Japan AI Act
The purest 'light-touch by design' national law among major economies, betting that guidance plus reputational levers suffice. Its December 2025 R&D guideline shows how soft obligations get operational teeth without formal sanctions.
What it is
Japan's first AI law is promotion-oriented: it establishes an AI Strategic Headquarters under the Cabinet, a national AI Basic Plan, and cooperation duties for businesses — with no penalties, relying on government ability to name uncooperative actors.
Core provisions effective 2025; AI Strategic Headquarters guideline issued December 2025.
