78 years since the end of World War II, Japan has decided to take yet another step on the path toward becoming a “normal nation,” able to employ its military to boost its national interests like any other.

On December 22, the administration of Prime Minister Kishida Fumio revised guidelines on defense exports, allowing the transfer of finished lethal equipment, such as missiles, abroad for the first time.

This marks another major shift in the nation’s post-war policy of maintaining an exclusively defense-oriented policy, following last year’s historic decision to acquire – and possibly use – so-called “counterstrike capabilities” to strike back against enemy missile bases in the event of an armed attack on Japan.

Specifically, at the request of Washington, this time Tokyo has decided to export the Patriot Advanced Capability (PAC) system, or an air and missile defense (AMD) system, owned by Japanese Self-Defense Forces (JSDF), to the United States, where the interceptor system is licensed.

Demand for air defense systems, including Patriot surface-to-air missiles (SAMs) has significantly increased in countries such as Ukraine, Poland, Israel, and Taiwan and elsewhere in recent years. Accordingly, the U.S. has been drawing on its own missile inventory to provide those countries with missile interceptor systems. Exports from Japan will make up for its ally’s shortfall.
