Some people said some of Kazunomiya's poems after she moved to Edo, compared with the ones she wrote while she was in Kyoto, were not elegant at all, it was almost like someone else wrote the poems for her (it is said the poems were not even professionally written, her style changed into an unprofessional, dull style all of a sudden), there was a theory that someone was acting as a double in place of Kazunomiya.
在京の頃の歌風と比べ、東下後の歌風は、「雅」がまるで感じられず、まるで別人に取って代わったと言ってもいいような変化（それも、素人あるいは、一般庶民のような野臭い歌風に急変したとする）であるため、それをもって、替え玉であると言うことを唱える人もいる。
