The book 'Cyber Attack: The Moment of the President's Decision' (author: Hisahiro Tatsushiro), published by Kantsu Inc. (Headquarters: Amagasaki City, Hyogo Prefecture; President & CEO: Hisahiro Tatsushiro; hereinafter 'Kantsu'), a company in the logistics and IT automation business, won the Grand Prize in the book category at the 'Cyber Security Award 2026' ceremony held on Monday, March 16, 2026.
This award, organized by the Digital Policy Forum (Chief Representative: Yasuhiko Taniwaki) and supported by the Ministry of Internal Affairs and Communications, the Ministry of Economy, Trade and Industry, and the National Police Agency, recognizes works that have contributed to improving cybersecurity literacy in Japan.
■ Background of the Award: Why was this record of 'decision' needed now?
In September 2024, a large-scale ransomware attack struck Kantsu Inc., a promoter of logistics DX. In a desperate crisis where all systems were down and shipping operations halted, how did top executive Hisahiro Tatsushiro make the decision for 'business continuity' and 'customer protection'?
This book is an unvarnished record of that raw behind-the-scenes story. Amidst a recent spate of corporate cyber damages, the book was highly praised by the judging committee for providing practical knowledge on 'what criteria managers should use for judgment in that moment,' going beyond technical countermeasures.
