Can cousins marry each other in Japan?

Cousin marriage is legal in Japan, but with restrictions. First cousins are allowed to marry only if they are both over 20 years old and have undergone genetic counseling. If the counseling reveals a high risk of genetic abnormalities, the couple may still marry but must agree not to have children together. The debate over cousin marriage in Japan is likely to continue for some time as it remains a complex and controversial issue with legal, cultural, and scientific considerations.

Question about Japan

Can Japanese siblings marry each other?

Incestuous marriages are illegal in Japan, and such relationships are generally frowned upon in Japanese culture due to violations of filial piety and social norms. Incestuous relationships can have severe psychological, genetic, and social implications for those involved, as well as impact family dynamics. While historical context exists for such relationships in Japan, they are no longer widely accepted or practiced. Siblings who wish to marry but cannot do so legally in Japan have the option of marrying in another country where such marriages are legal, but may face legal repercussions upon returning to Japan.
