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.

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.

②After receipt of a warrant, a Japan Fair Trade Commission staff member may seize postal items, correspondence, or documents related to telegrams that are stored or possessed by persons handling communication affairs pursuant to the provisions of laws and regulations and do not fall under the provisions of the preceding paragraph, to the extent that there are sufficient grounds to suspect each of the items are related to a criminal case.

In this case, if it is found unnecessary to seize or seize by ordering records the relevant electronic or magnetic records, a Japan Fair Trade Commission staff member must rescind the request.

②The time period set forth in the preceding paragraph requesting not to erase may be extended not exceeding thirty days if necessary provided, however, that the total time period requesting not to erase may not exceed sixty days.

③If a request is made pursuant to the provisions of paragraph (1), and if it considers it necessary, a Japan Fair Trade Commission staff member may request that the matters concerning the relevant request are not divulged without good reason.
