Japan's AI Strategy Revised: Security Fears & Sovereignty

The Japanese government has approved a hurried revision of its national artificial intelligence strategy. This comes amid security fears and the rapid evolution of AI technology. The new policy aims to establish "AI sovereignty" and counter new risks. It outlines a review of existing systems and AI-related legislation. There will also be strengthened cooperation with foreign agencies. This revision happened quickly, just six months after the original plan, due to powerful new AI models like Anthropic’s Claude Mythos. Officials state these technologies make cyberattack threats more tangible. The government also wants to bolster its domestic ability to research and operate AI. This reduces overdependence on specific countries or companies. The plan identifies a "path to victory" by focusing on vertical AI, for fields like medicine, and physical AI, for robotics and autonomous driving. The government projects a public-private investment of 23.1 trillion yen in vertical AI and 10.5 trillion yen in physical AI by fiscal 2040. This is a significant increase from current figures, as a Stanford University study ranked Japan 14th in private AI investment for 2025. This strategy matters because it shows how quickly governments are reacting to the changing landscape of AI and its potential impact on national security and economic independence.
