This is Okuno-in Fudo-do Hall, which was built in the early Edo period (early 17th century). It is designated as a tangible cultural property by the Tokyo Metropolitan Government.
This hall is located at the far end of Yakuo-in Temple, and is a relocated Goma-do, which used to be the location of the main hall.
In the hall are enshrined a wooden Fudo Myo-o and Nidoji Ryuzo, both designated as Tangible Cultural Properties by the Tokyo Metropolitan Government.
At the back of the hall is the Fuji Sengen-sha Shrine, which is said to have once been the Okuno-in Hall.
The presence of this shrine indicates the deep connection between the faith of Mt. Takao and Mt Fuji.
