This study examined the effects of drawing yōkai using mixed methods. There were 16 participants in the experimental group, drawing “yōkai,” and 15 participants in the control group drawing “things at home.” All participants chose and decorated their favorite images to draw from 15 stimulus figures. To examine the differences in difficulty levels of drawing experiences and associated changes in emotions, a mood survey was administered before and after the drawing activity. An impression rating about their pictures and interview about the experience were also conducted afterwards. The results showed similar changes in mood pre- and post-activity in both groups, suggesting that the drawing activity itself may be calming. Members of the experimental group reported satisfaction more frequently than those in the control group. The experimental group was re-interviewed one week later to assess changes in their impressions regarding and (imagined) dialogue with the yōkai. Their narratives indicated deeper intimacy and self-insight, suggesting that the yōkai drawing method is a less-invasive way to promote insight.
