There are lots of foxes on the grounds of Fushimi Inari. One has a ball inside the mouth, others have key, scroll, rice ear, and nothing. The ball represents a treasure, and the key represents the way to get the treasure.
Many people were taking pictures of a stone-made fox a few days before. The reason was that a cat next to the fox was washing face and a raven perched on the branch behind was looking at us.
