Even after their husbands have passed away, Consorts of Imperial Princes and Princes are addressed in the same manner without adding the prefix 'Late' to the husband's name, for example 'Her Imperial Highness Hisako Consort to Imperial Prince Norihito.'
夫が「薨去」して未亡人となった場合でも、親王妃や王妃の称呼については「憲仁親王妃久子殿下」と、夫の名に「故」を冠さない。
