If a party to a case makes a prima facie showing of the following grounds, the court, at the petition of that party, may rule to limit the persons who may request access to the parts of the case records that contain the confidential information in question (meaning access to hard-copy case records or access to electronic or magnetic case records; the same applies in Article 133, paragraph (3)) (referred to below as "access to the confidential parts of the case records" in this Article) to the parties to the case:
次に掲げる事由につき疎明があった場合には、裁判所は、当該当事者の申立てにより、決定で、当該訴訟記録中当該秘密が記載され、又は記録された部分に係る訴訟記録の閲覧等（非電磁的訴訟記録の閲覧等又は電磁的訴訟記録の閲覧等をいう。第百三十三条第三項において同じ。）（以下この条において「秘密記載部分の閲覧等」という。）の請求をすることができる者を当事者に限ることができる。
a material piece of confidential information about the private life of a party appears in the case record, and a third party's access to the confidential parts of the case records would be likely to substantially interfere with that party's public life;
訴訟記録中に当事者の私生活についての重大な秘密が記載され、又は記録されており、かつ、第三者が秘密記載部分の閲覧等を行うことにより、その当事者が社会生活を営むのに著しい支障を生ずるおそれがあること。
a trade secret (meaning a trade secret as prescribed in Article 2, paragraph (6) of the Unfair Competition Prevention Act; the same applies below) being kept by a party to the case appears in the case records.
訴訟記録中に当事者が保有する営業秘密（不正競争防止法第二条第六項に規定する営業秘密をいう。以下同じ。）が記載され、又は記録されていること。
Once a petition as referred to in the preceding paragraph has been filed, a third party may not request access to the confidential parts of the case records until a judicial decision on the petition becomes final and binding.
前項の申立てがあったときは、その申立てについての裁判が確定するまで、第三者は、秘密記載部分の閲覧等の請求をすることができない。
A third party seeking access to the confidential parts of the case records may file a petition with the court of record to set aside the ruling stated in paragraph (1), on the grounds that any requirement prescribed in that paragraph has not been met or is no longer being met.
秘密記載部分の閲覧等の請求をしようとする第三者は、訴訟記録の存する裁判所に対し、第一項に規定する要件を欠くこと又はこれを欠くに至ったことを理由として、同項の決定の取消しの申立てをすることができる。
An immediate appeal may be filed against a judicial decision denying the petition stated in paragraph (1) and against a judicial decision on the petition stated in the preceding paragraph.
A judicial decision setting aside a ruling as referred to in paragraph (1) does not come into force unless it becomes final and binding.
第一項の決定を取り消す裁判は、確定しなければその効力を生じない。
If a petition under paragraph (1) (limited to a petition filed due to the existence of grounds stated in item (i) of that paragraph; the same applies in the following paragraph and paragraph (8)) has been filed and a third party intervenes in the litigation after its filing, the court clerk must notify the party who filed the petition of the intervention immediately after the intervention; provided, however, that this does not apply if the judicial decision denying the petition has become final and binding.
In a case as referred to in the main clause of the preceding paragraph, the court clerk may not permit the intervener to access the confidential parts of the case records about which the petition under paragraph (1) was filed, during the time that runs from the day of the notification under the provisions of that paragraph until the final day in the two-week period that follows; provided, however, that this does not apply if a petition as referred to in Article 133-2, paragraph (2) has been made.
前項本文の場合において、裁判所書記官は、同項の規定による通知があった日から二週間を経過する日までの間、その参加をした者に第一項の申立てに係る秘密記載部分の閲覧等をさせてはならない。ただし、第百三十三条の二第二項の申立てがされたときは、この限りでない。
The provisions of the preceding two paragraphs do not apply if all parties that have filed the petition under paragraph (1) consent to allow the intervener referred to in paragraph (6) to access the confidential parts of the case records about which the petition under paragraph (1) has been filed.
前二項の規定は、第六項の参加をした者に第一項の申立てに係る秘密記載部分の閲覧等をさせることについて同項の申立てをした当事者の全ての同意があるときは、適用しない。
If a petition under paragraph (1) (limited to one filed because the grounds stated in item (ii) of that paragraph exist; the same applies in the following paragraph) is filed, and if the use of a trade secret detailed in that petition for purposes other than conducting the suit, or the disclosure of that trade secret, would likely interfere with the party's business activities that are based on that trade secret, and the court finds it to be particularly necessary to do so in order to prevent this, the court may output the parts of the electronic or magnetic case records containing that trade secret in paper format or record them onto another recording medium, as well as taking measures to delete them from the electronic or magnetic case records or any other measures specified by the Rules of the Supreme Court as necessary and appropriate to securely manage the trade secret.
裁判所は、第一項の申立て（同項第二号に掲げる事由があることを理由とするものに限る。次項において同じ。）があった場合において、当該申立てに係る営業秘密がその訴訟の追行の目的以外の目的で使用され、又は当該営業秘密が開示されることにより、当該営業秘密に基づく当事者の事業活動に支障を生ずるおそれがあり、これを防止するため特に必要があると認めるときは、電磁的訴訟記録中当該営業秘密が記録された部分につき、その内容を書面に出力し、又はこれを他の記録媒体に記録するとともに、当該部分を電磁的訴訟記録から消去する措置その他の当該営業秘密の安全管理のために必要かつ適切なものとして最高裁判所規則で定める措置を講ずることができる。
If, after measures under the provisions of the preceding paragraph are taken to delete parts of the electronic or magnetic case records, a judicial decision denying the petition referred to in paragraph (1) becomes final and binding, or a judicial decision setting aside the decision concerning the petition becomes final and binding, the court clerk must record the part of the records containing the trade secret in the court's computer files.
