This article looks at the average height for a 14 year old Japanese girl, which is 152 cm (4 feet 11 inches), slightly shorter than the global average of 154 cm (5 feet 0 inches). Factors that influence this height include genetics and heredity, nutrition and diet, exercise and activity levels, and environmental factors such as access to healthcare or pollution levels. Genetics play an important role in determining height, with taller parents tending to have taller children. Nutrition provides essential nutrients needed for growth and development during childhood and adolescence. Exercise helps strengthen bones and muscles which can result in increased stature over time. With adequate nutrition and physical activity combined with good healthcare access rates throughout Japan, it is likely that the average height will remain stable over time.
