Well, I’m not sure it’s “graffiti” exactly, at least in the sense of being vandalism, but it’s the kind of art style:
This graffiti painting is of komainu (at least I think it is). These are lion-dog statues that stand at the entrance to many Buddhist temples here in Japan. This drawing is at a local shop here in town, near one of my favorite restaurants. Just one of the many interesting artistic things around town!
