I'm jumping on this subject to ask you a question mona_jpn:
I've realized that, in many Japanese recent fictions like "The ring", "Dark Water", "The grudge" or even "The host", a common link with Hanako-san is present. There seem to be a common picture of ghosts represented by a girl, most of the time a seemingly "drowning"-like girl, with dark wet hair hiding her face, and often wet dirty clothes.
Or, at least, there seem to be an extreme fear of water with water-like creatures.
In your opinion, why is there that fear of "drowning girl" in Japan ?
Is there a peculiar lasting myth about it in the japanese mind, aside from hanako-san ?
