Coming into force施行
The day a law or an amendment starts to apply. It is often months or years after promulgation, so that people have time to prepare. The Ministry of Justice's English usually says a law "comes into force" or "comes into effect", and sometimes calls the day its "enforcement date". Its "enforcement" more often means the word's other sense, carrying a law out, as in an Order for Enforcement (施行令), the Cabinet Order (政令) that sets out the details for carrying out an Act.
The Ministry of Justice's English of this passage has a slip, so the English shown is this site's correction of it. The Ministry printed:
A person seeking the certification referred to in the preceding paragraph must apply to the Personal Information Protection Commission as prescribed by Cabinet Order.
