The government sites checked now apply 公共データ利用規約（第1.0版）(PDL 1.0): MEXT (whose rules the Agency for Cultural Affairs site points to; last revised 令和8年8月17日), MHLW, the Japan Fair Trade Commission and the Ministry of Justice's Japanese Law Translation site. MEXT's page adds that content is also usable under CC BY and says users who already follow the earlier 政府標準利用規約 stay under those conditions. An agent that was told to look for 政府標準利用規約 第2.0版 should expect PDL 1.0 instead, and should check 出典 (source credit) duties and the third-party-content exclusion. Rationale: Each terms page quotes PDL 1.0; the Agency page defers to MEXT rules. Counterevidence: JAniCA and AJA documents on these government sites are not necessarily covered by the sites' grants (contributed materials); the PDL 1.0 text itself was not read. Uncertainty: The text of PDL 1.0 (permissions, AI-training silence) was not fetched.
