Ethnic groups of Japan

Among the several native ethnic groups of Japan, the predominant group are the Yamato Japanese, who trace their origins back to the Yayoi period and have held political dominance since the Asuka period. Other historical ethnic groups have included the Ainu, the Ryukyuan people, the Emishi, and the Hayato; some of whom were dispersed or absorbed by other groups. Ethnic groups that inhabited the Japanese islands during prehistory include the Jomon people and lesser-known Paleolithic groups. In more recent history, a number of immigrants from other countries have made their home in Japan. According to census statistics in 2018, 97.8% of the population of Japan are Japanese citizens, with the remainder being foreign nationals residing in Japan. The number of foreign workers has been increasing dramatically in recent years, due to the aging population and the lack of labor force. A news article in 2018 states that approximately 1 out of 10 young people residing in Tokyo are foreign nationals.

About 2.3% of Japan's total legal resident population are foreign citizens. Of these, according to 2020 data from the Japanese government, the principal groups are as follows.

The above statistics do not include the approximately 30,000 U.S. military stationed in Japan, nor do they account for illegal immigrants. The statistics also do not take into account minority groups who are Japanese citizens such as the Ainu (an aboriginal people primarily living in Hokkaido), the Ryukyuans (from the Ryukyu Islands south of mainland Japan), naturalized citizens from backgrounds including but not limited to Korean and Chinese, and citizen descendants of immigrants. The total legal resident population of 2012 is estimated at 127.6 million.

After the demise of the multi-ethnic Empire of Japan in 1945, successive governments had forged a single Japanese identity by advocating monoculturalism and denying the existence of more than one ethnic group in Japan. It was not until 2019 when the Japanese parliament passed an act to recognize the Ainu people to be indigenous. However, the notion of ethnic homogeneity was so ingrained in Japan, to which the former Prime Minister Taro Aso (1940–), in 2020, notably claimed in an election campaign speech that "No other country but this one has lasted for as long as 2,000 years with one language, one ethnic group and one dynasty".

Pioneering remarks about ethnic rights was first made by Prime Minister Fukuda Yasuo on 20 May 2008, who stated at the parliament, "We acknowledge the Ainu to be an ethnic minority as it has maintained a unique cultural identity and having a unique language and religion."

Historical minorities: (arrived in Japan before or during 1700)

Modern minorities: (arrived in Japan after 1700)

The Ainu people (also Aynu) are an indigenous people native to Hokkaido and northeastern Honshu, as well as the nearby Russian Sakhalin and Kuril Islands (both formerly part of the Japanese Empire), and Kamchatka Peninsula. They possess a language distinct from modern Japanese. They traditionally practiced tattooing and followed religious beliefs that are considered animism.^{[citation needed]}
