Not fully current. The translation page header shows 'Last Version： Act No. 52 of 2021' and states that only the original Japanese texts have legal effect. The e-Gov revision list for the Act includes 令和八年法律第四十八号 with enforcement dates 2026-06-24 and 2029-06-23, and other later amendments. For Article 30-4 itself, the English wording read (general permission, information-analysis item, computer-data-processing item, and the proviso on unreasonable prejudice to the copyright owner) matches the Japanese text read on e-Gov in substance. Agents should cite the Japanese e-Gov text and use the translation only for orientation. Rationale: Header text and revision list were both read; the Agency site describes 令和8年法律第48号 as concerning a new record-performance right (search result of the Agency page, not fetched in full), so Article 30-4 is likely unchanged (that summary is a search-result description of the Agency page and was not fetched in full). Counterevidence: The e-Gov revision list returned no entry flagged CurrentEnforced, which is inconsistent with a 2026-06-24 revision marked PreviousEnforced; revision status flags are unreliable as read. Uncertainty: Whether any amendment after Act No. 52 of 2021 changed Article 30-4 or 47-5 was not checked clause by clause.
