Washitsu (和室), meaning "Japanese-style room(s)", is a Japanese term used as an antonym for the term yōshitsu (洋室), meaning "Western-style room(s)." Another term for washitsu is nihonma (日本間), and the comparative other term for yōshitsu is yōma (洋間).
A distinguishing feature of washitsu (or nihonma) is their tatami flooring. Washitsu also usually have sliding doors (fusuma), rather than hinged doors between rooms. They may have shōji and, if the particular room is meant to serve as a reception room for guests, it may have a tokonoma (alcove for decorative items).
In the past, almost all Japanese rooms were washitsu, and Japanese people slept on futons laid on the tatami and sat directly on the tatami or on zabutons set on the tatami. Nowadays, many Japanese houses have only one washitsu, which is sometimes used for entertaining guests, and most rooms are Western-style. Many new construction Japanese apartments do not have washitsu at all, instead using linoleum or hardwood floors.
