There are various fields of work - from flight, air control and maintenance, to logistic support.

The mission of JASDF is to prevent an incursion by enemy aircraft or the landing of a foreign enemy. In order to carry this out, fighter aircraft units, aircraft control and warning groups, anti-aircraft troops are disposed throughout the nation, and other units and organizations such as depots, schools, and hospitals, are engaged in the support of these. Furthermore, efforts to maintain and increase peace and stability of the international community, are carried out through the dispatch of aid in the event of a major disaster and through international peace cooperation works. In this way, for JASDF to follow through in a highly diverse area, the work of a Self-Defense official also covers a wide range of fields, from aviation and those relating to defense equipment such as "air control", "interception air control", "equipment", "anti-aircraft artillery", to logistic support such as "information", "weather", "communications electronics", "programming", "transportation", and "facilities".
