Culture of Japan

Japanese culture has changed greatly over the millennia, from the country's prehistoric Jōmon period, to its contemporary modern culture, which absorbs influences from Asia and other regions of the world.

Since the Jomon period, ancestral groups like the Yayoi and Kofun, who arrived to Japan from Korea and China, respectively, have shaped Japanese culture. Rice cultivation and centralized leadership were introduced by these groups, shaping Japanese culture. Chinese dynasties, particularly the Tang dynasty, have influenced Japanese culture throughout history and brought it into the Sinosphere. After 220 years of isolation, the Meiji era opened Japan to Western influences, enriching and diversifying Japanese culture. Popular culture shows how much contemporary Japanese culture influences the world.

There are two competing hypotheses that try to explain the lineage of the Japanese people.

The first hypothesis proposes a dual-structure model, in which Japanese populations are descendants of the indigenous Jōmon people and later arrivals of people from the East Eurasian continent, known as the Yayoi people. Japan's indigenous culture originates primarily from the Yayoi people who settled in Japan between 1000 BCE and 300 CE. Yayoi culture spread to the main island of Honshu, mixing with the native Jōmon culture. Modern Japanese have an estimated 80% Yayoi and 20% Jōmon ancestry.

The second hypothesis proposes a tripartite model of genomic origin. This hypothesis proposes that contemporary Japanese people are from three distinct ancestral groups: Jōmon, Yayoi and Kofun, with 13%, 16% and 71% of genetic ancestry, respectively. During the Kofun period, it is said that migrant groups from China came to Japan and settled on the island, bringing with them various cultural advances and centralized leadership. The migrants who came to Japan during the Kofun period appear to have had ancestry that mainly resembles the ancestry of the Han Chinese population of China. The Jomon people were hunter-gathers; the Yayoi people introduced rice cultivation; and the Kofun migrants introduced imperial state formation.

Japanese culture was influenced from ancient times to the Middle Ages primarily by multiple Chinese dynasties, with substantial derivation from the Tang dynasty, and to a lesser extent by other Asian countries. For example, one of the scripts for writing in the Japanese language is Chinese characters (kanji), but Japanese has no genetic relationship with Chinese. Since the Meiji era, Japan has been primarily influenced by Western countries.

The inhabitants of Japan experienced a long period of relative isolation from the outside world for over 220 years during the Tokugawa shogunate until the arrival of the "Black Ships" and the Meiji era.

Today, the culture of Japan stands as one of the most influential cultures around the world, mainly because of the global reach of its popular culture. In 2023, U.S. News & World Report ranked Japan's cultural influence as the highest in Asia and 4th worldwide.
