後期古墳時代 (Late Kofun Period) refers to a historical era in Japan that lasted from around the 5th to the 7th century. This period is characterized by the construction of large burial mounds, known as 古墳 (kofun), which were built for powerful leaders and aristocrats. These mounds often contained valuable grave goods, reflecting the social hierarchy and cultural practices of the time. During the 後期古墳時代, Japan saw significant political and social changes, including the rise of the 大和政権 (Yamato state). This era also marked the introduction of 仏教 (Buddhism) and increased contact with the Asian continent, leading to cultural exchanges that influenced Japanese society.
