Always, at this time of year, on TV you can see programs about hauntings, shinreishashin, etc... There is even a small book, sold in conveniance and book stores that is a guide to haunted places in the Kanto area.
I bought it last year and went to some places with a friend of mine, some were REALLY creepy! We could see and hear some WEIRD sh**:s07 , stuff that I still have nightmares about now
The main difference with Japanese ghosts and western ghosts is that Japanese ghosts almost always have some kind of "revenge" or evil intention (urami). Westend ghosts are almost weak in comparison.
