"Mimi-katsu Walking" Attracting Attention in Dementia Prevention Research Mimi-katsu Walking is a new habit of walking while listening to audiobooks. It is drawing attention for its ability to solve problems such as "can't stick to exercise" and "don't have time to read" simultaneously. Furthermore, research conducted by Otobank and Kansai University of Social Welfare has shown that moving the body while listening to audiobooks can activate brain blood flow to the same extent as brain training for dementia prevention (※2). The Mimi-katsu Walking campaign was first held in 2023 and received positive feedback, and this year marks its 4th occurrence. Users who experienced Mimi-katsu Walking commented: "Normally I listen during my commute, but I started walking on weekends too, and it was fun." "It became an impetus to walk almost 10,000 steps every day." "By combining regular walking with reading by ear and making it a habit, I was able to lead a healthy life." We hope this campaign will be an opportunity to enjoy exercise and reading in this beautiful season of fresh greenery. ※2.
