Contrasting corners.

 I crossed the river by the bridge at the end of the park. Immediately on the other side of the river is an intersection and on the far left corner is this Shinto stele. Someone has left flowers as an offering.

On the far right corner, however, I found this. The yellow had is what first graders have to wear when going to and from school. So, I assume that this sign is warning drivers that young children may suddenly run out into the street. The raised hand is something that they learn to do in school. They are supposed to raise their hand to make themselves more visible to drivers. I'm not sure it actually does this, but it certainly makes the children more aware of traffic, which is a good thing in itseld.
