Tea is enjoyed all around the world. A host of a tea ceremony in Japan, may extensively prepare to ensure the hand movements are flawless. It is also common for the guests of a tea ceremony to wait in another room called machiai.
In Japan, the tea ceremony is often held in temples, led by Buddhist priests trained in the art of chado, “the way of tea”, and involves the use of matcha, a powdered green tea. In the predominantly Buddhist country of Tibet, tea is traditionally prepared in monasteries with the addition of butter made from yak’s milk.
