Stories of ‘yokai,’ supernatural or mythical beings, have been passed down for generations as a metaphor for the unknown, which is often associated with people’s sense of fear. Our workshop invited participants to create their own yokai that would be born out of the irritation they face in their daily lives. The aim of the workshop was to give participants an experience to objectively reflect on their annoyances by communicating them in the form of a yokai. We also hoped that participants would realize the social and cultural context behind our sense of anger. Judging from the feedback we received, we believe that the participants enjoyed creating their own yokai and that the workshop managed to actualize its goal of giving participants a chance to think about why they were irritated.
