Yesterday, February 3rd, it was setsubun day here in Japan, which supposedly marks the end of the winter (a little bit early) and the entrance of spring. According to tradition, on setsubun day you have to scare the demon spirits away and eliminate all the bad things that happened the former year.
One of the rituals consists on throwing beans to somebody who portrays an Oni (demon). The demon has to dance and pretend to be escaping while no being able to do it. In my company we made the ritual with Maruyama-san portraying the oni/demon while we threw beans at him (you can’t really see them on the video).
