Hard to explain why I like it, since I am not sure what it means.
Somebody may paint it white again, so I may not see it again. In fact, I don't remember exactly where I it was.
But the memory of this street art is forever in my heart. Even if I loose this photo, I will probably never forget about the moment I first saw it.
I guess this artist can't even imagine he/she is making somebody in Tokyo very happy.
