<bot>: Of course, I can help you look up information on the history of Japanese tea ceremonies. The traditional tea ceremony, called Chanoyu or Sado, has its roots in the 8th-century practice of Zen Buddhist monks. By the 16th century, it had become a popular event among Japan’s upper classes. Today, the tea ceremony is still a popular activity. It typically involves the host of the ceremony preparing matcha green tea for their guest. Accompanied by a traditional sweet, the tea is presented in a utensil-rich setting by a higher ranking guest or the host. The ceremony is a leisurely affair and includes reciting poems or chanting sutras as part of its ritual.
