A group of school kids on a field trip. The hats help the teachers keep track of their students. There will be different groups of students out at the same time and they will have hats unique to their class. Next to the Ashi-yu there is a suggestion box shaped like the Ashi-yu.
The backpacks the children are wearing are outing backpacks and not the formal school backpacks that cost a small fortune. The formal backpacks are traditionally purchased for the children by the grandparents.
