Haniwa are ancient clay figures that were created in Japan during the Kofun period, which lasted from around the 3rd to the 7th century. These figures were typically placed on top of burial mounds, known as kofun, to serve as offerings or to protect the deceased in the afterlife. Haniwa come in various shapes, including human figures, animals, and objects, reflecting the culture and beliefs of the time. The production of Haniwa involved hand-molding clay, and they were often decorated with intricate designs. Over time, the style and purpose of Haniwa evolved, but they remain significant artifacts that provide insight into ancient Japanese society, rituals, and artistic practices.
