Imaginary drawing of Kajipogo created by merging multiple images
Kajipogo is an aquatic cryptid reported from the Kaji River, Shibata City, Niigata Prefecture, Japan.
One evening in 2014-2015, an elementary school student was crossing the Sakura Ohashi Bridge over the Kaji River in his grandmother's car.
While crossing the bridge, he saw a two-meter black fin-like object, resembling the dorsal fin of a killer whale, protruding from the water on its downstream side.
An eyewitness, an elementary school student, imagined it to be an eel-like creature with a huge dorsal fin and named it Kajipogo, after the Kaji River and Ogopogo.
Kaji river
The site is shallow and seven kilometers from the ocean, making it impossible for large creatures to enter from the sea.
There is no landing place near the Sakura Ohashi Bridge, and boats rarely pass by, so it is hard to imagine that he mistook the boat for a dorsal fin.
Near the Sakura Ohashi Bridge, round bale is sometimes placed along the river at certain times of the year; it is possible that the cover of the round bale was peeled off by wind or other factors and covered the trees sticking out of the river, giving the appearance of a dorsal fin.
