Article 211-3Request for Preservation of Electronic or Magnetic Records of Communications History

①If it is necessary for carrying out the seizure or the seizure with an order to produce a copy of records, a Commission official may specify the necessary electronic or magnetic records from among the electronic or magnetic records of the sender, recipient, date and time, and other communications history, for telecommunications that are recorded in the course of business, and request in writing that a person engaged in the business of making equipment to be used for telecommunication available for other persons' communications or a person that has established equipment which is used for telecommunication and that is capable of intermediating the communications of unspecified or many persons for their own business not to erase the specified electronic or magnetic records during a fixed period of no longer than 30 days. In such a case, if the Commission official comes to find that it is no longer necessary to carry out the seizure or the seizure with an order to produce a copy of records concerning those electronic or magnetic records, the Commission official must withdraw that request.

②If it is particularly necessary, the period during which the request is made not to erase the records pursuant to the provisions of the preceding paragraph may be extended by a period of no longer than 30 days; provided however, that the period during which the request is made not to erase the records may not exceed 60 days in total.

③If it is necessary to do so in making a request under the provisions of paragraph (1), the Commission official may request that the particulars of that request not be divulged without reason.
