The {{nihongo|'''Land of the Back Door'''|後戸の国|Ushirodo no Kuni}} is an extradimensional location ruled by [[Okina Matara]] which first appeared in ''[[Hidden Star in Four Seasons]]''.

The area is a seemingly endless plane of floating doors which lead to different locations in [[Gensokyo]]. Not much is known about the place other than that it seems to have been created by Okina.
