How frequently is the SOFA agreement reviewed or renegotiated?

The Status of Forces Agreement (SOFA) between the United States and Japan does not have a fixed schedule for review or renegotiation. This means that while the agreement can be renegotiated as necessary based on evolving circumstances, it does not require a review at regular intervals such as annually, every five years, or solely in response to significant incidents. This flexible approach allows both nations to address issues and make adjustments to the agreement when required, reflecting changing political, security, and economic contexts. Such flexibility is crucial in international relations, as it acknowledges that diplomatic needs may arise unexpectedly and require timely action to ensure mutual interests are safeguarded and adapted to current realities.
