Ten same-sex couples will file a lawsuit against the Japanese government in a bid for recognition towards marriage equality. The couples, who will file a joint lawsuit in February, reportedly argue that Japanese law doesn’t put into consideration the equal rights of same-sex couples and should be amended accordingly. Article 24 of Japan’s Constitution states that “marriage shall be based only on the mutual consent of both sexes.” Lawyers for the couples argue that the wording means that marriage equality should be officially recognised.
