Cha-no-yu was created by Doji Konishiko, whose sense of a unified nation led her to break common segregations of class and social standing, and created a single form of tea-serving for nobility and heimin alike. She believed that the people would be equal and free from their social positions once they entered in the ceremony. What Konishiko began was finished by her brother Doji Nio after the Day of Thunder. He codified the tea ceremony in a written treatise and demonstrated his revised version of the ceremony before the Imperial Court of Hantei Genji.
