So, about a hitobashira(a human sacrifice practise from ancien japan)

So, I have to clear this first: I don´t support any actions of human sacrifice and that is not what this thread is supposed to be. I don´t want people to get the wrong idea that I somehow want to sacrifice some poor fool. Now that is out of the way, here is my question:
Have any of you necromancer or practisioners of death magick called upon any shades from the japanese gods? Any places that you know that have a connection to hitobashira?
