Original report
The Seaside Monkey is a monkey cryptid reported from Japan.
Description
In 2003, a person posted in the occult topic of "2ch," a Japanese Internet forum, that he had seen strange creatures in the past. According to him, when he was a junior high school student living in a city by the sea, he encountered a strange creature sitting on a guardrail post on his way home one rainy day. It was a hairless monkey-like creature with light blue skin and a face resembling a golden snub-nosed monkey.
The creature initially ate oranges, but when it noticed the witness, it threw orange peels at him, so he swung his bag around and threatened the monkey. The monkey-like creature was startled by this action, jumped into the sea, dove and disappeared.
Explanations
The only monkey originally living in Japan is the Japanese macaque. There are other monkeys brought from abroad that have established themselves in some areas, but they are all closely related to the Japanese macaque, so their appearance is not so different.
The Japanese macaque is usually found in the mountains and seldom appears along the coast. Some populations may appear near the sea, but they are by far the minority. Even in these cases, they do not willingly engage in diving behavior.
Therefore, both this creature's appearance and behavior are very different to the monkeys known scientifically in Japan.
