Japan Ground Self-Defense Force Organization:

Operationally, the GSDF is organized into five regional armies directly subordinate to the Ground Staff Office. Each army is responsible for the geographical area by which it is designated. The Northern Army is located on Hokkaido, the Northeastern Army in Northern Honshu, the Eastern Army in the central Hohshu region, the Central Army in Western Honshu and Shikoku, and the Western Army in Kyushu and the Ryukyu Islands. The armies have both administrative and tactical functions. They are organized similarly to a U.S. Army Corps with a headquarters and assigned and attached units.

The divisions are grouped into three types: A, B, and C; the later is armored. A divisions consist of four infantry regiments, one artillery regiment, one tank regiment, one anti-tank unit, one reconnaissance unit, one engineer battalion, one signal battalion, an ordnance unit, a medical unit and an aviation unit and service troops. The Type B Divisions differ only in having three infantry regiments instead of four. The Type C division, 7th is very similar to the Type A but has self-propelled artillery and a larger allotment of APCs, providing transport for the engineers and signalers as well as the infantry.

The units are small; the infantry ‘regiment’ is really a battalion of four rifle companies and a heavy mortar company. Tank regiments consist of four tank squadrons each of which has two HQ tanks and three platoons of four tanks each. Thus the total strength of the Type A and C divisions is only 9,000 and of the Type B and is 7000: in NATO terms the division are really brigades.

The JGDSF consists of: 5 Army HQ (Regional Commands): Composite 1 bde; Armd Inf 8 div, 5 bde; Armd 1 div; Spec Ops 1 unit; AB 1 bdeArty 1 bde; 2 unit; Engr 4 bde; 1 unit; Hel 1 bde; Trg 2 bde; 2 regt; AD 2 bde; 4 gp;
