Japan in World War II
This timeline shows the participation of Japan during World War II. -
Japan invades Manchuria
the Japanese Kwangtung Army attacked Chinese troops in Manchuria in an event commonly known as the Manchurian Incident. Essentially, this was an attempt by the Japanese Empire to gain control over the whole province, in order to eventually encompass all of East Asia. This proved to be one of the causes of World War II. -
German-Japanese Alliance
Anti-Comintern Pact, agreement concluded first between Germany and Japan (Nov. 25, 1936) and then between Italy, Germany, and Japan (Nov. 6, 1937), ostensibly directed against the Communist International (Comintern) but, by implication, specifically against the Soviet Union. -
Japan invades China for the second time.
The Second Sino-Japanese War was a military conflict fought primarily between the Republic of China and the Empire of Japan from July 7, 1937, to September 2, 1945. It began with the Marco Polo Bridge Incident in 1937 in which a dispute between Japanese and Chinese troops escalated into a battle. -
The Tripartite Pact is signed by Germany, Italy, and Japan
On this day in 1940, the Axis powers are formed as Germany, Italy, and Japan become allies with the signing of the Tripartite Pact in Berlin. The Pact provided for mutual assistance should any of the signatories suffer attack by any nation not already involved in the war. This formalizing of the alliance was aimed directly at “neutral” America–designed to force the United States to think twice before venturing in on the side of the Allies. -
Japan bombs Pearl Harbor
Japanese planes bombarded the U.S. naval base at Pearl Harbor near Honolulu, Hawaii, destroying or crippling 18 ships and killing almost 2,500 men. -
The U.S. declares war on Japan
On this day, as America’s Pacific fleet lay in ruins at Pearl Harbor, President Franklin Roosevelt requests, and receives, a declaration of war against Japan. -
Midway Battle
Six months after the attack on Pearl Harbor, the United States defeated Japan in one of the most decisive naval battles of World War II. Thanks in part to major advances in code breaking, the United States was able to preempt and counter Japan’s planned ambush of its few remaining aircraft carriers, inflicting permanent damage on the Japanese Navy. An important turning point in the Pacific campaign, the victory allowed the United States and its allies to move into an offensive position. -
Okinawa Battle
The Battle of Okinawa was the last major battle of World War II, and one of the bloodiest. On April 1, 1945—Easter Sunday—the Navy’s Fifth Fleet and more than 180,000 U.S. Army and U.S. Marine Corps troops descended on the Pacific island of Okinawa for a final push towards Japan. The invasion was part of Operation Iceberg, a complex plan to invade and occupy the Ryukyu Islands, including Okinawa. -
Hiroshima
U.S. planes dropped two atomic bombs, one on Hiroshima, another on Nagasaki, leading to the unconditional surrender of Japan and the end of World War II. -
Soviet Union Invades Manchuria
On this day in 1945, the Soviet Union officially declares war on Japan, pouring more than 1 million Soviet soldiers into Japanese-occupied Manchuria, northeastern China, to take on the 700,000-strong Japanese army. -
Nagasaki
Three days after Hiroshima´s bomb, a second B-29 dropped another A-bomb on Nagasaki, killing an estimated 40,000 people. Japan’s Emperor Hirohito announced his country’s unconditional surrender in World War II in a radio address on August 15, citing the devastating power of “a new and most cruel bomb.” -
Japan Surrenders
The surrender of Imperial Japan was announced by Hirohito on August 15 and formally signed on September 2, 1945, bringing the hostilities of World War II to a close. By the end of July 1945, the Imperial Japanese Navy (IJN) was incapable of conducting major operations and an Allied invasion of Japan was imminent.
