Which of the following must U.S. military personnel adhere to when practicing their religion in Japan?

U.S. military personnel must adhere to regional customs and laws when practicing their religion in Japan because they are subject to both the legal framework established by the Status of Forces Agreement (SOFA) and the host nation's regulations. This means that while they have the right to practice their religion freely, they need to do so in a manner that respects and complies with local customs and laws. This adherence is essential for maintaining good relations between U.S. forces and the Japanese community, ensuring that their religious practices do not infringe on local norms or legal statutes.

While American customs, international laws, and local community beliefs may play roles in shaping the understanding of religious practices, the primary obligation for U.S. military personnel in Japan is to respect the regional customs and laws, which guide the integration of their religious practices within the local context. This approach fosters mutual respect and understanding, which are vital components of the bilateral relationship between the United States and Japan.
