Generative AI is already in the routine of 85.8% of Japanese developers surveyed by CESA (Computer Entertainment Supplier's Association). In the previous year's survey, that share was 51%. The figure comes from a preview of the industry report and shifts the AI debate inside studios.
The numbers are in the preliminary summary of the developer employment and career survey tied to CEDEC, Japan's main game development conference. The full report is due in December. Coverage by Kotaku and IT Home points back to CESA's own research page.
What the survey measured
There were 1,349 individual responses. Among people already using the tools, 63% said they use them every day and 22.8% only occasionally. Another 8.6% said their company already has some guidance on the technology. CESA's definition of generative AI includes examples such as ChatGPT, GitHub Copilot, and image or asset generation services.
Usage is not limited to art. It covers administrative work and programming assistance as well as visual material. Of the respondents, 837 said the technology expands creative room and 738 said it lowers the technical barrier. Many also pointed to shorter production time and lower cost.
Players barely show up in the upside
The contrast is at the other end of the ledger: only 147 people said generative AI actually improved the experience of the person playing. The perceived gain is concentrated in the internal process, not the finished product.
A second cut, taken among CESA member companies, stops the 85.8% figure from being read as a portrait of every studio. In that group, 74% already have a formal generative AI policy. Companies not using it (27) and companies using it in some form (26) were almost even. Only 12 companies said they use the technology for visual assets; use in story, localization, testing, and programming was even smaller.
Why the number needs care
The main sample is people, not companies. Several professionals from the same studio can report the same policy, which inflates the sense of widespread adoption. CESA did not publish a studio-level breakdown in this preview.
Context matters too. In recent weeks Level-5, the studio behind Dark Cloud and Professor Layton, faced suspicion of AI-generated images in a presentation, and games such as Crazy Taxi: World Tour have already drawn player pushback over AI disclosures. Adoption in Japan is rising, but the company survey shows that internal policy and use in final art are not moving at the same speed as everyday chatbot and copilot use.
