Shoin (書院^?) means "drawing room" and "study" in Japanese domestic architecture.

 The term originally meant a study and a place for lectures on the sūtra within a temple, but later it came to mean just a drawing room or study.

 From this room takes its name the shoin-zukuri style.

In a shoin-zukuri building, the shoin is the zashiki, a tatami-room dedicated to the reception of guests.
