Chūgi with modern toilet paper in the background to give a size comparison

Chūgi (籌木?), sometimes called kusobera (lit. "shit spatula"), was a special type of stick used by the Japanese people from ancient times to clean the anus after defecation. The word chūgi is composed of the kanji for skewer (籌) and tree (木) which gives it the meaning of "wooden skewer". Chūgi were associated with their function as they have been found in excavations of toiletry remains. It is also believed that chūgi have been portrayed in paintings on scrolls from the end of the 12th century. One such painting depicts a child wearing high heeled geta in the process of defecating, bracing and holding a chūgi in his hand.
