If you're a scuba diver, you've probably heard of the Truk Lagoon. Located halfway between the Philippines and Hawaii near the Chuuk Islands, this lagoon offers some of the best wreck diving in the world. Once the site of a decisive battle between Japan and United States during World War II, there are numerous ships, planes, tanks, and submarines that have been resting here since they were shot down nearly 70 years ago. Now, divers and locals claim that the ghosts of these soldiers haunt the waters around the wreckage. In northern Japan, you'll find many children's lunchboxes decorated with a cute, green reptile on the side. That animal, called a Kappa, was once feared as an evil cross between a demon and a turtle before it became something of a national mascot. Recently, however, a new spate of ominous sightings has given rise to rumors that the Kappa has returned and is responsible for missing livestock and even children.
