The Abacus Makes a Comeback in the Reiwa Era: Ranked 6th in Extracurricular Activities, Student Numbers Double in a Year, and Why Middle-Aged and Older Adults Are Also Enthusiastic

In an era where calculators and AI are commonplace, Japan's traditional calculation tool, the "soroban" (abacus), is experiencing a resurgence in the Reiwa era. According to reports from TV Asahi, "soroban" has ranked sixth in the list of extracurricular activities for elementary school students, surpassing gymnastics and soccer. In newly established classes in Tokyo, the number of students has doubled within a year, with an increase of about 500 students across the group. This rapid growth is driven by the need to strengthen calculation skills for junior high school entrance exams, a reevaluation of the educational value of "analog × critical thinking" in the AI era, and a rising demand for brain training and well-being among middle-aged and older adults. Existing research also suggests the usefulness of soroban training in maintaining cognitive function in the elderly. Internationally, abacus education is supported as a form of "right-brain and working memory training," and Japan's renewed focus resonates within a global context.
