. Other names include or . Little is known of the origin of ''umibōzu'' but it is a mythical sea-spirit creature and as such has multiple sightings throughout Japan. Normally, ''umibōzu'' appears to sailors on calm seas which quickly turn tumultuous. It either breaks the ship on emergence or demands a bucket or barrel from the sailors and proceeds to drown them. The only safe way to escape an ''umibōzu'' is to give it a bottomless barrel and sail away while it is confused.


Concept

They appear and disappear in the oceans, often at night, and it is thought that they would suddenly appear on what was previously a calm sea surface as a giant's black '' bōzu'' head and destroy ships. They are often a few meters (yards) to a few tens of meters (yards) in length, so they are seen as quite large, but there are also tales about relatively small ones. Like ''

s, and often the difference between them is not clear. They would say "lend me a ladle," and sometimes the ''funayūrei'' that come to sink ships are considered the same as ''umibōzu''. However, unlike the ''funayūrei'' who come with stormy weather, ''umibōzu'' sometimes appear at seas with no abnormalities (and in this case, once the ''umibōzu'' was seen, the weather would start getting stormy), so it's pointed out that these could be things that do exist but were misinterpreted. Some examples of things that could have been misinterpreted include sea organisms,

Also, ''umibōzu'' would often come in swarms as naked ''bōzu''-like beings and attack ships, and they would do things such as cling on to the hull and scull as well as put out the basket fire. It is said that they would sometimes let out a voice saying "yaa yaa" while swimming, and when hit with the scull would let out shrieks of "aitata". Their weakness is tobacco smoke, and it is said that if one is unlucky enough to encounter one, having one of those ready can lead to being saved.

Similarly, there is a legend about a "zatō gashira" (blind man head), a blind bōzu that appears above the sea, and it would ask people, "Am I fearsome?", and if one acts scared by saying, "I'm scared", or "Please help", it would say, "You should not be going out to sea at the end of the month", and disappear.

and a boatman named Zenchi refused to have "just one woman" on, so he forcefully took his wife on the boat, and it encountered a large storm. The shipowner believed that the dragon deity was angered, at least partly due to the women on board, and despite throwing into the sea things that he thought a dragon might like, the storm still did not calm, and finally, the kuro nyūdō appeared. It had a head five to six times the size of a human, glittering eyes, and a horse-like mouth that was in length. It is said that Zenchi's wife made her resolve and tossed herself into the ocean, and the kuro nyūdō gulped down that woman, upon which the storm stopped. These ''umibōzu'' are said to be fallen dragon deities who would demand sacrifice.

to fish for tuna, when the boat's long line was suddenly cut, and a large creature surfaced from the water. It had many grey-brown wrinkles on its body and eyes that were about in diameter, a collapsed nose, and no mouth to be seen. Half its body was submerged in murky water so its whole body could not be ascertained, but it was said to leave a trail. It is said that as they got ready to harpoon it, the monster disappeared into the sea. When an officer of the research lab, the Enyō Suisan Kenkyujo, at branch office in Yaizu heard of this account, he supposed that it was likely that the fishermen were mistaking an organism, such as a fish or whale, for a monster. In another eyewitness account, the half of its body that appeared from the water surface was about in length, so by inferring that its whole body was several times that length, they said that they never heard of an organism like that.

Similar creatures

In China, there is the legend of the ''kikokutan (鬼哭灘) no kai'', and according to research, it is said to be related to Japan's ''funayūrei'' and ''umibōzu'', but it has a different appearance. It is thought that when a boat goes on the sea above a ''kikokutan'', its appearance was described by the words 没頭, without a head, 隻手, having one hand, and 独足, having one leg, and it was short, and the bald monster would attempt to overturn the ship (on having no hair, this part of their appearance is the same).


Origin

The origin of ''umibōzu'' is unclear as there are no stories referencing what caused its creation or its first appearance. One theory is that they are the spirits of dead priests who were thrown into the ocean by Japanese villagers for some reason or another. Because their bodies have nowhere to be laid to rest, their souls inhabit the oceans and haunt it in the shape of a dark shadow, reaping its revenge upon any souls unlucky enough to come across it.


Attributes

In the early Edo period scroll '' Bakemono no e'', ''umibōzu'' is shown to have a shaved, smooth head and appears to be all black but it also looks like a mix between a dog and possibly a sea serpent and an octopus (see image). Its arms end in what resembles hand made up of five tentacle-like appendages constituting a hand. It also has a longer body with fins running down its spine as the lower body disappears underwater, once again obscuring our view of its lower body and continuing the mystery of what its lower body looks like. Similar to most legends, the eyes are opened wide and it is smiling. There are two tentacle-like appendages coming from its face which could be feelers of some sort. This is the only occurrence of these feelers and they do not appear in any other legends or accounts. The presence or sighting of an ''umibōzu'' is widespread and not an uncommon occurrence. It appears as a large, black humanoid figure that only ever rises from the ocean to about its waist, never revealing its lower half. According to most accounts, no one knows what the lower half of an ''umibōzu'' looks like and thus this figure is shrouded in mystery. Some posit it has tentacles like an octopus while others suggest it is purely humanoid and has two legs like the monks and Buddhas it resembles. The humanoid figure generally appears to be up to tall, but can come in a variety of sizes. The sheer size of the ''

or any type of religion in most ''umibōzu'' legends which seems strange. Normally, if a ''yōkai'' looks a certain way it is to accomplish something specific to the spirit but ''umibōzu'' seems to have no ties to Buddhism in anything beyond its appearance. Some accounts suggest ''umibōzu'' appear to be praying and constantly smiling while their two, round eyes are opened wide in a constant stare. One common theme in every account is the eyes which seem to pierce the sailors and stands out in stark contrast with the black void of its skin. Some accounts suggest ''umibōzu'' has two arms like a human and others suggest they resemble tentacles like that of an octopus.


Manifestations

''Umibōzu'' always appear only in the ocean, usually during peaceful waters and fair weather. These fair conditions would normally put the sailors at ease as they are literally "sailing on smooth waters" but the possible presence of a malicious spirit put many sailors on edge in these times of peaceful sailing. Upon its sudden rising from the ocean, causing waves and sometimes flipping ships or breaking them with its emergence, ''umibōzu'' is accompanied by the winds begin to blow and waves toss the ship about. The appearance of an ''umibōzu'' alone causes this dramatic shift in weather which puts any ship in immediate peril, not only from being capsized by the waves but also from being crushed by the ''yōkai''. This could be a mixing of the ''

'' legends which suggests these ''yōkai ''appear during storms at sea. With very few first person sightings which are recorded or passed on, ''umibōzu'' tends to have characteristics with other ''yōkai''. Similar to the ''funayūrei'', ''umibōzu'' either breaks the ship with its arms or it demands a barrel from the sailors which it consequently uses to drown the sailors by scooping up water and dumping it into the ships deck. ''Funayūrei'' use ladles to drown sailors in some Japanese legends while some accounts of ''umibōzu'' claim it appears with a ladle for the same purpose. The only way to escape from an ''umibōzu'' safely is to give it a bottomless barrel, such that it cannot scoop up water, thereby giving the sailors a chance to escape. While it is confused and attempting to scoop up the water in a futile effort, the sailors have just enough time to sail away to safety. The ''yōkai'' seems to be foolish in the way it does not understand why it cannot scoop water with the bottomless barrel, possibly showing the superiority of humans over ''yōkai'' in general. Normally, a chance encounter with ''umibōzu'' is deadly for all and as such there are very few instances of first-person accounts of an ''umibōzu'' encounter. Any survivors of such an encounter are due to their giving a bottomless barrel or if there were a shipwreck survivor adrift in the ocean who washed ashore. Usually called the "sea monk" (''umi'' means sea and ''bōzu'' means monk), ''umibōzu'' has no ties to religion in any of its actions or sightings. Victims of this ''yōkai'' are random and have no ties to any action or belief. Sailors who were attacked were of no specific sect or religion as they are only ever described as pitiable sailors, the victims of an attack.
