About the Program

OTOKAI is a dementia prevention program built around weekly music-creation lessons powered by artificial intelligence.

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.

Small-Group OTOKAI Lessons Available Online

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.

Typical Lesson Flow

Theme Presentation
A theme is presented through the app. Themes may include photographs, artwork, videos, haiku, poems, quotations, or other forms of visual and written expression.
2
Select AI-Generated Music
Participants enter words inspired by the theme and choose the AI-generated musical piece that best matches their imagination.
3
Presentation and Discussion
Participants present their work to the group, explain their choices, and receive feedback from the instructor.
4
Cognitive Assessment
Cognitive assessments are conducted before the program and again after six months to evaluate whether cognitive abilities have been maintained or improved.

Because ongoing participation is required, cognitive assessments are not included in one-time events.
