Tsuginoma, also known as the Anteroom, is a one-mat area covered with flooring
planks. Although guests never see the area, it is still designed with the
same innovations of the other rooms. The west wall has no dividing lines.
The only aspects which cover the wall, are the window and the paper covering
the bottom third of the wall. Although the original had another window
and a middle post, they no longer exist. The Tsuginoma has one of the two
shelves in Taian. In the corner of the room, there is a plank of Paulownia
wood held by one thin extending bamboo pole. The interesting innovations
in the Tsuginoma prove that Rikyu extended his wabicha design to areas
other than the tearoom.
