Sado Ceremony

The Japanese tea ceremony is a traditional ritual based on Taoism (Daoism) and influenced by Zen Buddhism in which powdered green tea, or matcha, is ceremonially prepared by a skilled practitioner and served to a small group of guests in a tranquil setting.
The pronunciation sadō is preferred by some schools, including Omotesenke and the Mushanokōjisenke,while the pronunciation chadō is preferred by others, including Urasenke. Cha-no-yu (literally "hot water for tea") usually refers to either a single ceremony or ritual, while cha-ji or chakai (literally "tea meeting") refers to a full tea ceremony with kaiseki (a light meal), usucha (thin tea) and koicha (thick tea), lasting approximately four hours.
Since a tea practitioner must be familiar with the production and types of tea, with kimono, calligraphy, flower arranging, ceramics, incense and a wide range of other disciplines and traditional arts in addition to his or her school's tea practices, the study of the tea ceremony takes many years and often lasts a lifetime. Even to participate as a guest in a formal tea ceremony requires knowledge of the prescribed gestures and phrases, the proper way to take tea and sweets, and general deportment in the tea room.
