The convocation notice for a meeting must indicate the subject matter of the meeting and the outline of the proposal and be sent to each unit owner (excluding those who do not hold voting rights) at least one week prior to the date of the meeting; provided, however that this period may be extended by the bylaws.
集会の招集の通知は、会日より少なくとも一週間前に、会議の目的たる事項及び議案の要領を示して、各区分所有者（議決権を有しないものを除く。）に発しなければならない。ただし、この期間は、規約で伸長することができる。
If an exclusively-owned area is under the co-ownership of multiple persons, it is sufficient to send the notice under the preceding paragraph to the person whom it has been decided will exercise their voting rights (or to one of the co-owners, if there is no such person) pursuant to the provisions of Article 40.
It is sufficient to send the notice under paragraph (1) to the place where the unit owner has notified the manager that they will receive notices, and if the unit owner has not notified the manager of such a place, to the place where the exclusively-owned area owned by the unit owner is located. In such a case, the notice under that paragraph is deemed to have arrived at the time when the notice should have normally arrived.
If a special provision is provided in the bylaws, the notice under paragraph (1) may be given to a unit owner whose address is in the building, or to a unit owner who has not notified the manager of the place where they are to receive notices under the preceding paragraph, by posting the notice somewhere conspicuous within the building. In such a case, the notice under paragraph (1) is deemed to have arrived at the time when the notice is posted.
