Benefits of Common Cultural Traits in Japan and Korea
States like Japan and Korea benefited from having common cultural traits in various ways during the era in question. Common cultural traits facilitated trade, diplomatic relations, and cultural exchanges between Japan and Korea. The exchange of artisans and craftsmen, as well as the introduction of Buddhism to Japan and the adoption of Confucianism and Chinese-influenced written language, were significant outcomes of this cultural symbiosis.
