Method (each step is stated by the cited source; this is not legal advice and not a prediction of any court outcome). Step 1: treat training/development and generation/use as two separate questions (EN overview; 考え方 chapter 5(1) vs 5(2)). Step 2: for training copies, ask whether the use is information analysis (情報解析), which the 考え方 reads, including AI training, as a non-enjoyment-purpose use under Article 30-4 (考え方 5(1)ア(ア); statute item 2 on e-Gov). Step 3: check whether an enjoyment purpose coexists, because a single enjoyment purpose defeats Article 30-4; the 考え方 gives intentional additional training meant to output the creative expression of the training works as an example, and the Checklist (1-1-1) adds RAG databases built to output works and small-scale additional training (e.g. LoRA) on one creator's works. Step 4: check the proviso, i.e. whether the use would unreasonably harm the owner's interests, judged by conflict with the work's market or potential market (考え方 5(1)エ(ア)); the Checklist (1-1-2, 1-1-3) names paid-for training datasets and circumvention of ID/password or robots.txt access limits as indicators. Step 5: if Article 30-4 does not apply, obtain permission (Checklist 1-1-4) and do not knowingly collect from pirate sites (1-1-5). Step 6: for generated outputs, apply the ordinary test: infringement needs similarity and reliance (依拠性) on an existing work; shared style or idea alone is not infringement (考え方 5(2), 5(1)エ(イ)). Step 7: record that the 考え方 states it is not legally binding, so cite it as an official view, and that the English translation of the Act is not an official text.

Rationale:
Every step is stated in the cited documents (quotes in evidence/quotes.jsonl for each underlying record). The ordering into one sequence is the collector's arrangement of the documents' own structure.

Counterevidence:
The 考え方 reports that a number of opinions (一定数) hold that substitution of a creator's demand by AI output could count under the proviso even without shared expression; the document itself leaves this open. No court ruling was found in the sources read.

Uncertainty:
Method was not executed by the collector (read-only desk review). Later revisions of the 考え方, court decisions after March 2024, and contract or terms-of-service limits were not checked.
