For Families Concerned About Dementia
OTOKAI is an innovative cognitive wellness program that uses music to help prevent dementia. Participants use a dedicated app to listen to and compare AI-generated music inspired by a given theme, then create a musical work of their own. Classes are held once a week. Anyone can enjoy a simple music composition experience, and the creative process naturally stimulates the brain, helping maintain cognitive function.The program also encourages social interaction, helping participants discover new interests and build meaningful relationships while supporting dementia prevention.
OTOKAI classes are held once a week in small groups of approximately ten participants. Because online participation is available, people can join from anywhere in Japan.
Because ongoing participation is required, cognitive assessments are not included in one-time events.
