What was the maritime traffic line in ancient Japan?

Summary: There were roughly three maritime traffic routes in ancient Japan.

The first is the maritime trade route between Japan and North Korea.

The second is the maritime trade route between Japan and China.

The third is the maritime trade route between Japan and Southeast Asian countries (including the Pan-Pacific Islands).

Later, with the development of navigation technology, the fourth maritime transport was born, which is the trade route between Japan and Europe (Netherlands and Portugal).

Maritime strategic communication lines are of great significance for national strategic material transportation, large-scale foreign trade and trade activities with strategic influence, and ensuring the strategic mobility freedom of maritime combat forces.

Ancient Japanese culture: Ancient Japanese culture mainly benefited from the absorption and integration of China culture. Japanese absorption of China culture is a long-term historical process in many aspects. Chinese characters and Chinese, Confucianism, statutes and Buddhism are the main contents of Japanese absorption of China culture.

It was under the great influence of Chinese civilization that it went through the barbaric stage and entered the stage of civilization in the 4th and 5th centuries. In the Han Dynasty, four counties were established on the Korean peninsula, and a large number of Han Chinese immigrated from Korea to Japan. During the reign of Emperor Xionglue (457-479), there were as many immigrants from mainland Japan as18,000.
