How often must the SOFA agreement be reviewed?

The Status of Forces Agreement (SOFA) typically does not mandate a specific timeline for regular reviews or revisions, allowing it to remain in effect indefinitely unless the parties agree to amend it or there are significant changes in circumstances that necessitate a review. This means that the SOFA can stay in place without a scheduled review process, allowing for flexibility in its application while maintaining the legal framework that governs the presence of foreign military forces in Japan.

By contrast, other options suggest specific timeframes for review, which is not a requirement under the SOFA framework. The absence of an established review schedule means that the agreement can adapt to changing contexts without the need for formal reassessment at prescribed intervals.
