It is written in an Edo period encyclopedia, that the te-naga people, with extraordinarily long arms, and
the ashi-naga people, with uncommonly long legs, lived in their own respective countries across the sea.
Despite having their own nations, they were often thought to pair up into sort of composite giants, with
the te-naga riding on the ashi-naga's shoulders, and go fishing and do other things together.

Te-naga and ashi-naga would also show up in Japan, often working together as a man-eating monster.
The te-naga-ashi-naga pair of Mt. Choukai was said to be so enormous it could sit on the mountain's
peak, capsize boats with its feet, and snatch up and devour the crew.

The appearance of these creatures could also be an omen of a change in the weather.
