The was a field army of the Imperial Japanese Army (IJA) during World War II. It was originally the 14th Army, formed on November 6, 1941 for the upcoming invasion of the Philippines. It was reorganized in the Philippines on July 28, 1944, when Allied landings were considered imminent. The Fourteenth Area Army was formed by reinforcing and renaming the . (An IJA "area army" was equivalent to a field army in other militaries, while an IJA "army" was a smaller, corps-level formation.) History The Japanese 14th Army was formed on November 6, 1941, under the Southern Expeditionary Army Group for the specific task of invading and occupying the Philippines. It initially consisted of the IJA 16th Division, 48th Division, 56th Division, and 65th Independent Mixed Infantry Brigade. In January 1942, the 48th Division was detached and reassigned to the Japanese Sixteenth Army for the invasion of the Netherlands East Indies, and was replaced with the Fourth Division. As the army was still fighting in the Philippines, its commanding officer, Lieutenant General Masaharu Homma, requested more reinforcements. The 10th Independent Garrison was sent to the Philippines as was the 21st Division Infantry Group, and the First Field Artillery Headquarters to command the field artillery units. The Fourth and Seventh Tank Regiments were part of the 14th Army, as well as the First, Eighth, and 16th Field Artillery Regiments and the 9th Independent Field Artillery Battalion. This army was responsible for the Bataan Death March after the surrender of US and Filipino forces in Bataan, and the 65th Independent Brigade was also accused of the Mariveles Massacre. The 14th Army came under the direct control of Imperial General Headquarters in June, 1942; however, the Southern Expeditionary Army Group in Saigon continued to issue orders, at times in conflict with those received from Tokyo, and the 14th's commanding officer was plagued by insubordination from junior officers who used the situation to issue orders without his approval, or to countermand orders with which they did not agree. In August 1942, Homma was replaced by Lieutenant General Shizuichi Tanaka. In July 1942 the 4th Division came under control of the 14th Army, as did the 30th Division, which was assigned to the defense of Mindanao. As the war situation continued to deteriorate for Japan, and Allied forces prepared to invade the Philippines, the 14th Army restructured its independent infantry brigades and reserves to form
