女人道は、高野山が1872年（明治5年）に女人禁制が解かれるまで、女性が高野山を参拝するため、高野山境内の周囲に置かれた女人堂を結ぶ巡礼路である。
高野山へ至る道は七本（高野七道）あり、それぞれの入口（高野七口）に女人結界が設けられ、女性信徒のための籠り堂として七つの女人堂が建てられた。
不動坂口の女人堂は、現存する唯一の女人堂で、正式には一心院谷女人堂と呼ばれていた。
特に、この女人堂は女性に人気があり、参詣者が多かったそうです。
The Nyonindo is a pilgrimage route that connects Nyonindo, which was placed outside the precincts of Koyasan, for women to visit Koyasan until the ban on women was lifted in 1872.
There are seven roads leading to Koyasan (Koya Shichimichi), and at each entrance (Koya Nanakuchi), a barrier for women was established, and seven Nyonindo halls were built as sanctuary halls for female believers.
Fudo Sakaguchi's Nyonindo is the only existing Nyonindo, and was officially called Isshinindani Nyonindo.
In particular, this Nyonindo was popular with women, and it is said that there were many pilgrims.
