How frequently is the Okinawa SOFA reviewed or renegotiated?

The Okinawa Status of Forces Agreement (SOFA) is typically reviewed or renegotiated in response to significant incidents that may affect the presence of U.S. military forces in Japan or the local community's perspective on their presence. This process allows the agreement to be adapted as necessary to address changing circumstances or concerns, ensuring that it remains relevant and effective in managing the relationship between the U.S. military and Japan.

The frequency of these reviews or negotiations is not set on a specific timeline, such as annually or every decade, but instead is usually triggered by important events, including political, social, or security issues that arise in relation to the U.S. military presence. Options that suggest a rigid schedule do not accurately reflect the reality of how the agreement is managed and updated, as flexibility is key to addressing the dynamic nature of international relations.
