When the Pacific War broke out on December 7, 1941, the Kwantung Army had 730,000 troops and China sent 620,000 troops, totaling 1.35 million troops.

When the Japanese surrendered. The "Chinese Dispatch Army" was 1.05 million, and the Kwantung Army surrendered 680,000 to the Soviet Army, totaling 1.73 million people.

The Japanese Army had 17 divisions and regiments before the "77 Incident", and 156 divisions (excluding tank divisions and anti-aircraft divisions) were formed during the war (including reorganization and reorganization, such as the first division), with a total of 173 divisions and regiments.

Among them, the 1st General Army and the 2nd General Army stationed on the mainland have 53 divisions and regiments, 62 divisions and regiments (including the 56th Division) before and after the battlefield in China's Guannai, and 58 divisions before and after the Kwantung Army. In total, 120 divisions entered the Chinese battlefield.

Based on the average of 10,000 people in one Japanese full-strength division at that time, the number of troops that Japan invested in the Chinese battlefield before and after was 4.2 million.

At the time of the surrender, the total number of Japanese troops reached 7.2 million. Among them, 1.05 million were "Chinese troops", accounting for 15%; The Kwantung Army surrendered 680,000 to the Soviet army, accounting for 9%. The total number of Southern Army and "Domestic Army" that surrendered to the Allied forces led by the United States in the Pacific Theater was about 5.5 million, accounting for 76%.

At the end of the war, 1.05 million of the "Chinese Dispatch Army" surrendered, and about 550,000 Japanese troops were wiped out during the war. Nearly 1 million wounded were also repatriated, so the total number of troops that Japan committed to China during World War II was more than 2.6 million.

The Japanese army in northern Vietnam belonged to the Southern Army and surrendered to China in accordance with the principle of proximity; The 160,000 Japanese troops in Taiwan belonged to the Japanese army"Domestic Army"The 10th Front was mainly to resist the landing of American troops.

In 1937, Japan's total population was 70.63 million, of which 16.93 million were men of military age, and the number of men of military age who could be conscripted accounted for about 10 million percent, and the total strength of the Japanese army at that time was 10,000, which expanded to more than 7.2 million in 1942. In 1941, Japan launched the Pacific War, the United States and other 26 countries declared war on Japan, Japan put the main forces into the Pacific theater, and when it surrendered in 1945, Japan had only more than 1 million troops in China. By the end of 1941, Japan's total strength had reached 2.4 million, of which about 300,000 were navy, part of which was put into the Pacific theater and part of it was tied to the Chinese theater, while its 2.1 million army troops were exhausted on the Chinese battlefield in addition to 400,000 remaining on the mainland, and only 400,000 army troops could be put into the Pacific theater.

It was during the most intense and dangerous days of the Allied battles in the Pacific Theater that more than 2 3 of the total strength of the Japanese Army was "nailed" to the Chinese battlefield and could not move, causing its "southward advance" plan to be delayed again and again, thus enabling the Allied forces in the Pacific Theater to pass through the most dangerous period.

Japan invested 4.1 million people in the war of aggression against China (at its peak), and China invested 5.6 million people (at its peak).

Japan's war of aggression against China generally refers to the War of Resistance Against Japan.

The War of Resistance Against Japanese Aggression refers to a national all-out war in which China resisted Japanese aggression in World War II in the mid-20th century. From the July 7 Incident in 1937 to the end of Japan's surrender in 1945, it lasted eight years, known as the Eight-Year War of Resistance Against Japanese Aggression, or simply the War of Resistance Against Japanese Aggression.

In 1931, after the invading Japanese army launched the 918 Incident, it completely occupied Northeast China and established the puppet state of Manchukuo. On July 7, 1937, the Japanese army provoked the Lugou Bridge Incident near Beiping, and the Sino-Japanese War broke out.

In the early days of the war, China invested a large number of troops to contain the Japanese offensive; After Japan launched the Pacific War on December 7, 1941, Roosevelt of the United States officially declared war on Japan, and the Chinese battlefield became one of the main battlefields of World War II (abbreviation of World War II).

On August 15, 1945, Japan surrendered unconditionally to the Allies. The War of Resistance Against Japanese Aggression caused huge losses to China in terms of personnel and property, but in the course of the war, the people's sense of the state was strengthened, and the victory of the war greatly improved China's position on the world stage.
