Assessment

Johann Hari claimed that Japan has 'statistically zero childhood obesity' and emphasized that this was 'not an overstatement.' However, official public health and demographic data from the Japanese government (MEXT, MHLW) and international bodies (WHO, OECD) show a clear, measurable non-zero prevalence of childhood obesity. Under MEXT school health surveys, obesity rates among 11-year-old schoolchildren consistently range between 8.7% and 11.8%. MHLW national health surveys record childhood obesity between 4.3% and 4.5%, and WHO/NCD-RisC datasets record age-standardized obesity among youth aged 5–19 at 3.0% to 4.5%. While Japan has one of the lowest childhood obesity rates among developed countries, it is not statistically zero.

Japan Ministry of Education, Culture, Sports, Science and Technology (MEXT) School Health Statistics Surveys show childhood obesity rates between 8.7% and 11.8% among 11-year-olds.
Japan Ministry of Health, Labour and Welfare (MHLW) National Health and Nutrition Surveys report childhood obesity rates of 4.3% to 4.5%.
WHO and NCD-RisC age-standardized data place childhood and adolescent (ages 5–19) obesity in Japan at approximately 3.0% to 4.5%.
