📖 Kofun Period

From the mid-3rd century to around the 7th century, the rulers began to construct "kofun," characterized by square front and round back burial mounds, marking a period known as the Kofun period. During the Kofun period, Japan saw the emergence of its first unified government, the "Yamato polity," which laid the foundation for the formation of the nation. This article will trace the historical flow to explore the establishment of Japan's first unified regime and the process of nation formation, as well as the lifestyle of the people at that time and the trajectory of cultural development.

Centered around the Great King, the "Yamato State" was established to unify the powerful clans across various regions. Immigrants from the Korean Peninsula (渡来人, torai-nin) brought with them the cultures, technologies, and political models of Korea and China. The trend of constructing ancient tombs known as "keyhole-shaped mounds" (前方後円墳, zenpōkōenfun) spread throughout the country.
