Lit. dōan enclosure. Also called dōan zashiki 道安座敷 (dōan room). An enclosure used in a tea ceremony room, *chashitsu 茶室. A wall is built between the host's mat, *temae datami 点前畳, and the guests' mats, *kyaku datami 客畳. This structure is named after Sen Dōan 千道安 (1546-1606), the oldest son of Sen no Rikyū 千利休 (1502-91), founder of the Omotesenke 表千家 School of Tea Ceremony. One interpretation suggests that making the tea out of sight of the guests represented a spirit of modesty. The wall extends from the middle post, *nakabashira 中柱, to the wall in front of the host's entrance, *sadōguchi 茶道口. There is an opening with an arched top, *katōguchi 火灯口, and the wall above this opening is called katōkabe 火灯壁. The katōguchi is usually closed with a sliding door, *taikobari fusuma 太鼓張り襖, of tautly stretched paper covering both sides of a frame. An example of dōangakoi can be seen in the Tensetsudō 点雪堂 at Omotesenke, Kyoto. A tea ceremony room incorporating the dōangakoi is called *dōangakoi-no-seki 道安囲席.
