Asia-Pacific Security System Project

Research Theme

This research project aims to examine the past, present, and future security systems of the Asia-Pacific region, with a focus on the U.S. Pacific Command.

It is well known that the U.S. military consists of four services: the Army, Navy, Air Force, and Marine Corps. However, actual combat units are organized into nine ""unified commands."" Six of these nine are regional, and three are functional. The ""U.S. Pacific Command (PACOM)"" is responsible for the Asia-Pacific region. PACOM is said to be the largest of the nine unified commands, comprising 370,000 personnel.

Until now, the presence of U.S. Forces Japan (USFJ) and U.S. Forces Korea (USFK) has drawn attention when considering the security of East Asia, including Japan. However, the USFJ Headquarters and USFK Headquarters are, so to speak, merely field offices of the Pacific Command. In the event of an emergency, it is the PACOM Headquarters, located on Oahu, Hawaii, USA, that commands operations. Symbolically speaking, while the USFJ Commander is a Lieutenant General, the PACOM Commander is an Admiral. The PACOM Commander reports only to the U.S. President and the Secretary of Defense, thus holding immense authority over security in the Asia-Pacific region.

Despite the undeniable importance of the Pacific Command when considering Asia-Pacific security, academic research focusing directly on PACOM is scarce, both in the United States and in other countries. China's maritime expansion and North Korea's nuclear and missile programs continue to destabilize security in the Asia-Pacific region. It is also a region where cyberattacks frequently occur. Security concerning the Pacific must also take into account the presence of Pacific island nations, which consist of islands scattered across the region.

This research project is an attempt to re-examine Asia-Pacific security from a multi-dimensional and multi-faceted perspective. With the appointment of Admiral Harry Harris, a Japanese American, as the PACOM Commander, new developments are unfolding, and we aim to conduct research that also benefits such practical applications. We intend to delve into the fundamental question of what a unified command is within the U.S. military structure, tracing its history of establishment, clarifying its current organizational structure, and providing an overview of its current activities. Furthermore, we will explore how operations would unfold in an emergency in the Asia-Pacific region and what kind of cooperation would take place with U.S. allies such as Japan, South Korea, Singapore, and the Philippines.
