What is the difference between the Japanese tea ceremony and the Chinese tea ceremony?

The Chinese tea ceremony uses ordinary leaf tea but the Japanese tea ceremony uses finely-milled tea, called “Matcha”.

A tea pot is not used in the Japanese tea ceremony. To prepare a cup of matcha, a small amount of matcha is placed into the bowl, traditionally using a bamboo scoop called a chashaku, then a modicum of hot water is added.
Then it is whisked with a bamboo whisk known as a chasen. There must be no lumps left in the liquid and no ground tea should remain on the sides of the bowl. Because matcha can be bitter, it is traditionally served with a small wagashi and without added milk or sugar.

Chinese tea culture and the Japanese tea ceremony also differ in their goal. Chinese tea culture aims to make a delicious tea but the Japanese tea ceremony values spirituality. A Japanese tea ceremony host is taking care of not only the tea and sweets but the tea utensils, furniture, flowers, a hanging scroll, the tea house and the garden, as to whether they match the tea ceremony and the guests.
The essence of the Japanese tea ceremony is not the tea, it is hospitality.

We will offer cordial hospitality in our tea ceremony. Enjoy the tea ceremony to relieve the wearied mind from your busy days.
