Haniwa are terracotta figures made during the japanese Kofun period (300-600 A.D. approx.) for ritual uses and as funerary objects. And they were the inspiration for Animal Crossing series gyroids!
The ones I made feature two dancers and are one of the most famous haniwas all over Japan. You can see them on display in Tokyo National Museum.
There are 3 types, freshly made, already dry and metallic (based on a concept made la few years ago for a class assignment).
