Akugyo
From Wikipedia, the free encyclopedia
Akugyo (悪魚 or 悪樓, "evil fish") or daigyo (giant fish) or raichōgyo (thunderbird fish) is a type of sea monster or aquatic yōkai in Japanese mythology.
Akugyo are monstrous fish usually encountered in the seas near Kibi Province (Okayama Prefecture). They're large in size and are known to capsize entire ships, before feasting upon the drowning sailors.[1][2] Some Akugyo breathe fire, while others resemble gigantic versions of Ningyo with gold and silver scales. The variety which appear as colossal mermaids usually have a pair of two white oni-like horns sprouting from their head. Fishermen fear them because their boats can easily become lodged between the fins of an Akugyo, allowing the yōkai to eat the crew.
