I don't know if this was asked before but can someone clarify regarding what " married to a subject " mean is it like Sweden and Norway when princes of the royal blood weren't allowed to marry someone who is a Swedish or Norwegian.
If a Chris O'Neill married a princess of the imperial family would she retain her position and title or is it, commoners in general?
If a Japanese princess married a foreign prince, she could IMO hardly be stripped of her royal title as she is not marrying beneath her station.
Whether she will retain her place in the succession is another matter.
Probably not IMO. I think it would be expected of her to follow her foreign husband and settle abroad somewhere.
A princess who married a foreigner, prince or commoner, would be excluded from the imperial family and lose her imperial title.
The idea is that on marrying, a woman leaves the family of her father and joins the family of her husband. Marriage to a foreign prince would make the princess a member of the foreign royal family, excluding her from the Japanese imperial family.
The Imperial House Law of
1889 allowed the Emperor to authorize a woman who had left the imperial family to retain her imperial title, but the law also made marriages to foreign royals, and any commoners, impossible.
Article XLIV. A female member of the Imperial Family, who is married to a subject, shall be excluded from membership in the Imperial Family. However, she may be allowed, by special grace of the Emperor to retain her title of naishinnô or nyoô, as the case may be.
Article XL. Marriages of members of the Imperial Family shall be restricted to the circle of the Imperial Family, or to certain noble families specially approved by Imperial Order.
The Imperial Household Law (1889)
Under the (current) Imperial House Law of
1947, imperial titles are reserved for members of the imperial family. A princess may now (theoretically) marry a foreigner, but she cannot be allowed to retain her title after she has left the imperial family.
Article 5. The Empress, the Grand Empress Dowager, the Empress Dowager, Shinno, the consorts of Shinno, Naishinno, O, the consorts of O, and Jo-o shall be the members of the Imperial Family.
Article 12. In case a female of the Imperial Family marries a person other than the Emperor or the members of the Imperial Family, she shall lose the status of the Imperial Family member.
The Imperial House Law - The Imperial Household Agency
As for succession, Japanese princesses had no place in the line of succession under the law of 1889, nor in the current law of 1947.
