The article explores whether the Japanese population is getting taller or not. Historical records show that malnutrition, poverty, and disease prevalent during the early 20th century resulted in an average height of around 155 cm for men and 147 cm for women. However, improvements in nutrition and access to healthcare after World War II led to an increase in height among the Japanese population. The average height of Japanese men is around 172 cm, while women have an average height of around 158 cm today. Factors such as genetics, environment, lifestyle choices like exercise, and immigration also play a role in determining height. Continued focus on healthy eating habits and exercise routines will positively impact the physical attributes of future generations in Japan.
