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:
The term "whistleblowing" as used in this Act means a report made by a person stated in the following items with no wrongful purpose such as a purpose of acquiring a wrongful gain or causing damage to others, that a reportable fact that has occurred, or is about to occur, concerning a business operator provided for in the respective items (meaning a corporation or other organization and an individual who engages in business; the same applies below) (referred to below as "recipient of services"), or its officer (meaning a corporate director, executive officer, accounting advisor, corporate auditor, director, inspector, and liquidator, and any other person who is engaged in the management of the corporation (excluding a financial auditor) under the provisions of laws and regulations (meaning laws as well as orders based on them; the same applies below); the same applies below), employee, agent, or other persons engaged in the business of the recipient of services, to the recipient of services or a person designated by the recipient of services in advance (referred to as "recipient of services or other designated person"), to an administrative body with the authority to impose a disposition (meaning an order, revocation, and other acts involving the exercise of public authority; the same applies below) or issue a recommendation, etc. (meaning a recommendation and other acts which are not dispositions; the same applies below) with regard to the reportable fact, or a person designated by the administrative body in advance (referred to as "administrative body or other designated person" in paragraph (1), item (ii) of the following Article and Article 6, paragraph (1), item (ii)), or to a person to whom reporting the reportable fact is considered necessary in order to prevent the their occurrence or the spread of damage caused by them (including persons who suffered or are likely to suffer damage because of the reportable fact, but excluding persons who are likely to cause harm to the competitive position or other legitimate interests of the recipient of services; the same applies in paragraph (1), item (iii) of the following Article and Article 6, paragraph (1), item (iii)).
Japanese Law Translation, Ministry of Justice
Translates the law as amended by Act No. 62 of 2025 (令和七年法律第六十二号)
An amending law usually leaves every article's number alone: a new article takes a branch number such as Article 32-2, and a repealed one leaves 削除 (Deleted) at its number. Sometimes it moves a run of articles to new numbers instead — 繰下げ (moving them down) to make room, or 繰上げ (moving them up) to close a gap. The words of a moved article need not change, but books, court decisions and contracts written before cite it by its old number. This site marks a moved article with the number it had before the amendment: Act No. 53 of 2023 (令和五年法律第五十三号) makes Article 55 of the Act on Land and Building Leases (借地借家法) Article 58.
