What it requires
The EU AI Act is the world's first comprehensive horizontal AI law, applying a risk-based regime across all 27 member states — and to any company serving EU users. Prohibited-use bans already apply; high-risk system obligations (conformity assessment, technical documentation, human oversight) phase in through August 2, 2026.
Japan has confirmed an innovation-first, light-touch approach. The AI Promotion Act, passed in May 2025, is a promotion statute: it sets national principles and creates a Prime-Minister-chaired AI Strategy Headquarters, but imposes no prohibitions or monetary penalties on businesses. Companies are expected to voluntarily follow the METI/MIC AI Guidelines for Business (human-centricity, safety, fairness, transparency, accountability); the only real legal exposure for AI-related data handling comes via the existing APPI privacy regime, enforced by the Personal Information Protection Commission.
