How to say "duchess" in Japanese

Choosing the right word
  • 公爵夫人こうしゃくふじん
    nounCovers the sense of 'duchess' as a woman holding the rank of duke's wife or a noblewoman of ducal standing; it is the typical word for the title itself, though less common overall.
  • 公妃こうひ
    nounMeans 'duchess' only in the consort sense — the wife of a duke (or prince) viewed as his consort — and is a less common word; for the rank or title of duchess it is seldom the word you want.

公爵夫人 is the straightforward way to say a duchess, while 公妃 emphasizes the woman as a consort of a duke or prince; choose based on whether you mean the noblewoman herself or her role as consort.
