The coimagination method is a method for the prevention of dementia in which “a group of 3-6 people brings materials such as photos and discussion topics on a decided theme, and the speaker and listener take turns on the specific time to share their thoughts and feelings.”
This coimagination method requires a moderator who provides the topic and manages the time. By Bono-chan taking the role as a moderator in the group conversation, there are the advantages such as “people in the group can take turns in discussions in a well-balanced manner”, and “the conversation time can be managed without discomfort and even a laughter may break out”. Furthermore, it eliminates the need of accommodating a moderator and makes it possible for more groups to participate in the coimagination method with small numbers of human moderators.
