Oshiroi

Oshiroi (白粉) is a powder foundation traditionally used by kabuki actors, geisha and their apprentices. The word is written with kanji meaning "white powder", and is pronounced as the word for white (shiroi) with the honorific prefix o-.

When worn by geisha and maiko, oshiroi is notable for only partially covering the nape of the neck, as an uncovered nape was traditionally considered erotic in Japanese culture.
