A room in a ryokan is usually a single large, undivided room floored with traditional tatami (rice-straw matting), with the only piece of furniture being a single low table. Doors are shoji (sliding screens), and decoration will usually be one or two simple ink brush drawings or scrolls. Seating in the room is on cushions, called zabuton, arranged around the low table. In the winter season, there may be a blanket around the table. You slip your feet under the blanket for the warmth of a kotatsu electrical heating unit.
