Japan has formally asked OpenAI to stop using copyrighted anime in its AI-generated content.

The request comes after the launch of Sora 2 in October, which can create realistic 20-second videos. Many clips featuring well-known characters from One Piece, Pokémon, Demon Slayer, and other major anime appeared online without authorization.

According to the Japanese Intellectual Property Strategy Headquarters, these AI creations infringe on the rights of anime creators.

Minister of State Minoru Kiuchi emphasized the importance of protecting Japanese cultural exports, calling anime and manga “cultural assets that captivate the world.” He highlighted the government’s challenge: supporting AI innovation while preserving the integrity of Japan’s creative works.

Other officials, including Digital Minister Masaaki Taira, urged companies to voluntarily comply with copyright rules. While the AI Promotion Act does not currently impose penalties, it allows the government to investigate harmful AI use, signaling potential future regulations if companies ignore these warnings.

OpenAI CEO Sam Altman responded by promising to introduce safeguards, giving rights holders more control over how their characters appear in AI-generated videos. Altman also recognized Japan’s unique cultural impact, noting the “deep connection” between fans and Japanese media. Despite these measures, many creators and fans in Japan feel that AI is already exploiting their work without proper consent.

Japanese companies have been clear about their stance. Nintendo, for example, reaffirmed it will take action against unauthorized use of its characters in AI content. The concern echoes similar legal battles in the West, where studios are suing AI companies for copyright violations.

This situation highlights a global debate over AI, creativity, and intellectual property. For Japan, protecting anime and manga is about more than law—it’s about safeguarding the artistry and storytelling that have made its culture beloved worldwide.

In my view, Japan’s firm stance is necessary to ensure that AI doesn’t undermine creative industries. Innovation is important, but it shouldn’t come at the cost of respect for the artists who built these worlds. What do you think about AI using copyrighted media? Share your thoughts in the comments.
