APPEARANCE: When the ghosts of people who have died at sea transform into vengeful spirits, they become a particular type of ghost called a funayūrei. They are the shadows of drowned sailors, remaining in this world to find their former friends and comrades, to bring them down into the sea with them. Like many ghosts, funayūrei usually appear as dead bodies wearing white funerary robes. They can be seen at night, when the moon is new or full, or on particularly stormy or foggy nights, especially during Obon. They appear as an eerie, luminescent mist at first, which gets closer and closer until it forms into a ship with a ghostly crew.

INTERACTIONS: Funayūrei ghost ships attacks in different ways, sometimes charging headlong towards the other ship, causing it to steer away so sharply that it capsizes, other times carrying a ghostly crew who cling to the side of the other ship and try to drag it down under the water. The ghosts themselves carry large ladles and buckets which they use to fill ships with seawater, sinking them and adding more souls to their crew. Occasionally funayūrei strike not as a large crew of man-sized ghosts, but as one very large ghost who rises out of the water to capsize a ship immediately. This ghost often demands a barrel from the crew, which it uses to flood the deck and sink the ship. These giant funayūrei are often confused with umi-bōzu, which appear and attack in a similar manner.

It is said that a clever crew can outsmart the funayūrei by carrying buckets and ladles with holes in the bottom, so that despite their efforts the ghosts will not be able to flood the ship. Encounters with ghost ships can also be avoided by boldly sailing directly through the phantasm instead of turning to avoid a collision – though this runs the risk that the other ship may actually be a real one and not a phantasm. Some crews have also escaped the funayūrei’s wrath by throwing food and provisions overboard as offerings to the hungry ghosts, who chase after the food instead of the crew.
