Japan is full of ghosts: Visiting the grave of Taira no Masakado's head soranews24.com

Though it’s not exactly a shinrei spot (a place where ghosts have allegedly appeared), Taira no Masakada Kubizuka is one of the most famous “ghost” spots in Japan.
It’s where Taira no Masakada’s head was enshrined in order to quell his spirit…because people believed it was wrecking havoc on the capital!
That was the day he was beheaded after starting the Taira Masakado Insurrection, which lasted only 59 days from the year 939 to 940.
Though the head apparently landed in several places, it is most famously enshrined in Otemachi, not far from Tokyo Station.
A number of calamities were plaguing the people of the area, and the disasters were blamed on the spirit of Taira no Masakado.
