What chanoyu means
Chanoyu, also called sado or chado, is the formalized practice of preparing and serving matcha to guests. The Urasenke, Omotesenke, and Mushakojisenke schools, all descended from Sen no Rikyu, set the procedures still taught today. A full chaji can run several hours and includes a meal, koicha, and usucha, while a shorter chakai centers on usucha alone.
