1. (the) tea ceremony
    Sado, or the way of tea, is commonly known as the Japanese tea ceremony. Powdered green tea was first used, mainly for ceremonial purposes, in Zen temples in the Kamakura era. Eventually it spread among the ruling classes and the affluent. In the late 16th century, Sen no Rikyu incorporated the Zen philosophy of impermanence into the tea ceremony and perfected the wabi-cha style, which valued simplicity. After his death, there was a division among his offspring, resulting in the establishment of three schools of tea ceremony: Omote Senke, Ura Senke, and Mushanokoji Senke. Many other styles have since branched off from them. The title of grand master (iemoto) is passed on hereditarily in each school. Many Japanese study the art of tea ceremony, which includes intricate protocol and manners, under the iemoto system. Licenses are available for various levels of practitioners.
