The short answer

How copyright applies to AI art differs by country, by how it is used and by each case, so there is no single answer. As a creator, the basics are: do not make the AI copy other people's works or existing characters, check the terms of the service you use, and when unsure, check official sources or a qualified professional.

Does AI art have copyright?

It depends on the country, how the image was made and how much a person contributed, so there is no single answer.

How AI-generated images are treated is still being discussed in many countries and regions, and some public bodies have published their views. Even among images made with AI, the outcome may differ depending on how they were made and how much a person was involved. This guide does not state conclusions; it introduces points creators should check. For accurate information, check materials from public bodies such as your country's copyright office (in Japan, the Agency for Cultural Affairs) or consult a qualified legal professional.

What should you watch out for when creating?

The most important thing is not to make the AI directly imitate other people's works, existing characters or real people.

Do not add a specific artist's name or work title to copy their style exactly
Do not publish existing anime, game or manga characters as your own work
Do not create images of real people using their photos or names without their consent
Do not use someone else's image as the source for img2img to make a nearly identical picture
Do not put logos, trademarks or work titles inside the image

Rinka's tips

Designing and drawing your own original character reduces the worry about resemblance
If a result looks like an existing work or character, it is safest not to publish it
Keeping the prompt and settings you used helps if you ever need to explain how it was made

What should you check before publishing?

Check three things: it does not resemble existing works, it follows the terms, and whether there are rules for labeling AI work.

Steps to check before publishing

Look carefully for resemblance to existing works, characters or logos
Read the terms of the generation service you used for conditions on publishing and use
Check whether the site or social network you post to has rules for AI labels or tags
Make sure you did not use someone else's work as the source image
If anything is unclear, hold off on publishing, or check official sources or a qualified professional

[Pre-publish check] Not similar to existing works or characters / No real people depicted / Read the generation service's terms / Checked the posting site's AI labeling rules

[Record] Date made / Service used / Prompt / Source image used? (if yes, is it my own image?)

What if it ends up looking like someone else's work?

If it is not yet published, do not use it; if it is, consider taking it down, and consult a professional when unsure.

AI generates images based on tendencies in what it learned, so it can produce something close to an existing work even unintentionally. The safest choice for an image that feels similar is not to publish or use it. If you have already published it, consider removing it and consult a professional about specific steps.

Common worries and how to think about them

Here are general cautions and where to check. The conclusion differs from case to case.

Common worry	What to be careful about	Where to check
I want to put an artist's name in the prompt	It may imitate a specific artist's style	Safest not to; also check the terms
I want to draw my favorite character	Publishing existing characters can raise rights issues	The rights holder's guidelines and official information
I want to turn a photo into anime style	Other people's photos need consent and rights	Use your own photo, with consent
I want to sell it or use it for work	Conditions are set by the service's terms and contracts	The terms of use, a professional
