Haniwa ceramic from Japan. Source unknown. Wikipedia says:
The Haniwa (埴輪) are hollow terracotta clay figures which were made for ritual use and buried with the dead as funerary objects during the Kofun period (3rd to 6th centuries AD) of the history of Japan. Haniwa were created according to the wazumi technique, in which mounds of coiled clay were built up to shape the figure, layer by layer.
