The Japanese Identity
Just who are the Japanese? Where did they come from and when? The answer are difficult to come by, though not impossible--the real problem is that the Japanese themselves may not want to know.

UNEARTHING THE ORIGINS OF THE JAPANESE IS A MUCH HARDER TASK THAN YOU MIGHT GUESS. AMONG WORLD POWERS TODAY, THE JAPANESE ARE THE MOST DISTINCTIVE IN THEIR CULTURE AND ENVIRONMENT. THE ORIGINS OF THEIR LANGUAGE ARE one of the most disputed questions of linguistics. These questions are central to the self-image of the Japanese and to how they are viewed by other peoples. Japan's rising dominance and touchy relations with its neighbors make it more important than ever to strip away myths and find answers.

The search for answers is difficult because the evidence is so conflicting. On the one hand, the Japanese people are biologically undistinctive, being very similar in appearance and genes to other East Asians, especially to Koreans. As the Japanese like to stress, they are culturally and biologically rather homogeneous, with the exception of a distinctive people called the Ainu on Japan's northernmost island of Hokkaido. Taken together, these facts seem to suggest that the Japanese reached Japan only recently from the Asian mainland, too recently to have evolved differences from their mainland cousins, and displaced the Ainu, who represent the original inhabitants. But if that were true, you might expect the Japanese language to show close affinities to some mainland language, just as English is obviously closely related to other Germanic languages (because Anglo-Saxons from the continent conquered England as recently as the sixth century A.D.). How can we resolve this contradiction between Japan's presumably ancient language and the evidence for recent origins?

Archeologists have proposed four conflicting theories. Most popular in Japan is the view that the Japanese gradually evolved from ancient Ice Age people who occupied Japan long before 20,000 B.c. Also widespread in Japan is a theory that the Japanese descended from horse-riding Asian nomads who passed through Korea to conquer Japan in the fourth century, but who were themselves--emphatically--not Koreans. A theory favored by many Western archeologists and Koreans, and unpopular in some circles in Japan, is that the Japanese are descendants of immigrants from Korea who arrived with rice-paddy agriculture around 400 B.C. Finally, the fourth theory holds that the peoples named in the other three theories could have mixed to form the modern Japanese.

When similar questions of origins arise about other peoples, they can be discussed dispassionately. That is not so for the Japanese. Until 1946, Japanese schools taught a myth of history based on the earliest recorded Japanese chronicles, which were written in the eighth century. They describe how the sun goddess Amaterasu, born from the left eye of the creator god Izanagi, sent her grandson Ninigi to Earth on the Japanese island of Kyushu to wed an earthly deity. Ninigi's great-grandson Jimmu, aided by a dazzling sacred bird that rendered his enemies helpless, became the first emperor of Japan in 660 B.c. To fill the gap between 660 B.c. and the earliest historically documented Japanese monarchs, the chronicles invented 13 other equally fictitious emperors. Before the end of World War II, when Emperor Hirohito finally announced that he was not of divine descent, Japanese archeologists and historians had to make their interpretations conform to this chronicle account. Unlike American archeologists, who acknowledge that ancient sites in the United States were left by peoples (Native Americans) unrelated to most modern Americans, Japanese archeologists believe all archeological deposits in Japan, no matter how old, were left by ancestors of the modern Japanese. Hence archeology in Japan is supported by astronomical budgets, employs up to 50,000 field-workers each year, and draws public attention to a degree inconceivable anywhere else in the world.

Why do they care so much? Unlike most other non-European countries, Japan preserved its independence and culture while emerging from isolation to create an industrialized society in the late nineteenth century. It was a remarkable achievement. Now the Japanese people are understandably concerned about maintaining their traditions in the face of massive Western cultural influences. They want to believe that their distinctive language and culture required uniquely complex developmental processes. To acknowledge a relationship of the Japanese language to any other language seems to constitute a surrender of cultural identity.

What makes it especially difficult to discuss Japanese archeology dispassionately is that Japanese interpretations of the past affect present behavior. Who among East Asian peoples brought culture to whom? Who has historical claims to whose land? These are not just academic questions. For instance, there is much archeological evidence that people and material objects passed between Japan and Korea in the period A.D. 300 to 700. Japanese interpret this to mean that Japan conquered Korea and brought Korean slaves and artisans to Japan; Koreans believe instead that Korea conquered Japan and that the founders of the Japanese imperial family were Korean.

Thus, when Japan sent troops to Korea and annexed it in 1910, Japanese military leaders celebrated the annexation as "the restoration of the legitimate arrangement of antiquity." For the next 35 years, Japanese occupation forces tried to eradicate Korean culture and to replace the Korean language with Japanese in schools. The effort was a consequence of a centuries-old attitude of disdain. "Nose tombs" in Japan still contain 20,000 noses severed from Koreans and brought home as trophies of a sixteenth-century Japanese invasion. Not surprisingly, many Koreans loathe the Japanese, and their loathing is returned with contempt.

What really was "the legitimate arrangement of antiquity"? Today, Japan and Korea are both economic powerhouses, facing each other across the Korea Strait and viewing each other through colored lenses of false myths and past atrocities. It bodes ill for the future of East Asia if these two great peoples cannot find common ground. To do so, they will need a correct understanding of who the Japanese people really are.
