Daily mythical creature 192: the Kazenbo [Japanese folklore; yokai]

(image source: Toriyama Sekien, 18th century)

There is a Buddhist ritual involving self-immolation that supposedly grants enlightenment and allows the user to become a Buddha after death.

Near the end of the 10th century, some monks set themselves on fire and died a gruesome death this way. However, there are stories about the Kazenbo, which appear as flaming humans or fiery humanoid ghosts that supposedly haunt graveyards, implying that not all of these monks managed to rest in peace after their self-immolation. In the area of Mount Toribe, this ghost apparently haunted Buddhist graveyards.

Also note the reverse swastika design on the lantern, which was a Buddhist symbol for luck and life long before it was used by the Nazi party. This is not a Nazi ghost, even though fiery undead Nazis sound like a great plothook for an action movie.

And the Gazu Hyakki Yagyo from Toriyama Sekien, I personally read the “Japandemonium” translation by Hiroko Yoda and Matt Alt
