I assume you are referring to WWII here... it is not so much that the Japanese viewed the Americans as an enemy, so much as it was they viewed the US as a threat to their plans to expand their sphere of influence in the Pacific Ocean. Japan is a very small country in terms of land and as such, is one of the largest importers of goods in the world. Japan wanted to expand to the islands in the Pacific to eliminate some of their reliance on imports. At this time, the United States Pacific Fleet was massive, and if it remained in play, would hinder the Japanese in their goal of dominating the Pacific Ocean.
Because the US leaders feared that the Japanese Americans might help Japan in World War ll.
The American leaders banned the sale of oil to Japan to slow down a japanese war machine and this was a serious threat to future plans for the Japanese

Germany and Japan
The two main leaders were Isoroku Yamamoto for the Japanese and Chester Nimitz for the Americans.
In short to make sure that our enemys dont get them by pointing ours at them.
Japanese leaders viewed the U.S. as an enemy due to rising tensions stemming from American opposition to Japanese expansion in Asia, particularly in China and the Pacific. The U.S. imposed economic sanctions and trade restrictions, including an embargo on oil, which threatened Japan's resource supply and military ambitions. Additionally, cultural differences and the perception of the U.S. as a threat to Japanese sovereignty fueled nationalist sentiments, leading to the belief that conflict was inevitable. These factors culminated in Japan's decision to engage in military action against the U.S. during World War II.
Japanese defeat was inevitable (as likely seen by most Japanese leaders) by early 1943. The war continued simply because the Japanese would not surrender, and the US would not stop until Japan surrendered.
In short to make sure that our enemys dont get them by pointing ours at them.
The Japanese military leaders did. And Don't you forget it. Not only did they start the war, but they attacked the US without warning.
