You can find many ghost tales in the Japanese storytelling tradition.
Research Tip: You can start with the Yurei article at Wikipedia, along with more specific articles like Onryo (vengeful spirits), Funayurie (ghost of those who die at sea), and so on; you will find many good links in the Yurei classifications section. You can find some useful books online too such as Ancient Tales and Folklore of Japan by Richard Gordon Smith and In Ghostly Japan by Lafcadio Hearn.
