During the occupation of Japan from 1945-1950, the 25th Infantry Division retained its triangular WWII organization of three infantry regiments. However, two of the infantry regiments were reduced to two battalions each and their supporting artillery battalions had only two firing batteries.

In 1949 a modification of the divisionís organization led to the adding of an anti-aircraft artillery battalion to the division artillery, a reduced strength tank battalion of one line company as well as additions and reconfigurations of several combat support and combat service support companies.

 It was in this configuration that the division entered the Korean War.
