It wasn’t a sudden decision of the Japanese army to bomb Pearl Harbor, it was a long series of events which led to Pearl Harbor bombing. In fact, in the years antecedent to 1941 there was a lot of tension between the two countries. There were several events which scattered the attack on Pearl Harbor which was then used by the American government as an alibi to declare war to Japan.
Over the course of the 1930s, Japan's increasingly expansionist policies brought it into renewed conflict with its neighbors, Russia and China (1). On January 15, 1936, Japan withdrew from the Second London Naval Disarmament Conference because the United States and Great Britain refused to grant the Imperial Japanese Navy (IJN) parity with their navies.
Secondly, Japan was taking advantage of the turmoil in Europe for its own agenda of furthering its empire in the Pacific. President Roosevelt strongly condemned the Japanese assault on China and ended a long-standing commercial treaty with Japan. Japan continued their drive and seized the capital of Vietnam, a French colony. When Japan still disregarded Roosevelt’s stern warnings, all Japanese assets in the U.S were frozen and a complete trade embargo was established. This

American Intelligence broke Japanese codes but misunderstood the intent of the Japanese messages. Decoded messages made it clear that an attack would come in a matter of days after November 29, but the place of attack was not clear. Most officials were convinced Japan would move against British or Dutch possessions to the south. American Intelligence noted a fleet of Japanese ships sailing in the general direction of Hawaii but was more concerned with a large Japanese convoy moving toward the China Sea. Partly because of the vast distance between Hawaii and Japan, few officials believed an attack was possible on American territory.
In 1940, the United States was extremely against this animosity and reacted with trade embargoes and monetary approvals. FDR had talked with the Dutch and the British to see if they would agree upon embargoes on Japan. Franklin Delano Roosevelt did not want a conflict in the pacific as the United States was not prepared for war. For instance, the oil embargo that was organized between the British, the Dutch, and the United States was about 90% of Japan’s imported oil. [3] This upset Japan because without oil or fuel their military and war efforts would come to a complete stop.
The United State’s direct involvement in World War II officially began as soon as the Japanese bombed Pearl Harbor. Prior to that event, America had been providing arms and equipment to England but stopped short of any direct military confrontation with the Axis. The War in the Pacific was considered Asia’s War and the European War was considered a local conflict. US-Japanese relations had become strained in 1941, though America felt secure that her naval fleet at Pearl Harbor, Hawaii was powerful enough to discourage any aggression from Japan. On July 24, 1941, Japan occupied French Indo-China (Vietnam, Cambodia, Laos). Two days after that, President Franklin Delano Roosevelt froze all Japanese assets in the United States. American trade
To impose imperialistic goals and enhance nationalistic beliefs, the Japanese needed to significantly hinder the growth of the US economy, specifically, so that they could not enter into a Pacific war. Admiral Isoruko Yamamoto made it clear that they could not completely knock out America, because of their large economy. However, they believed that by attacking America’s main naval base, Pearl Harbour, they could prevent America’s entry into a Pacific war for 2 years. Therefore, this time would give the Japanese the opportunity to expand and occupy South East Asia without American intervention. The signing of the Tripartite Pact in September 1940, which allied Japan with Germany and Italy, provoked tension between the United States and Japan joined the Axis Powers. Negotiations in Washington were useless because of the almost diametrically opposite aims of the parties. Japan wanted America to abandon all support of the Chinese government and in return Japan would consider withdrawing from the Axis Pact. America distrusted the Japanese and wanted them to withdraw from Indochina and China. The Japanese were beginning to resent negotiations and believed that by the time America had recovered Japan would have acquired enough land and power that the US would accept a peace offer to avoid costly confrontation because by this time the navy would have established a defense perimeter of
After the world war I allied countries had signed the treaty of Versailles. Japan had felt left out because it wanted to include a part about racial equality. They felt that they weren't being treated equally. So Japan had started to take control and conquer land in southeast Asian countries. They wanted to spread their rule and race. The U.S. didn’t agree with Japan’s action and over the years tension has developed between the two countries. Japan bombed Pearl Harbor because of their nationalist mindset, America’s embargo of oil, and the fear of being attacked by the United States because of its growth.
Have you ever felt threatened by the one you once called a friend? American’s know this feeling all too well. In 1919, the major world powers met to deal with the wreckage that had occurred in World War 1, among those present were Japan and the United States. Japan was unhappy about how Great Britain and The United States punished Germany, the Japanese saw it as they were trying to stick to the status quo and to not cause a commotion within the League of Nations.
The passing of the Lend-Lease Act gave the United States permission to fund nations such as Britain and France, with guns, other arms. It allowed the United States get involved, while claiming neutrality.
An event that shook the nation, will not bring it to its knees. Japan bombed Pearl Harbor, Hawaii and afterward, the U.S. entered the war. What reason did the Japanese have to bomb Pearl Harbor? Japan attacked Pearl Harbor because they saw the U.S. as a threat because they cut off their reasons, threatened them by moving military forces, and they stand in the way of Japan’s new order.
A third reason for the attack was a new world order. New world order is an idea where Japan will rule the entire world. In document “C” it states, “December 1941 Japan attacks Pearl Harbor.” Japan did this because the US moved the Navy & took off resources. Also in document “B” it mentions that Japan is more interested in seizing all oil fields and the only way to do what they had to do was by invading the “Netherland East Indies” and they did “after the Pearl Harbor Bombing.” A new world order caused the Japanese to attack because the US expanded the navy and stopped oil embargoes.
Japan and the United States had different kinds of relations that could have lead Japan to bomb Pearl Harbor.The United States military and Japan’s relationship seemed to get worse after Japan sank the USS Panay even though Japan apologized for sinking the ship. Japan became aware in the 19th and 20th century that there was threats from different nations influence became very loyal. During 1939 - 1945 the United States, for the second time, applied domestic penalties to Japan and sends to Europe military supplies because Germany, Italy, and Japan made the Anti Comintern Pact. Japan wanted to take control over some land in northeastern China, this lead to domestic penalties that were charged against Japan from the United States and Europe. Even though the United States saw Japan as a minor threat because Japan had a little military compared to the United States navy. Japan decided

Overall, Japan had many reasons that led to the attack and bombing of Pearl Harbor. Although the attack on Pearl Harbor may have been an overdue response to the decisions made after World War I, Japan also wanted to put their plan into place for a new world order, the United States oil embargo against them caused issues, and the expansion of the American naval fleet frightened them. Japan attacked Pearl Harbor because they wanted to gain power and leadership in the
What did all of this have to do with the U.S.? Well, because the U.S. had ties with East Asia, politically and economically, the decisions Japan were making were also affecting the U.S. So, America took it upon itself to increase military and financial aid to China. The reason this decision was made was to cut off oil shipments and raw materials to Japan. This is what really angered the Japanese.
(Higgs). Japan was angered by the United States putting these sanctions on them, as they thought of the attack on China as internal affairs. As many countries in Europe also placed economic sanctions on Japan , that led to Japan withdrawing from the League of Nations in 1933. After withdrawing from the League of Nations, Japan launched a huge attack on eastern China and eventually Japan took over the capital of China, Nanking. ("Japan Launches A Surprise Attack on Pearl Harbor: December 7, 1941"). The view on Japan to worsened when Japan sunk an American Gunboat, Panay, while the boat was on patrol on the Yangtze River. The Japanese later apologized for the sinking of the Panay but the chances for an American-Japanese battle increase. ("Japan Launches A Surprise Attack on Pearl Harbor: December 7, 1941").
The notice for an attack would come via an intercepted transmission on December 6 to the Japanese Ambassador detailing a secretive 14 part message due to be transmitted and when advised, given to the American authorities. 13 parts were received and deciphered before midnight on December 6. Those 13 parts contained a history from Japan's perspective on what had happened in the war thus far and how they felt about it. Part 14, the most important part, was received by the decoders at 4am on December 7. By 10am they had deciphered and sent it to President Roosevelt. At 10.30am an addition to the message was received. It detailed that the message was to be handed over by the Ambassador at 1pm that afternoon. This also happened to be the time for the first attack however no location was given. Henry L Stimson the Former Secretary of War as recorded in What Happened at Pearl Harbour states the following regarding the MAGIC code:
In July 1940, the U.S. placed an embargo on Japan, hoping they would restrain Japan 's military aggression in China. Japan, a proud nation, would not hear of being dictated to by the United States and began to prepare for the attack on Pearl Harbor in early 1941. Meanwhile, there was some warning of the attack on America, but it went without being duly acknowledged. The day before the attack occurred, a code-breaker intercepted a message from the Japanese concerning the movement of ships at Pearl Harbor. The operator relayed the message to the superior officers who said they would get back to the radioman on Monday, December 8, 1941 (Socolow 43). Also, on the morning of the attack, a radar operator saw a large group of airplanes on the radar screen, and when he reported this, the senior officer said it was probably just some US Bombers and not to worry about them (HistoryNet.Com). The Japanese planes flew under the radar by flying through a pass in the mountains called Kolekole Pass. This maneuver added to the surprise of the attack. The frantic attack began on Sunday at 7:55 in the morning. A little before ten the entire attack was over (Pearl Harbor, Attack On). The men of Pearl Harbor fought with valor.
