**第一項**  特定労務管理対象機関の管理者は、当該特定労務管理対象機関に勤務する医師のうち、その予定されている労働時間の状況が厚生労働省令で定める要件に該当する者（以下この条及び次条において「特定対象医師」という。）に対し、当該特定対象医師ごとに厚生労働省令で定める業務の開始から厚生労働省令で定める時間を経過するまでに、厚生労働省令で定めるところにより、継続した休息時間を確保しなければならない。ただし、当該業務の開始から厚生労働省令で定める時間を経過するまでに、厚生労働省令で定めるところにより特定対象医師を宿日直勤務に従事させる場合は、この限りでない。

The administrator of an institution subject to specified labor management must, for those physicians working at the institution subject to specified labor management whose scheduled working hours status falls under the requirements specified by an Order of the Ministry of Health, Labour and Welfare (hereinafter referred to as "specified target physicians" in this Article and the following Article), ensure a continuous rest period, pursuant to an Order of the Ministry of Health, Labour and Welfare, by the time a period specified by an Order of the Ministry of Health, Labour and Welfare has elapsed from the start of the work specified by an Order of the Ministry of Health, Labour and Welfare for each specified target physician. However, this does not apply where the specified target physician is made to engage in night or day duty, pursuant to an Order of the Ministry of Health, Labour and Welfare, by the time a period specified by an Order of the Ministry of Health, Labour and Welfare has elapsed from the start of that work.

**第二項**  特定労務管理対象機関の管理者が、厚生労働省令で定めるやむを得ない理由により、前項の規定により確保することとした休息時間（以下この項において「休息予定時間」という。）中に特定対象医師を労働させる必要がある場合は、前項の規定にかかわらず、当該休息予定時間中に当該特定対象医師を労働させることができる。この場合においては、厚生労働省令で定めるところにより、当該休息予定時間の終了後に、当該特定対象医師に対し、当該休息予定時間中に労働をさせた時間に相当する時間の休息時間を確保しなければならない。
<sup>suppl-3231-205/art-123/par-2 · https://japanlaw.org/en/medical-care-act/suppl-3231-205/art-123/par-2 · https://japanlaw.org/l/323AC0000000205/suppl-3231-205/art-123/par-2</sup>
In the case where the administrator of an institution subject to specified labor management needs, for an unavoidable reason specified by an Order of the Ministry of Health, Labour and Welfare, to have a specified target physician work during the rest period determined to be ensured pursuant to the preceding paragraph (hereinafter referred to as the "scheduled rest period" in this paragraph), the administrator may, notwithstanding the preceding paragraph, have the specified target physician work during the scheduled rest period. In this case, the administrator must ensure, after the end of the scheduled rest period, a rest period for the specified target physician equivalent to the time that the physician worked during the scheduled rest period, pursuant to an Order of the Ministry of Health, Labour and Welfare.

In the case referred to in the proviso to paragraph (1), where the administrator of the relevant institution subject to specified labor management has had the specified target physician work during the night or day duty, the administrator must give consideration to ensuring the necessary rest period for the specified target physician after the night or day duty, pursuant to an Order of the Ministry of Health, Labour and Welfare.

**第四項**  災害その他避けることのできない事由によつて、臨時の必要がある場合においては、特定労務管理対象機関の管理者は、当該特定労務管理対象機関の所在地の都道府県知事の許可を受けて、その必要の限度において第一項本文及び第二項後段の規定による休息時間の確保を行わないことができる。ただし、事態急迫のために当該都道府県知事の許可を受ける暇がない場合においては、事後に遅滞なく届け出なければならない。
<sup>suppl-3231-205/art-123/par-4 · https://japanlaw.org/en/medical-care-act/suppl-3231-205/art-123/par-4 · https://japanlaw.org/l/323AC0000000205/suppl-3231-205/art-123/par-4</sup>
In the event of a temporary need arising from a disaster or other unavoidable cause, the administrator of an institution subject to specified labor management may, with the permission of the prefectural governor of the area in which the institution subject to specified labor management is situated, refrain from ensuring the rest periods under the main clause of paragraph (1) and the second sentence of paragraph (2) to the extent of that need. However, where there is no time to obtain the permission of that prefectural governor due to the urgency of the situation, the administrator must submit a notification afterwards without delay.

**第五項**  前項ただし書の規定による届出があつた場合において、都道府県知事が第一項本文及び第二項後段の規定による休息時間の確保を行わなかつたことを不適当と認めるときは、その後に必要な休息時間を確保すべきことを、命ずることができる。

In the case where a notification has been made pursuant to the proviso to the preceding paragraph, if the prefectural governor finds it inappropriate that the rest periods under the main clause of paragraph (1) and the second sentence of paragraph (2) were not ensured, the governor may order that the necessary rest period be ensured thereafter.
