A report on Japan’s online games sector says every surveyed developer is now using generative AI, suggesting the technology has become mainstream in that part of the industry. The finding matters because it points to a sharp rise in adoption while also highlighting a growing gap between developers’ use of AI tools and players’ concerns, especially around copyright and the risk of games becoming more alike.

The figures come from the 2026 JOGA Online Game Market Research Report, previewed by Famitsu, and cover Japanese online game developers rather than the whole games industry. Google’s Gemini was used by 94 percent of respondents, Anthropic’s Claude by 84 percent, and GitHub Copilot by 76 percent, with common uses focused on user preference analysis and behaviour prediction rather than generating art or audio. The article compares this with a 2025 Tokyo Game Show survey, where 50 percent of developers reported using generative AI, and notes that Japanese and some other Asian developers appear more open to AI than many Western studios and audiences.
