The largest of the three services of the JSDF, the Ground Self-Defense Force operates under the command of the chief of the ground staff, based in the city of Ichikawa, east of Tokyo. Although allotted 180,000 slots for uniformed personnel, in 1992 the force was maintained at about 86 percent of that level (with approximately 156,000 personnel) because of funding constraints. The number of uniformed personnel is insufficient to enable an immediate shift onto emergency footing. Instead, the ratio of officers to enlisted personnel is high, requiring augmentation by reserves or volunteers in times of crisis. In 1992, however, GSDF reserve personnel, numbering 46,000, had received little professional training. Intended to deter attack, repulse a small invasion, or provide a holding action until reinforced by United States or Allied armed forces, the ground element is neither equipped nor staffed to offer more than a show of conventional defense by itself. Anti-tank artillery, ground-to-sea firepower and mobility were improved and surface-to-ship missiles were acquired in the Mid-Term Defense Estimate completed in FY 1990.

The GSDF consists of one armored division, nine infantry divisions (each with three or four infantry regiments, each the size of a British infantry battalion), one airborne brigade, two combined brigades, four training brigades, one artillery brigade with two groups, two air defense brigades with three groups, one helicopter brigade with twenty-four squadrons and two anti-tank helicopter platoons.

5th Infantry Regiment is with 9th Division, 6th Inf Regt. with 5th Brigade, 10th Infantry Regiment with 11th Div., 11th Infantry Regiment with 7th Division, and 25th and 26th Infantry Regiments with 2nd Division.

In 1989, basic training for lower-secondary and upper-secondary academy graduates began in the training brigade and lasted approximately three months. Specialized enlisted and non-commissioned officer (NCO) candidate courses were available in branch schools and qualified NCOs could enter an eight-to-twelve-week second lieutenant candidate program. Senior NCOs and graduates of an eighty-week NCO pilot course were eligible to enter officer candidate schools, as were graduates of the National Defense Academy at Yokosuka and graduates of four-year all universities. Advanced technical, flight, medical and command and staff officer courses were also run by the GSDF. Like the maritime and air forces, the GSDF ran a youth cadet program offering technical training to lower-secondary school graduates below military age in return for a promise of enlistment.

Because of population density on the Japanese islands, only limited areas were available for large-scale training, and, even in these areas, noise restrictions were a problem. The GSDF tried to adapt to these conditions by conducting command post exercises and map maneuvers and by using simulators and other training devices.
