Anti-Japanese sentiment in the United States has existed since the late 19th century, especially during the Yellow Peril, which had also extended to other Asian immigrants.

Anti-Japanese sentiment against American citizens of Japanese descent in the United States would peak during World War II, when the Empire of Japan became involved in the Pacific War theater. After the war, the rise of Japan as a major economic power in the 1970s was seen as a widespread economic threat to the United States and also led to a renewal of anti-Japanese sentiment, known as Japan bashing.

Origins

In the United States, anti-Japanese sentiment had its beginnings well before World War II. Racial prejudice against Asian immigrants began building soon after Chinese workers started arriving in the country in the mid-19th century, and set the tone for the resistance Japanese would face in the decades to come. Although Chinese were heavily recruited in the mining and railroad industries initially, whites in Western states and territories came to view the immigrants as a source of economic competition and a threat to racial purity as their population increased. A network of anti-Chinese groups (many of which would reemerge in the anti-Japanese movement) worked to pass laws that limited Asian immigrants' access to legal and economic equality with whites. Most important of these discriminatory laws was the exclusion of Asians from citizenship rights. The Naturalization Act of 1870 revised the previous law, under which only white immigrants could become U.S. citizens, to extend eligibility to people of African descent. By designating Asians as permanent aliens, the law prohibited them from voting and serving on juries, which, combined with laws that prevented people of color from testifying against whites in court, made it virtually impossible for Asian Americans to participate in the country's legal and political systems. Also significant were alien land laws, which relied on coded language barring "aliens ineligible for citizenship" from owning land or real estate, and in some cases from even entering into a temporary lease, to discourage Asian immigrants from establishing homes and businesses in over a dozen states.Lyon, Cherstin M. "Alien land laws," Densho Encyclopedia. Retrieved 15 July 2014. These laws were greatly detrimental to the newly arrived immigrants, since many of them were farmers and had little choice but to become migrant workers.

After the Chinese Exclusion Act of 1882 stopped immigration from China, American labor recruiters began targeting Japanese workers, triggering a rapid increase in the country's Japanese population, which in turn triggered the movement to decrease their number and restrict their economic and political power.Anderson, Emily. "Anti-Japanese exclusion movement," Densho Encyclopedia. Retrieved 15 July 2014. Some cite the formation of the Asiatic Exclusion League as the start of the anti-Japanese movement in California, where, along with the Japanese American population, the exclusion movement was centered.. Their efforts focused on ending Japanese immigration and, as with the previous anti-Chinese movement, nativist groups like the Asiatic Exclusion League lobbied to limit and finally, with the Immigration Act of 1924, ban Japanese and other East Asians from entering the U.S. However, in the process they created an atmosphere of systematic hostility and discrimination that would later contribute to the push to incarcerate 120,000 Japanese Americans during World War II.

Early 20th century

Anti-Japanese racism and fear of the Yellow Peril had become increasingly xenophobic in California after the Japanese victory over the Russian Empire in the Russo-Japanese War. On October 11, 1906, the San Francisco, California Board of Education passed a regulation whereby children of Japanese descent would be required to attend racially segregated and separate schools. At the time, Japanese immigrants made up approximately 1% of the population of California; many of them had come under the treaty in 1894 which had assured free immigration from Japan.

In 1907, Californian nativists supporting exclusion of Japanese immigrants and maintenance of segregated schools for Caucasian and Japanese students rioted in San Francisco.

Alien land laws The California Alien Land Law of 1913 was specifically created to prevent land ownership among Japanese citizens who were residing in the state of California. In State of California v. Jukichi Harada (1918), Judge Hugh H. Craig sided with the defendant and ruled that American children – who happened to be born to Japanese parents – had the right to own land. California proceeded to strengthen its Alien land law in 1920 and 1923.Kurashige, Scott. (2008). The Shifting Grounds of Race: Black and Japanese Americans in the Making of Multiethnic Los Angeles. Princeton: Princeton University Press.Bunje, Emil T. H. (1957). The Story of Japanese Farming in California. Saratoga, California: Robert D. Reed.

Other states passes similar laws including Washington in 1921 and Oregon in 1923.

In State of California v. Oyama (1948),State of California v. Oyama, 332 U.S. 633 (1948). the U.S. Supreme Court ruled that California's Alien Land Law was anti-Japanese in concept, and deemed unfit to stand in America's law books. Justices Murphy and Rutledge wrote:

It took four years for California's Supreme Court to concede that the law was unconstitutional, in State of California v. Fujii (1952). Finally, in 1956, California voters repealed the law.

Anti-Japanese immigration agreements and legislation In 1907, the Gentlemen's Agreement was an informal deal between the governments of Japan and the U.S. It ended the immigration of Japanese laborers, though it did allow the immigration of spouses and children of Japanese immigrants already in the United States.Esthus, Raymond A. (1967) Theodore Roosevelt and Japan. University of Washington Press. pp. 146–166, 210–228.

The Immigration Act of 1924 banned the immigration of all but a few token Japanese. Passage of the Immigration Act contributed to the growth of anti-Americanism and ending of a growing democratic movement in Japan during this time period, opening the door to Japanese militarist government control.

Japanese military activity prior to American entry in World War II The Japanese invasion of China in 1931 and the annexation of Manchuria was roundly criticized in the US. In addition, efforts by citizens who were outraged by Japanese atrocities, such as the Nanjing Massacre, led to calls for American economic intervention to encourage Japan to leave China; these calls played a role in shaping American foreign policy. As more and more unfavorable reports of Japanese actions came to the attention of the American government, embargoes on oil and other supplies were placed on Japan, out of concern for the safety of the Chinese populace and concern for the safety of American interests in the Pacific.

Chinese Americans were again distressed when an estimated 150,000 Taishanese locals died from starvation in Taishan County by the Japanese blockade, as Taishan County was the homeland of most Chinese Americans at that time.

When the Second Sino-Japanese War broke out in 1937, Western public opinion was decidedly pro-China, with eyewitness reports by Western journalists on atrocities committed against Chinese civilians further strengthening anti-Japanese sentiments. African American sentiments at the time could be quite different than the mainstream, with organizations like the Pacific Movement of the Eastern World (PMEW) which promised equality and land distribution under Japanese rule. The PMEW had thousands of members hopefully preparing for liberation from white supremacy with the arrival of the Japanese Imperial Army.

World War II

The most profound cause of anti-Japanese sentiment outside of Asia had its beginning in the attack on Pearl Harbor, as it propelled the United States into World War II. The Americans were unified by the attack to fight against the Empire of Japan and its allies, the German Reich and the Kingdom of Italy.

The bombing of Pearl Harbor by Japan on the neutral United States without warning and the deaths of almost 2,500 people during ongoing U.S./Japanese peace negotiations was presented to the American populace as an act of treachery, barbarism, and cowardice. Following the attack, many non-governmental "Jap hunting licenses" were circulated around the country. Life magazine published an article on how to distinguish a Japanese person from a Chinese person by the shape of the nose and the stature of the body. Japanese conduct during the war did little to quell anti-Japanese sentiment. Fanning the flames of outrage were the treatment of American and other prisoners of war. Military-related outrages included the murder of POWs, the use of POWs as slave labor for Japanese industries, the Bataan Death March, the kamikaze attacks on Allied ships, and atrocities committed on Wake Island and elsewhere. The Guadalacanal Diary, which was published in 1943, wrote about the accounts of American soldiers, collecting Japanese 'gold teeth' or body parts such as hands or ears, to keep as trophies.Tregaskis, Richard (1943) Guadalacanal diary. Random House. pp. 15–16 The diary became extremely popular within the United States during the Second World war.

U.S. historian James J. Weingartner attributes the very low number of Japanese in U.S. POW compounds to two key factors: a Japanese reluctance to surrender and a widespread American "conviction that the Japanese were 'animals' or 'subhuman' and unworthy of the normal treatment accorded to POWs." The latter reasoning is supported by Niall Ferguson, who says that "Allied troops often saw the Japanese in the same way that Germans regarded Russians [sic] — as Untermenschen." Weingartner believes this explains the fact that a mere 604 Japanese captives were alive in Allied POW camps by October 1944.

Ulrich Straus, a U.S. Japanologist, believed that front line troops intensely hated Japanese military personnel and were "not easily persuaded" to take or protect prisoners. They believed that Allied personnel who surrendered got "no mercy" from the Japanese.Straus, Ulrich (2003) The Anguish Of Surrender: Japanese POWs of World War II (excerpts) Seattle: University of Washington Press. p. 116. Allied soldiers believed that Japanese soldiers were inclined to feign surrender, in order to make surprise attacks. Therefore, according to Straus, "[s]enior officers opposed the taking of prisoners[,] on the grounds that it needlessly exposed American troops to risks..."

The attack on Pearl Harbor on December 7, 1941, plunged the United States into war and planted the notion that the Japanese were treacherous and barbaric in the minds of Americans. The hysteria which enveloped the West Coast during the early months of the war, combined with long standing anti-Asian prejudices, set the stage for what was to come.A More Perfect Union. 1990–2001.
