Tea Ceremony is a way of entertaining guests by preparing powdered green tea according to an established order.

Possibly the ceremony was first exploited as a means of setting feudal disputes. It is held in cha-shitsu, a small Japanese room, usually surrounded by a carefully designed garden. It is usually a thatched-roof structure with plain plaster walls, whose several openings, placed at different heights and filled with shoji (sliding panels of wooded lattice covered with paper), admit a soft, diffused light.

The room is usually about nine feet square or smaller. When the guests are summoned they enter through a small nijiriguchi or "kneeling-in" entrance, about 2 1/2 feet square. The fact that guests must crawl into the room is intended to inculcate humility in all who enter or thought to have served the purpose of preventing them from concealing a sword under their robes.
