The assets on this site are produced using image generation AI. "Is it safe to use AI-generated images at work?" is a fair question, so here is what is currently established, what tends to cause problems in practice, and what we do about it.
Where the rules stand
In Japan, the Legal System Subcommittee of the Copyright Subdivision of the Council for Cultural Affairs published "General Understanding on AI and Copyright in Japan" in March 2024, released by the Agency for Cultural Affairs. A checklist and guidance document followed in July 2024. These are currently the most widely referenced official treatments of the relationship between generative AI and copyright.
Case law is still thin, and some questions remain unsettled. This article does not offer a legal conclusion. If a decision matters, consult those documents or a specialist.
In practice, what matters is what the image contains
Whether an image was generated by AI matters less, in day-to-day practice, than what is actually in it. An image that resembles an existing character or a real person, contains a shape close to a company logo or trademark, or copies a particular artist's style wholesale will cause trouble regardless of how it was produced.
Put the other way round: the checks are much the same as for any other asset. Look at the image before you use it and judge whether anything in it might touch someone else's rights.
What we do
- Avoid problems at generation time: prompts are designed to avoid existing characters, public figures, brand logos, trademarks, and imitation of a specific artist's style. Text and logo-like shapes are explicitly excluded during generation
- Human review before publication: generated images are never published automatically. Every image is checked individually in our admin screen, and only approved images go live. Automatic approval based on quality scores is disabled, because we did not consider the scoring reliable enough
- Withdraw anything questionable: if a concern surfaces after publication, we can take the asset down from the admin screen
Do you need to disclose that it is AI-generated?
Some platforms ask you to label AI-generated content when you post. Where that applies, follow their instructions. Every asset on this site is AI-generated, so you can declare it without further checking.
Usage terms
Our assets are free for both personal and commercial use. No attribution is required and editing is allowed. We prohibit redistributing or selling the assets themselves, registering them as trademarks, using them for purposes that violate public order and morals, and bulk collection as AI training data.
As stated in our disclaimer, we accept no liability for damages arising from use of the assets. For anything critical, please satisfy yourself about the content before using it.
If you notice a problem
If you believe an asset resembles an existing work, please tell us through the contact form. We will look into it and take the asset down if we judge that necessary. Reports like these do a great deal to keep the library safe and usable.
