I'm looking for information on Japanese curses. Particularly the ones that can kill and linger for generations, but anything that can harm is OK. I've searched Japanese curses, Japanese supernatural curses, Japan curses, Japan cursed places and related terms, but somehow I always turn up "The Grudge" or some J-horror film. Cursed places, or how places become cursed are OK, too.
The setting of the story is in Japan, modern time, but it does go back in the past every now and then, so timeline isn't really a big thing.
Any help is welcome. :D Thanks for your time.
(and yes, this is for a Ghost Hunt fic)
