Geographical problems. The origin of yamato nation in Japan.

When the Yamato people came into being and where their ancestors came from have long been impossible to verify in faint epics and various legends. What is certain now is that as early as a certain time in BC, a continuous and growing migration to Japan began. Most of the immigrants are Huangpi Mongolians, mainly composed of Tunguses from Siberia and Northeast China, Malays from Nanyang Islands, Indosinians from Indochina Peninsula, Wuyue people from the lower reaches of the Yangtze River, and Han and Korean nationalities. They descended along the Korean peninsula, crossed the strait and boarded this volcanic archipelago at the end of East Asia, where the first light always rises. 1979, Kenzaburo Birishi, emeritus professor of anthropology in osaka kyoiku university, Japan, first published a new theory that "the birthplace of Japanese is in Yunnan Province, China". 1984 On February 23rd, Professor Niaoyuexian, who devoted himself to the study of social human culture, announced: "A field trip was made to the ethnic minorities in mountainous areas of Thailand (northern Thailand), which were thought to come from Yunnan, and it was found that all babies had birthmarks on their buttocks". Professor Bird Yuexian also emphasized this discovery: "The birthmark in Japanese constitution is from Yunnan, which is circumstantial evidence that this area is the birthplace of Japanese."
