Border to beyond

There was a place which called "Sai no kawara" near the obelisk. It means the place where human go at first after died. If the dead is a child, he can't go both beyond and life, and must stay alone there forever. It was a penalty because he died before his parents die. In order to sorry them, many jizo statue were constructed there.
I didn't imagined such a strange place was there at 2,700 m height.
