of national security and intelligence, examines an era of “invisible war,” in which U.S.-China confrontation, regional conflicts, economic security, cyberspace, AI, and other forces are intricately intertwined. This volume discusses the role of intelligence in contemporary warfare, great-power competition over spheres of influence, the economic security preparedness required of companies, and the relationship between technology and sovereignty, and presents how Japan is to survive strategically in an age of great competition.
