Japan

Act on Access to Information Held by Administrative Organs

Act No. 42 of 1999

Japan's national access law. Anyone may file, from anywhere, for a ¥300 fee — but responses issue in Japanese.

The clock

30 calendar days

Disclosure decision within 30 days of the request, extendable by 30; very large requests may be answered in instalments.

In September 2020 the Defense Minister ordered SDF units to record and report unidentified aerial objects and preserve imagery — that instruction created the record class worth asking for.

Reading the statute itself

The text of this one is not reproduced here: foreign legislation is published under its own country’s copyright rules, so it is linked instead. Everything on this page — the deadline, the appeal path, the fee standard — is Aletheca’s summary of that text, and the official source is one click away.

If they refuse

Appeal deadline
90 days — three months to seek administrative review
Appeal route
Administrative review referred to the Information Disclosure and Personal Information Protection Review Board, or suit in district court.
Litigation
District court; venue rules were loosened specifically for disclosure suits.

Fees and expedition

Fee-waiver standard

¥300 application fee per request, plus copying charges.

Aletheca argues this on every request it files here. A service that publishes every page it receives, free, to a public archive has an unusually strong showing — considerably stronger than a private requester’s.

Exemptions it allows
