Japan is preparing to require artificial intelligence companies to disclose the data used to train their AI models. This move comes as worries mount regarding the unauthorized use of copyrighted materials—text and images—in AI development. A draft code of conduct has been established to address these growing concerns about potential copyright infringement. The new regulations aim to promote transparency in AI training processes and protect intellectual property rights. By mandating disclosure, Japan hopes to foster a more responsible and ethical AI ecosystem. The specifics of the code, including enforcement mechanisms, are still being finalized. This development positions Japan as a leader in regulating the rapidly evolving field of artificial intelligence.
