From a fellow Nara JET:
(Today is Setsubun, a day where Japanese children throw beans to keep demons out of the house. I asked my adult English students why demons didn't like beans, and they didn't know why. I then asked them to make up the basis for other holiday traditions. When I asked why they thought we hung stockings for Santa, one of my students said, "Fetishism?")
I will be attending this festival tonight.
