General Understanding on AI and Copyright in Japan
This document provides an overview of the Legal System Subcommittee's views on the interpretation of the current Japanese Copyright Act as applied to artificial intelligence and copyright. It outlines basic concepts regarding the AI development and training stage, the generation and utilization stage, copyright infringement criteria, and the copyrightability of AI-generated materials. The text is intended to offer a tentative consensus and general understanding without being legally binding.
Summary and content fields are drawn from the document text and are pending editorial review.
Who issued it
Who it governs
AI developers, users, creators, and legal researchers should read this to understand the Japanese government's tentative consensus on how existing copyright law applies to artificial intelligence.
What the document contains
The document covers the legal interpretation of the Japanese Copyright Act regarding the collection of training data for AI development, copyright infringement criteria during the generation and utilization stage, and the requirements for determining the copyrightability of AI-generated materials.
It does not provide binding legal assessments for specific generative AI technologies, nor does it address moral rights or detailed enforcement penalties beyond standard judicial remedies.
- The General Understanding outlines the subcommittee's interpretation of the current Japanese Copyright Act regarding AI and copyright but is not legally binding.
- Under Article 30-4, exploiting copyrighted works for non-enjoyment purposes such as AI development and training is generally permitted without permission, provided it does not unreasonably prejudice copyright holders' interests.
- Fine-tuning or retrieval-augmented generation (RAG) that aims to output copyrighted expressions may fail the non-enjoyment purpose requirement and require authorization.
- AI-generated materials autonomously produced without human creative contribution are not protected by copyright.
- Using AI as a tool with specific prompts, iterative corrections, and creative intention can make the human user an author of a copyrightable work.
