Amikiri (網切, Amikiri) is a yokai whose name means "net-cutter", it looks like a shrimp with a birds beak with two pinchers and hair. It flys around at night cutting mosquito nets and fisherman nets.
Amikiri are small, crustacean-like yokai which resemble shrimp or lobsters. They have a long body, a red, segmented shell, a bird-like beak, and two scissor-like claws on their forearms. They fly through the air as a fish swims in water, and are quite shy, rarely appearing before humans.
Amikiri don’t interact with humans very much, except for one particular activity which is the reason that they are called “net cutters.” For some strange reason, amikiri love to cut nets, whether it be a fishing net, a screen door or window, or a kaya — a Japanese hanging mosquito net. While they are not directly harmful, this mischief is not entirely benign either: the life of a fisherman is tough, and a fisherman whose nets have been shredded by an amikiri could find his livelihood ruined.
It’s unclear where amikiri come from, although they bear a very strong resemblance both in name and shape to an arthropod-like yokai called kamikiri. Stories about amikiri are rare, and their name and shape may actually be a pun; the word ami means net in Japanese, but it also is the name of a type of tiny shrimp.
A story from Yamagata prefecture tells of a fisherman who one day found that his fishing net had been shredded to the point of worthlessness. He suspected the work of an amikiri. The next day, he took special care to hide his nets at his home where they could not be found by any wandering yokai. That night, however, the amikiri snuck into his room while he slept and cut up the kaya covering his bed. The man woke up with his entire body covered in painful, itchy mosquito bites.
