Japan's age of consent is 13 years old, which is significantly lower than the average age of consent in other developed countries. The reasons behind this phenomenon include cultural factors such as a strong emphasis on respecting authority and hierarchy, historical factors such as feudalism and early marriage laws, the sexualization of children in Japanese media and culture, legal protection for minors, parental consent laws, rising age of marriage, international pressure, acceptance of large age gap relationships between older men and younger women, religious factors emphasizing adherence to social norms, and concerns related to gender equality.
