Did the Japanese in the Qin Dynasty begin to appear at that time?

The Japanese did not appear from the Qin Dynasty, but in the Neolithic Age.

Japanese islanders began to live on Japanese islands in the Neolithic Age. The earliest Japanese residents were Tungusic people who moved in from the northern mainland, and later Malays crossed the sea from the south. Since the second half of 5000 BC, China and Koreans have been migrating to Japan.

Japan's Neolithic Age to the 2nd century BC is known as the age of rope culture in archaeology. Stone tools and bone tools were used for hunting and fishing, and female clay dolls were unearthed in vertical caves.

In the 5th century, Yamato unified Japan. Immigrants are mostly yellow-skinned people, mainly composed of Fuyu people, Han people, Altai people and rope scholars from the Japanese archipelago during the Yayoi period (300 BC-250 AD).

Immigrants from the East Asian continent crossed the ocean, went south along the Korean peninsula, crossed the strait, and boarded this volcanic archipelago at the end of East Asia.

Xu Fufeng went to Japan on the orders of Qin Shihuang;

In 2 10 BC, Xu Fufeng was ordered by Qin Shihuang to lead "3,000 boys and girls" and "100 workers", carrying "five-grain seeds", to cross the sea by boat in search of medicine for immortality.

In Japanese historical documents, there are countless records about Xu Fudong's crossing the sea in Japan. Japanese scholar Xiao Ye Yukio verified that Xu Fudong's main activity areas after crossing were Kyushu and Kumano in Japan. According to the research of Mr. Masaichi Suzuki, a researcher of Fuji ancient books, Xu Fu died at the age of 70.

According to the statistics of Mr. Peng, a scholar in Taiwan Province Province, there are more than 50 tombs, temples, monuments, palaces, temples, temples and other sites related to Xu Fu's name, more than 20 landing sites and more than 30 legends and stories. Although these relics and legends are not all true, they are also related to historical facts.

Xu Fu led thousands of people to Japan, bringing China's advanced farming methods, all-round technology and customs and culture there, which enabled Japan to quickly leap from the Neolithic Age to the Bronze and Iron Age, or from the rope pattern age of fishing and hunting economy to the yayoi age of farming economy.

The popularization of rice, sericulture and medicine has promoted the great development of Japan's economy and culture. In Japan, Xu Fu is regarded as the god of agriculture, sericulture and medicine.
