Yamato people

The Yamato people, often simply called the Japanese, are an East Asian ethnic group making up more than 98% of Japan's population. According to genetic and anthropometric research, they mainly descend from the Yayoi people, who began migrating from the continent—likely the Korean Peninsula—around the 1st millennium BC, while also carrying some ancestry from the earlier Jōmon inhabitants of the archipelago. The term can also refer to the original settlers of Yamato Province, now Nara Prefecture. For generations, Japanese archaeologists, historians, and linguists have debated whether the word is linked to an earlier name.

Around the 6th century, the Yamato clan established Japan’s first and only dynasty, becoming the ruling faction in the region and incorporating both native islanders and mainland migrants. The clan’s leaders elevated their own ancestor-worship belief system into a national religion: Shinto. The term "Yamato" came into broader use in the late 19th century to distinguish mainland Japanese from minority groups within the Empire of Japan, such as the Ainu, Ryukyuans, Nivkh, and peoples incorporated from the early 20th century onward, including Chinese, Koreans, and Austronesians (Taiwanese indigenous peoples and Micronesians). It was later employed as race propaganda.

Etymology

After Japan’s surrender in World War II, the empire fell, and Japanese statistics have since counted the population by nationality rather than ethnicity. Early Chinese records referred to the people of Japan as Wajin (Wa or Wō) or Yamato, using a single Chinese character that originally meant "dwarf." This character was used until the 8th century, when the Japanese objected and replaced it with one meaning "harmony, peace, balance." That character was later adopted to refer to the country itself, often combined with the character for "great." The historical province of Yamato (now Nara Prefecture in central Honshu) borders Yamashiro Province (southern Kyoto Prefecture). Both names appear to contain the Japonic root yama, usually meaning "mountain(s)," though sometimes closer to "forest" in some Ryukyuan languages. Similar shared etymological elements appear in other province pairs, such as Kazusa and Shimōsa, or Kōzuke and Shimotsuke, thought to result from the subdivision of an earlier single province.

The origins of the name "Wa" remain uncertain. Chinese texts described an ancient people in the Japanese archipelago as ʼWâ or ʼWər. Scholar Carr surveys proposals for its etymology, ranging from feasible (transcribing Japanese first-person pronouns waga "my; our" and ware "I; we; oneself") to shameful (the "dwarf" character). He summarizes two main interpretations: "behaviorally submissive" or "physically short." The "submissive" explanation dates to the 121 CE Shuowen Jiezi dictionary, which defines the character as "obedient/submissive/docile appearance," with a "bent" phonetic.

Carr suggests that when Chinese first met Japanese, they may have transcribed Wa as ʼWâ "bent back," signifying compliant bowing—a gesture of respect noted in early records, such as squatting or kneeling with hands on the ground. Koji Nakayama interprets the character as "winding" meaning "very far away," euphemistically translating it as "separated from the continent." The second etymology—"dwarf, midget, little people"—has possible cognates in words for "low, short," "strain; bent legs," and "lie down; crouch." Early Chinese histories mention a "pygmy/dwarf country" south of Japan, possibly Okinawa or the Ryukyu Islands. Carr argues that the "submissive people" interpretation came first, with the "little people" legend developing later. After the Meiji Restoration, scientific racism was introduced from Western countries in the late 19th century.

Though hotly contested by Japanese intellectuals, the notion of racial homogeneity was used as propaganda due to political circumstances surrounding Japanese imperialism and World War II. Pseudoscientific racial theories, including belief in the superiority of the Yamato character, justified military expansionism, discriminatory practices, and ethnocentrism. The concept of "pure blood" as a criterion for the uniqueness of the Yamato minzoku began circulating around 1880, around the time some Japanese scientists started investigating eugenics. Initially, to justify conquest of continental Asia, Imperial Japanese propaganda claimed that the Japanese represented a combination of all East Asian peoples and cultures, emphasizing heterogeneous traits.
