The Chodaigamae (or decorative doors) is an architectural
element of Shoin Architecture that lost its functionality after its inception.
Originally the door
separated the raised floor section of a room to a secondary space, which
was often times either a storage room or a sleeping area. The doors were
fixtures marginalizing public and private spaces. Sometimes the spaces
behind the chodaigamae held bodyguards of the samurai so that they can
have easy access and escape from the space. However, as with the three
other display elements of the shoin, the functionality gave way to display
since they essentially became static panels. In the case of the chodaigamae,
the display was the architectural element itself which depending upon its
showiness demonstrated the wealth of the samurai.
