Article 102

①When necessary in the investigation of a criminal case, a Japan Fair Trade Commission staff member may conduct an on-site inspection, search, seizure, or seizure with ordering records ('seizure with ordering records' as used in this Act means having a custodian of the electronic or magnetic records or other persons with the authority to use electronic or magnetic records copy the necessary electronic or magnetic records onto the recording medium or print them out, and seizing the recording medium; the same applies hereinafter) by virtue of a warrant issued in advance by a judge of the district court or summary court having jurisdiction over the location of the Japan Fair Trade Commission.

②When the object to be seized is a computer, and with regard to a recording medium connected via telecommunication lines to the computer, it may be reasonably supposed that the recording medium is used to retain electronic or magnetic records, which have been made or altered using the computer or which may be altered or erased using the computer, the Japan Fair Trade Commission may seize the computer or other recording medium after the electronic or magnetic records have been copied onto the computer or other recording medium.

③In cases under the preceding paragraphs requiring urgency, a Japan Fair Trade Commission staff member may take the measures under the preceding paragraphs by virtue of a warrant issued in advance by a judge of the district court or the summary court having jurisdiction over the location of the site to be inspected, the site, body, or object to be searched, the object to be seized, or the person to have the electronic or magnetic record recorded or printed.

④When a Japan Fair Trade Commission staff member requests a warrant provided for in paragraph (1) or the preceding paragraph (excluding Article 114-3, paragraphs (4) and (5), hereinafter referred to in this Chapter as a "warrant"), the Japan Fair Trade Commission staff member must submit materials that confirm the existence of a criminal case.

⑤If a request provided in the preceding paragraph is made, the judge of the district court or the summary court must issue a warrant to the Japan Fair Trade Commission staff member with the judge's name and seal affixed thereto, and the following information entered thereon: the site to be inspected; the site, body or object to be searched; or the object to be seized; the electronic or magnetic records to be recorded or printed; the person to be made to record or print the electronic or magnetic records, and the government position and name of the person making the request; the warrant's valid period; the fact that the inspection, search or seizure may not be initiated and the warrant must be returned after the expiration of the valid period; the date of issuance of the warrant; and the name of the court to which the judge belongs. In this case, if the name of the suspect in a criminal case (for a corporation, this means its name) or the fact of a criminal offense is known, these matters must also be written.

⑥In cases under paragraph (2), other than the matters provided by the preceding paragraph, the scope of the recording medium requiring duplication of the relevant electronic or magnetic records connected to the computer to seize via telecommunication lines must be written on the warrant.

⑦A Japan Fair Trade Commission staff member may deliver a warrant to another Japan Fair Trade Commission staff member and have that staff member conduct the on-site inspection, search, seizure, or seizure with ordering records.
