Can a 16-Year-Old Marry a 20-Year-Old in Japan?

In Japan, the legal framework around marriage has evolved, but certain age thresholds remain in place. As of 2022, the Civil Code was revised to raise the age of majority from 20 to 18, aligning with broader legal reforms. This change also impacted marriage laws.

Under Japanese law, the minimum age for marriage is 18 for men and 16 for women. However, individuals under 20 are considered minors and require parental consent to marry. So, while a 16-year-old girl is legally allowed to marry, she must have approval from at least one parent or legal guardian. The same applies to a male partner under 18, though in this case, the 20-year-old would not need consent.

This gender difference in minimum marriage age has long been debated. Critics argue it reflects outdated gender norms, and there have been growing calls for equalizing the age limit at 18 for both sexes. While the 2022 reforms brought the legal age of adulthood down to 18, the marriage age for women remained at 16 — a compromise that maintains tradition while modernizing other aspects of civil law.

In practice, early marriages are rare in Japan and often attract social and legal scrutiny, especially when there’s a significant age gap. Authorities may investigate to ensure the marriage is consensual and not exploitative. Cultural attitudes also tend to discourage marriage at such a young age, with most Japanese couples marrying in their late twenties or later.

So while legally possible, a marriage between a 16-year-old and a 20-year-old is uncommon and subject to both legal and societal checks.
