beyond what is set forth in the preceding two items, if the opposite party is a person who conducts business in Japan (including any foreign company (which refers to a foreign company as prescribed in Article 2, item (ii) of the Companies Act (Act No. 86 of 2005)) which continuously conducts transactions in Japan) and if the petition relates to the opposite party's business in Japan.
前二号に掲げるもののほか、日本において事業を行う者（日本において取引を継続してする外国会社（会社法（平成十七年法律第八十六号）第二条第二号に規定する外国会社をいう。）を含む。）を相手方とする場合において、申立てが当該相手方の日本における業務に関するものであるとき。
Notwithstanding the preceding paragraph, parties may establish, by agreement, the country in which they are permitted to file a petition for a sender identification information disclosure order with the courts.
The agreement as referred to in the preceding paragraph is not valid unless it is executed by means of a written document.
前項の合意は、書面でしなければ、その効力を生じない。
If electronic or magnetic records (meaning records used in computer data processing which are created in electronic form, magnetic form, or any other form that is impossible to recognize through the human senses alone) in which the content of the agreement is recorded are used to execute the agreement as referred to in paragraph (2), the agreement is deemed to have been executed by means of a written document, and the provisions of the preceding paragraph apply.
The agreement under paragraph (2) that a petition for a sender identification information disclosure order may be filed only with the courts of a foreign country, may not be invoked if those courts are unable to exercise jurisdiction by law or in fact.
Even when the Japanese courts have jurisdiction over a petition for a sender identification information disclosure order pursuant to the provisions of the preceding respective paragraphs (except when a petition is filed based on an agreement under paragraph (2) that only permits a petition to be filed with the Japanese courts), the court may dismiss the whole or part of a petition without prejudice if it finds that there are special circumstances under which the Japanese courts were to conduct a trial and reach a judicial decision in the action, it would be inequitable to either party or prevent a fair and speedy trial, in consideration of the nature of the case, the degree of burden that the opposite party would have to bear in pursuing the proceedings, the location of evidence, and other circumstances.
Whether the Japanese courts have jurisdiction is determined on the basis of the time at which a petition for a sender identification information disclosure order is filed.
日本の裁判所の管轄権は、発信者情報開示命令の申立てがあった時を標準として定める。
