Otogo Jinja

 At the top of the stairs I found this stone. I have no idea what the characters mean. I can't read the top one, the middle one means to speak humbly and the bottom one, if I am reading it correctly indicates a tower or pagoda.

 This is the altar and surprisingly it was open so I could see inside.

I assume that this is the young girl that is referred to in the shrine name. She seems to be holding Buddhist pray beads which brings to mind the reference to a pagoda in the first picture. However, it all remains a mystery at this point.
