The bit on history is quite helpful in understanding more about the culture of Japan now and then.

Wiki: Yurei by Wikipedia

Before the inevitable criticism of Wikipedia's open-source variation on encyclopedia writing, I feel it is important to emphasize how much more stringent (and cited) Wikipedia has become since its defamation in the early 2000's. That aside, this Wiki article explains a great deal about yurei, including history, classifications, and exorcism (a topic I did not cover).
