Where this applies
Japan. The overview says material autonomously generated by AI, including with only simple prompts, is not a creative expression and is not considered a copyrighted work, while any additions or corrections made by humans to AI-generated material that can be considered creative expressions are generally considered copyrighted works. It states that the General Understanding is not legally binding; it is the subcommittee's view of current law.
What this means
In the largest anime-producing country, rights attach to what people add and correct. For studios that own their characters, that keeps an artist's hand in the finished frames.
What it does not yet show
Non-binding guidance for one country; courts may decide otherwise, and it does not measure studio practice.
What you can check
Open the Japan Copyright Office's overview "General Understanding on AI and Copyright in Japan" and find "additions or corrections made by humans".
Does it change the assessment?
No. The impact index is never moved by a single event. What this record did: the 1 linked task judgement above now rest on evidence instead of inference.
