In a broad sense, Dulai is the appellation of ancient Japan (formerly known as Japan) for overseas immigrants from the Asian continent such as North Korea and China. These people who migrated to Japan from other places are called "Dulairen" by archaeologists, but they are still mainly called immigrants from East Asia. Due to frequent civil wars or cultural exchanges, Dulai people usually move to Japan. These highly civilized Dulai people introduced farming technology, civil construction technology, as well as firing pottery, forging iron, textiles and so on. It was called naturalization before the war. These people like to call themselves descendants of Qin Shihuang or Emperor Gaozu. There are also two kinds of people crossing the river, one is the people crossing the river in the Qin and Han Dynasties, and the other is the new talents. Most of them were Han Chinese. After Le Lang County and Daifang County were captured, they were forced to emigrate to Baekje and Japan.

Rice culture was introduced into Japan during the Yayoi period. Although rice was planted in the late Sasaki era in Japan, it really began to spread, and it did not spread rapidly in the Japanese archipelago until the third century BC. Banjin, located in Fukuoka, Kitakyushu, is a relic of early rice cultivation during the Yayoi period.

In the ancient grave era, the great powers had frequent contacts with countries on the Korean Peninsula. In 552 AD, King Baekje sent an envoy to the imperial court of a big country, bringing with him Buddha statues and Buddhist classics, and Buddhist culture was also introduced to Japan. After Buddhism was introduced into Japan, it became one of the main religions in Japan and a part of Japanese culture today. The Yamato Imperial Court allowed these tourists to live in Feng Jingen, and the civilization brought by tourists greatly changed the Japanese way of life. Later, after entering the Asuka period, many Japanese royal officials believed in Buddhism, such as Shoto Kutaishi and Suwomazi, and devoted themselves to promoting Buddhism. The reason why Baekje people went to Japan was that Japan asked Baekje for craftsmen and doctors of the Five Classics in order to avoid Koguryo.

Baekje and Koguryo on the Korean peninsula were destroyed by the Tang and Xin allied forces after the Battle of Baijiangkou. Many Baekje believers fled to Japan and were protected by the Yamato court. Descendants of Baekje royal family spread Baekje royal system in Japan.
