It is sufficient for a notice or demand to shareholders to be sent by a stock company to the addresses of relevant shareholders stated or recorded in the shareholder register (or, if relevant shareholders notify relevant stock company of a different place or contact address for the receipt of notices or demands, to that place or contact address).
The notices or demand in the preceding paragraph are deemed to have arrived at the time when that notice or demand should normally have arrived.
前項の通知又は催告は、その通知又は催告が通常到達すべきであった時に、到達したものとみなす。
Article 126, paragraph (3)
If a share is co-owned by two or more persons, the co-owners must specify one person to receive the notices or demand sent by the stock company to shareholders and notify relevant stock company of the name of that person. In these cases, that person is deemed to be the shareholder and the provisions of the preceding two paragraphs apply.
If there is no notice by co-owners under the provisions of the preceding paragraph, it is sufficient for a notice or demand sent by a stock company to the co-owners of the shareholders if it is sent to one of them.
The provisions of each of the preceding two paragraphs apply mutatis mutandis to cases where, when the notice referred to in Article 299, paragraph (1) (including the case where it is applied mutatis mutandis in Article 325) is given, a document is delivered to shareholders or matters to be stated in relevant document are provided to shareholders by electronic or magnetic means. In these cases, the phrase "to have arrived" in paragraph (2) is deemed to be replaced with "to have been effected by delivery of relevant documents or the provision of relevant matters by electronic or magnetic means".
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.
