The Nosakamata are monsters within the Sanzu River that are more powerful than the Nanashi Company, resembling tremendous, skull-like, eyeless, crocodilian heads on two legs, and can shoot fireballs from their mouths. There are also some Nosakamata known as the Ōnosakamata, which are naturally born giant. Appearing in the Shinkenger movie are the Kusare Nosakamata, blue-skinned versions of the Nosakamata.
