The Minister for Internal Affairs and Communications may designate, as a large-scale specified telecommunications service provider, a specified telecommunications service provider that provides a specified telecommunications service that falls under all of the following items and for which it is found that there is a particularly high need for expediting the implementation procedures for measures for preventing transmission of violating information and for transparency of the implementation status of transmission prevention measures with regard to the dissemination of information through specified telecommunications pertaining to its use (hereinafter referred to as a "large-scale specified telecommunications service").
総務大臣は、次の各号のいずれにも該当する特定電気通信役務であって、その利用に係る特定電気通信による情報の流通について侵害情報送信防止措置の実施手続の迅速化及び送信防止措置の実施状況の透明化を図る必要性が特に高いと認められるもの（以下「大規模特定電気通信役務」という。）を提供する特定電気通信役務提供者を、大規模特定電気通信役務提供者として指定することができる。
that specified telecommunications service falls under any of the following;
当該特定電気通信役務が次のいずれかに該当すること。
the average, over the period specified by Order of the Ministry of Internal Affairs and Communications, of the number of persons who became senders in a month by using that specified telecommunications service (excluding persons presumed to be located outside Japan; the same applies in (b)) and persons specified by Order of the Ministry of Internal Affairs and Communications as equivalent thereto (hereinafter referred to as the "average monthly number of senders" in this Article and Article 24, paragraph (2)) exceeds the number specified by Order of the Ministry of Internal Affairs and Communications according to the type of specified telecommunications service;
the average, over the period specified by Order of the Ministry of Internal Affairs and Communications, of the total number of persons who became senders in a month by using that specified telecommunications service (hereinafter referred to as the "average monthly total number of senders" in this Article and Article 24, paragraph (2)) exceeds the number specified by Order of the Ministry of Internal Affairs and Communications according to the type of specified telecommunications service.
it is technically possible to take measures for preventing transmission of violating information (limited to those taken to the extent necessary for preventing the transmission of violating information to unspecified persons; the same applies hereinafter) in light of the general nature of that specified telecommunications service;
当該特定電気通信役務の一般的な性質に照らして侵害情報送信防止措置（侵害情報の不特定の者に対する送信を防止するために必要な限度において行われるものに限る。以下同じ。）を講ずることが技術的に可能であること。
that specified telecommunications service is other than one specified by Order of the Ministry of Internal Affairs and Communications as a specified telecommunications service with little risk of violation of rights occurring due to the dissemination of information through specified telecommunications pertaining to its use.
If the Minister for Internal Affairs and Communications finds that the grounds for the designation under the provisions of the preceding paragraph no longer exist with regard to a large-scale specified telecommunications service provider, the Minister must, without delay, rescind the designation.
総務大臣は、大規模特定電気通信役務提供者について前項の規定による指定の理由がなくなったと認めるときは、遅滞なく、その指定を解除しなければならない。
To the extent necessary for the designation under the provisions of paragraph (1) and the rescission of designation under the provisions of the preceding paragraph, the Minister for Internal Affairs and Communications may, as provided by Order of the Ministry of Internal Affairs and Communications, have a specified telecommunications service provider report the average monthly number of senders and the average monthly total number of senders of the specified telecommunications service it provides.
総務大臣は、第一項の規定による指定及び前項の規定による指定の解除に必要な限度において、総務省令で定めるところにより、特定電気通信役務提供者に対し、その提供する特定電気通信役務の平均月間発信者数及び平均月間延べ発信者数を報告させることができる。
If the Minister for Internal Affairs and Communications finds that it is difficult to ascertain the average monthly number of senders or the average monthly total number of senders of a specified telecommunications service provided by a specified telecommunications service provider by means of the collection of reports under the provisions of the preceding paragraph, the Minister may estimate that average monthly number of senders or average monthly total number of senders by a reasonable method specified by Order of the Ministry of Internal Affairs and Communications, and make the designation under the provisions of paragraph (1) and the rescission of designation under the provisions of paragraph (2).
総務大臣は、前項の規定による報告の徴収によっては特定電気通信役務提供者の提供する特定電気通信役務の平均月間発信者数又は平均月間延べ発信者数を把握することが困難であると認めるときは、当該平均月間発信者数又は平均月間延べ発信者数を総務省令で定める合理的な方法により推計して、第一項の規定による指定及び第二項の規定による指定の解除を行うことができる。
