Not sure what this monument stood for; but it was really cool to see. Stood right next to the Osaka Castle, and had a bunch of kids standing around doing chants that day.  NOt sure why (everyone else thought it was weird too–the Japanese people were giving them a wide berth), but they were hollering chants and what sounded like pig-calling noises (Suey…Suey).  You can see two of them at the bottom.
