Practice Relating to Rule 127. Respect for Convictions and Religious Practices of Persons Deprived of Their Liberty
Japan’s Law concerning the Treatment of Prisoners of War and Other Detainees in Armed Attack Situations (2004) states:
The worship and other religious acts that a detainee performs individually in the prisoner-of-war camp shall not be prohibited nor restricted; provided, however, that this shall not apply to the case in which there is a risk of causing a hindrance to either the maintenance of discipline and order or the management and administration of the prisoner-of-war camp.
(1) The prisoner-of-war camp commander shall make efforts to make available the opportunities for detainees to participate in religious ceremonies, such as sermons and worship, presided over by chaplains and other religious leaders whenever a detainee hopes to do within the prisoner-of-war camp.
(2) In cases where there is a risk of causing a hindrance to either the maintenance of discipline and order or the management and administration of the prisoner-of-war camp, the prisoner-of-war camp commander may refuse to permit a detainee to participate in the religious ceremonies prescribed in the preceding paragraph.
