Antisemitism in Japan has developed over the years despite the presence of a relatively small and obscure Jewish population. Japan had no traditional antisemitism until nationalist ideology and propaganda began to spread on the eve of World War II. Before and during the war, Nazi Germany, an ally to the Japanese, encouraged Japan to adopt antisemitic policies. In the post-war period, extremist groups and ideologues have promoted conspiracy theories.
In 1918, the Imperial Japanese Army sent troops to Siberia to cooperate with the White movement. White Army soldiers had been issued copies of The Protocols of the Elders of Zion, and Japanese soldiers first learned about antisemitism. The Protocols continue to be used as evidence of Jewish conspiracies even though they are widely acknowledged to be a forgery.
According to Dr. David Kranzler:
In 1925 Captain Norihiro Yasue published the first translation of the Protocols in Japanese. A Russian-language specialist, he was assigned to the staff of General Gregorii Semenov, a vehement anti-Semite who distributed copies of the Protocols to all of his troops. Along with a few dozen other Japanese soldiers, Yasue read and accepted the premises of the Protocols, and contributed for a time to various antisemitic publications, including Kokusai Himitsu Ryoku no Kenkyu (å½éÂÂç§Âå¯ÂÃ¥ÂÂã®ç Â究, Studies in the International Conspiracy), under the pen-name Hà  Kà Âshi. He later changed his views when in 1940 Japan signed the Tripartite Pact which formally sealed Japan's alliance with Nazi Germany. His newly pro-Semitic stance led to his dismissal from the Japanese Army.
During the 1930s Minetaro Yamanaka (å±±ä¸Â峯太éÂÂ) wrote stories about the Yudayaka, the "Jewish Peril." A major journalist at the Tokyo Asahi Shimbun, Yamanaka was a prolific author of children's fiction who serialized the novel Daità  no Tetsujin (Superman of the Great Orient) from August 1933 until the end of 1934 in the periodical Shà Ânen Kurabu (Boys' Club), read mainly by Japanese boys between the ages of 8 and 12. The hero of this story is the detective Hongà  Yoshiaki who battles the villain Sekima, head of the shadowy Zion Alliance, a Jewish secret organization seeking to undermine the Japanese Empire. A typical quote from Superman of the Great Orient:
Yamanaka stopped writing with the surrender of Japan in August 1945, but Kodansha Ltd. continued reprinting this series until the 1970s.
In 1936 Lieutenant General Nobutaka Shià Âden re-translated the Protocols into Japanese. Shià Âden had become a fervent anti-Semite and a believer in Jewish conspiracy theory while he was studying in France. When he returned to Japan he became the leading voice of antisemitic propaganda.
Brian Victoria states that Tanaka Chigaku promoted antisemitism in Japan starting in 1937 with the publication of Shishi-à  Zenshà « Daisan-shà « (Complete Works of the Lion King), in which he said:
According to Victoria, "Tanaka argued that Jews were fomenting social unrest in order to rule the world. He ... [points out] that Jews advocated liberalism, especially within academic circles, as part of their plan to destroy the people's moral sense ... Helped by men like Tanaka, antisemitism spread rapidly throughout Japanese society despite the near-total absence of Jews."
Also during the 1930s, Japan circulated antisemitic publications and sentiment within China. Under Japanese occupation in the 1930s, the Jews of Harbin were the victims of antisemitism by the White Russian fascist elements. The Japanese occupiers tolerated this antisemitic treatment. As a result, many Jews of Harbin fled to Shanghai.
On 8 February 1943, the Japanese occupiers created what they described as the designated area (the Shanghai ghetto) in Hongkew where they re-located and segregated the Jewish refugees whom Nazi Germany had stripped of citizenship. Jews in the Japanese-run ghetto could not leave without a pass and experienced extreme poverty. The Shanghai ghetto lasted until the Japanese surrendered in 1945.
During the Holocaust, since Shanghai was one of the few places in the world that did not need require a visa or travel documents. In 1941, Japanese forces began systematically taking control of the areas of Shanghai which they had not previously occupied. In November of that year, Nazi Germany stripped Jews abroad of their citizenship, resulting in Jews abroad becoming stateless refugees. SS-Colonel Josef Meisinger tried to influence the Japanese to exterminate approximately 18,000âÂÂ20,000 stateless Jews who had escaped from Austria and Germany and who were living in Japanese-occupied Shanghai. His proposals included the creation of a concentration camp on Chongming Island in the delta of the Yangtze, or starvation on freighters off the coast of China. The Japanese built a ghetto in the neighborhood of Hongkew. The ghetto was strictly isolated by Japanese soldiers under the command of the Japanese official Kano Ghoya, and Jews could only leave it with special permission. Japanese authorities censored Jewish cultural activities. The Jews forced to live in the ghetto experienced extreme poverty. Some 2,000 of them died in the Shanghai Ghetto during the wartime period.
However, Japan refused to adopt an official policy against the Jews. On 31 December 1940, Japanese foreign minister YÃ Âsuke Matsuoka told a group of Jewish businessmen: "Nowhere have I promised that we would carry out Hitler's anti-Semitic policies in Japan. This is not simply my personal opinion, it is the opinion of Japan." Nonetheless, until 1945 the Holocaust was systematically concealed by the leadership in Tokyo.
Brian Victoria also states that Haku'un Yasutani "was one of the few Zen masters to integrate virulent antisemitism into his pro-war stance." He quotes Yasutani's 1943 Dà Âgen Zenji to Shà «shà Âgi:
<blockquote>We must be aware of the existence of the demonic teachings of the Jews who assert things like [the existence of] equality in the phenomenal world, thereby distorting public order in our nation's society and destroying [governmental] control. Not only this, these demonic conspirators hold the deep-seated delusion and blind belief that ... they alone have been chosen by God and are [therefore] an exceptionally superior people. The result of all this is a treacherous design to usurp [control of] and dominate the entire world, thus provoking the great upheavals of today.</blockquote>
Although Yasutani was well known to have been a friend and mentor of the Nazi propagandist Karlfried Graf Dürckheim, Victoria feels that Japanese antisemitism evolved independently from the "heart of the 'home-grown' reactionary social role that institutional Buddhism played in Japanese society following the Meiji Period."
At the end of the 20th century, many books about Japanese-Jewish common ancestry theory were sold. Numerous theories and explanations for the alleged Jewish control of the world were circulated. These books, called tondemo-bon (outrageous or preposterous books), contained elements of the occult and tabloid-style speculation.
In 1979, a book named æÂ¥æ¬人ã«è¬ÂãÂÂãÂÂã ãÂÂãÂÂã¦ãÂÂã¤人ã®æºæ Nihonjin ni ayamaritai - Aru yudayajin no zange (I'd like to apologize to the Japanese: A Jewish elder's confession) was published. The author of this book, Mordecai Mose (ã¢ã«ãÂÂã«ã¤ãÂȋ¢ã¼ã¼), called himself a rabbi, but actually, it was a pseudonym of the self-styled translator of this book, Masao Kubota (ä¹ ä¿Âç°æ¿ç·). Kubota also spread the rumor that "Enola Gay" means "Kill the Emperor" in Yiddish. This rumor is groundless, but anti-Semites in Japan still give credence to it.
In 1984, a book named ä¸ÂçÂÂãÂÂÃ¥ÂÂãÂÂãÂÂã¦ãÂÂã¤ãÂȋÂÂã¯ã¼ã®ç§Â寠Sekai wo ugokasu yudaya pawah no himitsu (Secrets of the Jewish Power that Controls the World) was published. This book is based on Jewish conspiracy theory. The author, Eizaburo Saito (æÂÂè¤æ Âä¸ÂéÂÂ), was a leading member of the Liberal Democratic Party.
In 1986, a book named ã¦ãÂÂã¤ãÂÂ解ãÂÂã¨ä¸ÂçÂÂãÂÂè¦ÂãÂÂã¦ãÂÂã Yudaya ga wakaruto sekai ga miete kuru (To Watch Jews Is to See the World Clearly) became one of Japan's best sellers. This book is also based on the Protocols and the author, Masami Uno (å®ÂéÂÂæ£ç¾Â), writes that the Ashkenazim are actually descendants of Khazarian, hence they are "fake Jews," and that Sephardim are true pedigreed Jews. According to him, some of the Japanese are the descendants of the Ten Lost Tribes of Israel and that the Japanese Sephardim will defeat the Ashkenazim.
The same year a book named ãÂÂãÂÂãÂÂãÂÂã®10å¹´é ã¦ãÂÂã¤ãÂȋÂÂãÂÂãÂÂã³ã¼ã«趠è£ÂèªÂã¿è¡ÂâÂÂãÂÂãªãÂÂã«起ãÂÂãÂÂã·ã§ãÂÂãÂÂã³ã°ãªç¾宠Yudaya purotokoru cho-urayomi-jutsu (The Expert Way to Read Jewish Protocols) also became one of Japan's bestsellers. The author, Kinji Yajima (ç¢島éÂÂ次, 1919âÂÂ1994), an economist and a professor at Aoyama Gakuin University, stated that although the Protocols is probably a forgery,
In 1987, a magazine named æ´å²èªÂæ¬ Rekishi dokuhon (The History Magazine) featured articles titled ä¸ÂçÂÂãÂÂè¬Âã®ã¦ãÂÂ㤠Sekai, nazo no yudaya (The world of the Mysterious Jews), which insisted that the Watergate scandal and the Lockheed bribery scandals were Jewish conspiracies. It also reported that former prime minister Kakuei Tanaka said "Yudaya Nelson Rockefeller ni yarareta, yudaya ni ki wo tsukero," [I've been gotten by Jews, Nelson Rockefeller, be wary of Jews] when he was released on bail in 1976.
Between 1992 and 1995 Aum Shinrikyo, a controversial Buddhist religious group, also distributed conspiracy theories to attract Japanese readers as part of their recruitment efforts. Its founder, Shoko Asahara, was influenced by Goto Ben's 1973 book, ãÂÂã¹ãÂÂã©ãÂÂã ã¹ã®大äºÂ訠Nostradamusu no Daiyogen (Prophecies of Nostradamus), a loose translation of the Prophecies which became a bestseller in Japan. Hideo Murai, one of the leaders of Aum Shinrikyo, uttered the words "" when he was stabbed to death.
In February 1995 a magazine named Marco Polo (ãÂÂã«ã³ãÂÂã¼ãÂÂ), a 250,000-circulation monthly aimed at Japanese males, ran a Holocaust denial article by physician Masanori Nishioka (西岡æÂÂç´Â) which stated:
The Los Angeles-based Simon Wiesenthal Center instigated a boycott of Bungei Shunju advertisers, including Volkswagen, Mitsubishi, and Cartier. Within days, Bungei Shunju shut down Marco Polo and its editor, Kazuyoshi Hanada, quit, as did the president of Bungei Shunju, Kengo Tanaka.
In October 1999 a Japanese publication, The Weekly Post, published a story on the proposed acquisition of the Long-Term Credit Bank of Japan by Ripplewood Holdings, which the article described as being "Jewish":
This soon generated strong complaints by Jewish groups, particularly outside Japan. The Weekly Post quickly retracted the article and carried an apology on its home page. The publication explained its error by noting that "the problem stemmed from the stereotyped image of the Jewish people that many Japanese people have."
Since the turn of the century, Ryu Ota, an ex-Trotskyist, is one of the leading propagandists for Jewish conspiracy theory. He has translated the books of Eustace Mullins into Japanese.
On March 8, 2009, Soichiro Tahara (ç°åÂÂç·Âä¸ÂæÂÂ), political journalist and host of TV Asahi's Sunday Project program, told Makiko Tanaka that her father, former Prime Minister Kakuei Tanaka, was "done in by America, by the Jews and Ozawa, (leader of the Democratic Party of Japan) too, was done in [by America and/or the Jews]" during a live broadcast. The Simon Wiesenthal Center strongly criticized Tahara for antisemitic and anti-American accusations.
In 2014, 31 municipal libraries in Japan reported having 265 copies of The Diary of a Young Girl by Anne Frank and other books vandalized, usually with several pages torn or ripped out. Chief Cabinet Secretary Yoshihide Suga said that police were investigating. Japanese politician Nariaki Nakayama said that the act could not have been committed by a Japanese, saying that it was against Japanese sensibilities. A 36-year-old man was arrested in connection with the vandalism on March 14, however in June prosecutors announced that they would not press charges after a psychiatric evaluation revealed that the man was mentally incompetent.
A 2014 ADL telephone survey asserted that of 500 people, 23% +/- 4.4% of the adult population in Japan harbor antisemitic attitudes. Furthermore, the study reveals that 46% of the population agree with the statement "Jews think they are better than other people", and that almost half of the respondents (49%) think that "Jews are more loyal to Israel than to Japan." However, this survey has been critiqued by journalist Jesse Singal as being unreasonably simplistic in its classification of "harboring antisemitic attitudes".
