An Unsettling Mystery Has Washed Up On Japan's Shores.

An unsettling mystery has washed up on Japan's shores.

According to (CNN) Over the past two months, at least eight wooden boats have been found in the Sea of Japan on or near the coast, carrying a chilling cargo -- the decaying bodies of 20 people, Japan's coast guard told CNN.

All of the bodies were badly decomposed and
"partially skeletonized" -- two were found without heads -- and one boat contained six skulls, the coast guard said. The first boat was found in October, then a series of boats in late November.

Coast guard officials are now trying to unravel the riddle of where these ghostly boats came from and what happened to those on board.
