It is a very unique room whose floor size is 3 tatami mats and has a temaeza (the seat for a host in a tea-ceremony room) made in the Daime-kamae style and, besides, can be made into a 4.5-tatami-mat room by taking out a door sill between the room and an adjoining 1.5-tatami-mat sayanoma (a narrow tatami-mat-floored passageway).
三畳敷であるが点前座の一畳を台目構えとし、また一畳半の鞘の間との敷居を外して四畳半の席にもすることのできる、大変珍しい席である。
