Yokai Inujima
Inujima, an island floating in the Seto Inland Sea. About 100 years ago, a copper refinery operated on this island, and the black sand called copper dross discharged from it still remains on the island today. Copper dross is a byproduct of the copper refining process and was originally produced as industrial waste.
Yokai Inujima is a three-dimensional work created with the concept of embedding this black sand into the eyes and breathing new life into it.
