Hikimayu
was the practice of removing the natural eyebrows and painting smudge-like eyebrows on the forehead in pre-modern Japan.
Hiki means "pull" and mayu means "eyebrows". Aristocratic women used to pluck or shave their eyebrows and paint new ones using a powdered ink called haizumi, which was made of soot from sesame or rape-seed oils.
