The China Expeditionary Army (支那派遣軍 Shina haken gun) was an army group of the Imperial Japanese Army during the Second Sino-Japanese War and World War II. It was responsible for all military operations in China, and at its peak had over 1 million soldiers under its command. In military literature, it is often referred to by the initials CEA.[1]


After the Lugou Bridge Incident, the Japanese China Garrison Army was reinforced with the Shanghai Expeditionary Army. This force was further supplemented by the Japanese Tenth Army, and marched inland from Shanghai to occupy Hangzhou. In October 1937, this force was renamed the Japanese Central China Area Army. After the fall of Nanking, the Central China Expeditionary Army was formed. On September 12, 1939 by Army Order 362, the China Expeditionary Army was formed with the merger of the Central China Expeditionary Army with the Northern China Area Army. It was headquartered in Nanjing throughout the Second Sino-Japanese War.

The North China Area Army was maintained as a subordinate unit headquartered in Peking and was responsible for operations in the north China plains from the Yellow River to the Great Wall, including Inner Mongolia.

The Japanese Sixth Area Army covered central and southern China, and several independent armies reporting directly to the central command in Nanjing were used for garrison, strategic reserve and for specific operations.

By the war's end it consisted of 1,050,000 men in one armored and 25 infantry divisions. It also contained over 22 Independent brigades; 11 infantry, 1 cavalry, and 10 mixed (combined infantry, artillery, armor and support units). Towards the end of the war much of its ammunition reserve and many of its units had been transferred into the Pacific Theater leaving the China Expeditionary Army weak and undermanned.

The China Expeditionary Army surrendered on August 15, 1945 but its troops remained armed to provide security until Allied troops arrived.
