“List of US Military Facilities/Zones [Exclusive Facilities] in Japan by Type”
objective
The purpose of this endeavor is to elucidate the locations and extent of US military bases in Japan. This endeavor aims to understand the areas influenced by these bases. Additionally, it underscores the significance of distinguishing between types of bases, such as Air Force, Navy, or Army bases, each serving different purposes and functions.
Understanding the usage patterns of these bases is equally imperative. Assessing the frequency of activities like training, military exercises, or logistical operations carried out within these bases helps evaluate their operational load and their impact on the surrounding regions. Moreover, it’s essential to consider the interaction between the bases and local residents. As the presence of military bases can significantly impact local communities, collaboration and coordination with residents become crucial.
Such information-gathering activities hold critical implications for national security. The locations and functions of these bases influence the country’s security strategy; hence, accurately grasping this information is pivotal. Ultimately, the collected information may potentially influence the decision-making of the government and associated organizations.
List of US Military Facilities in Japan
The information provided details the facilities and zones of the US Forces stationed within Japan. These locations serve various purposes, including communication, airfields, warehouses, training grounds, offices, ports, barracks, housing, and other functions. Spread across a wide geographical range from Hokkaido to Okinawa, these facilities and zones are geographically dispersed.
For instance, “Camp Chitose” in Chitose City, Hokkaido, serves as a communication facility, while “Misawa Air Base” in Misawa City, Aomori Prefecture, functions as an airfield. Facilities like the “Hachinohe Fuel Storage” spanning Hachinohe City in Aomori and Misawa City in Aomori and Rokkasho Village serve as warehouses. The “Misawa Range Complex” in Misawa City and Rokkasho Village is utilized as a training ground. Tokyo and Kanagawa also host numerous facilities with diverse purposes.
The total area of these facilities and zones amounts to 262,610 thousand square meters. Among these, 45 facilities/zones on the mainland (excluding Okinawa) cover 78,084 thousand square meters, while the 31 facilities/zones in Okinawa span 184,525 thousand square meters. This information is utilized to enhance a general understanding of the US Forces’ bases and activities in Japan.
Through this data, a clearer understanding emerges of how the US Forces’ bases and facilities exist within Japan, shedding light on their impact on local communities and national security.
