'AI citation' is a phrase that sounds quietly resonant but in reality involves broad questions spanning copyright, academic ethics, and generative AI training methods. What is needed now is not a definitive declaration but clarifying the outlines. In the U.S., the accumulation of Copyright Office reports, court cases, and university disclosure guidelines shifts focus from how AI-written content is treated to how AI use is recorded.[1][2][3][10] AI has become more like air than software, making invisibility untenable.

The U.S. Copyright Office published a pre-release version of 'Copyright and Artificial Intelligence Part 3: Generative AI Training Report,' clarifying connections between AI training and copyright.[1] Reuters reported on June 24, 2025, Anthropic’s key victory in an AI authorship copyright case, and on June 5, 2026, detailed legal issues facing AI companies.[2][3] What becomes apparent is that AI training and use are not automatically illegal or legal—a troublesome but obvious reality.

Fair use, explained by Web担当者Forum, hinges on four factors: purpose and character of use, nature of the copyrighted work, amount used, and market impact.[5] The law provides no simple black-and-white answers; conclusions fluctuate depending on factor weighting, complicating generative AI training debates. When models absorb vast copyrighted works and generate new output, the issue extends beyond 'amount copied' to a wide framework including transformation and possible market substitution.[1][5][6][7]

Quinn Emanuel’s Japan office notes generative AI’s broad applications have sparked many copyright lawsuits alleging infringement during AI training.[6] The issue is industry-wide, not limited to a single company or product, resembling a quiet courtroom behind the scenes assessing how much copyrighted work AI may borrow and if fair use applies.

However, the Japanese sense of 'AI citation' does not directly correspond to U.S. fair use. Citation typically involves partial use of others' work with source indication, but generative AI features multiple layers: data ingestion during training, reproduction at output, and disclosure in research or writing.[1][5][10][11] Though a single word is used, the legal problems are multiple; failing to separate which 'citation' is meant leads the discussion into a fog.

University of Utah's Office of Artificial Intelligence highlights the importance of documenting AI use when it directly affects manuscript generation, editing, or data analysis in research and scholarship.[10] When AI only sparks ideas and humans do writing and analysis, many publishers do not necessarily require disclosure.[10] The focus is on how much AI contributed to the output rather than mere usage.

This distinction is technically interesting as large language models probabilistically generate different outputs rather than return identical answers each time. Hence, differentiating between AI assisting notes, producing substantial text, or re-expressing copyrighted works is necessary.[10][11][12][13] Transparency does not call for full disclosure of model internals but at least an ethical record of where AI influenced human work.

Currently confirmable is that U.S. Copyright Office summaries, Reuters’ litigation reports, law firm insights, and university disclosure guidance each illuminate the same landscape from distinct perspectives.[1][2][3][6] Whether AI 'citation' generally qualifies as fair use, or how it might be treated legally in various jurisdictions, cannot be conclusively determined from available information.[1][2][3][5] Especially when using this term in Japan, caution is essential. Before finding comfort in the convenience of the term, clarifying which usage layer is under discussion is necessary.

This subject will endure beyond flashy new functions as AI quietly infiltrates texts, gradually shifting boundaries among source indication, training, and disclosure. Future developments to track include cumulative U.S. court rulings, further clarifications from the Copyright Office, and how AI use documentation becomes standard in education and publishing.[1][2][3][10] Though no firm answer yet exists, one thing is clear: 'citation' in the AI age may be moving away from mere text cut-and-paste toward transparency of involvement.
