The direction opposite the kimon, the southwest (hitsuji-saru; between the Ram (eighth sign of Chinese zodiac which means south-southwest) and the Monkey (ninth sign of Chinese zodiac which means west-southwest)), is called Urakimon (the back demons' gate), and people have an aversion for this direction as well.
鬼門とは反対の、南西（坤ひつじさる）の方角を裏鬼門と言い、この方角も忌み嫌われる。
