Japan-U.S. Security Treaty sparks debate over base usage

Discussions regarding the Japan-U.S. Security Treaty highlight legal and strategic tensions concerning the use of military bases in Japan. Under Article 6 of the treaty, the United States is permitted to use facilities and areas within Japanese territory to contribute to the security of Japan and the maintenance of peace in the Far East.

Critics point to a discrepancy between this intended purpose and current military deployments. For instance, assets stationed in Japan, such as the aircraft carrier George Washington and F-35B units from Iwakuni, have been deployed to the Middle East. This movement has raised concerns regarding the potential reduction of deterrent capabilities within the Far East.

Furthermore, the treaty's framework allows for a “total base system,” where the U.S. maintains broad rights to utilize locations across Japan without specific geographic restrictions. This has led to a significant concentration of military presence in Okinawa, which hosts approximately 70.3% of the total area of U.S. exclusive military facilities in Japan, despite the prefecture representing only 0.6% of the country's landmass.
