Hyottoko and Okame
Hyottoko (火男) is a comical Japanese character, portrayed through the use of a mask. His mouth is puckered and skewed to one side. He is often wearing a scarf around his head (usually white with blue dots). The origin of the name comes from "fire" (火 hi) and "man" (男 otoko), because the character is blowing fire with a bamboo pipe, hence the shape of the mouth.
Okame is like the female version of Hyottoko, and their masks usually appear together. Like her male counterpart, Okame is a positive figure and sometimes thought to bring good luck. She is portrayed as a woman with a large, oval-shaped head and smiling eyes. She is also known as otafuku.
