noun
priestess; female priest
Refers to a woman who performs sacred rites in a religious context. The term is straightforward and neutral.
彼女は神社の女司祭として働いている。
She works as a priestess at the shrine.
巫女 refers specifically to a Shinto shrine maiden or medium, often a younger woman performing ritual dances, whereas 女司祭 is a broader term for a female priest in any religious tradition.
Compound of 女 (おんな, 'woman') and 司祭 (しさい, 'priest'). The reading おんなしさい is a straightforward combination of the two components.
