Pink Tentacle links to a creepy, but very artistic, collection of Japanese ghosts in the spirit of the season:
Japan [has a] centuries-old tradition of swapping ghost stories [in the summer]. Some argue that the fear induced by a spine-chilling story can actually lower oneâ€™s body temperature, making it a great way to deal with the summer heat.
And if you click on the link to Pink Tentacle, you will find out all you need to know about . . . Severed Mouth Woman, who "sparked a mass panic in Japan in the late â€™70s and early â€™80s."
