The Yamato state emerged in the 3rd century CE, consolidating power over neighboring clans. It developed a centralized authority, introduced Chinese writing, and adopted Buddhism. The Yamato clan expanded through military campaigns and alliances, establishing diplomatic relations with Korean kingdoms and China.

The Kofun period, spanning 300-538 CE, marked the transition from Yayoi to Asuka periods. It was characterized by massive burial mounds, social stratification, and technological advancements. The Yamato state played a crucial role in Japanese unification through centralization, standardization, and cultural assimilation.
