The Taishōgoto is a plugged-string-instrument invented in the Taisho period (1912–1926) in Japan and has gained great popularity among older adults. We studied three Taishōgoto groups with participants over the age of 70. The groups met twice a month, aiming to perform at concerts. Based on the survey, observations, and interviews, we found that the Taishōgoto was an ideal instrument for older adults, because it was easy to play, and an ensemble can be formed easily. A national network of Taishōgoto organizations provided an abundance of opportunities to perform locally and nationally, which was a main motivating factor for participants to improve and maintain their skills. Participants benefited by an “uplifting mood” and a “discovery in meaning of life,” which contributed to their quality of lifeQuality of life. Mid-pandemic follow-up interviews in late-2022 showed that two of the groups continued as usual, but the lack of public performances was demotivating.
