gently sloping mountain; the less rugged of a pair of mountains
Used in contrast with 男山 (おとこやま), which refers to the steeper or more rugged mountain of a pair. Often appears in geographical names or descriptions of paired mountains.
See also: 男山
In this region, the gently sloping one is called 女山 and the steep one is called 男山.
Compound of 女 (おんな, 'woman') and 山 (やま, 'mountain'). The term likely derives from a metaphorical pairing of mountains, where the gentler slope is associated with femininity.
