Summary In April, 2024, an article titled "The Current State of National Security and Digital Platform Regulation," authored by Professor Maiko Ichihara of the Graduate School of Law, was published in Horitsu Jiho. In this article, Professor Ichihara analyzes how national security threats are triggered on digital platforms and examines digital platform regulations for ensuring security, using the United States as a case study. Professor Ichihara points out that each digital platform is formed based on the attention economy model, wherein emotionally charged content is placed in prominent locations, making it easier for emotional disinformation to spread and for populist politicians to mobilize the masses. She also mentions that with the advent of social media, the impact of digital platforms on international politics has dramatically increased, and explains the threats of influence operations conducted through digital platforms. Furthermore, although it is difficult to assess the appropriateness of temporary regulations, she emphasizes the necessity of unified regulations, including for U.S. platform providers, to stabilize security and international relations.
