The classical tea ceremony is one of Japan’s oldest traditions which are still kept and is practiced today. The first documented evidence of tea in Japan dates to the 9th century, when it was taken back by monks on their return from China. Since then, Japanese people drank tea in a ceremony that is unaltered until today:

The Japanese tea ceremony is a cultural activity involving the ceremonial preparation and presentation of matcha (抹茶), powdered green tea. The manner in which it is performed, or the art of its performance, is called Otemae. Buddhism was a primary influence in the development of the Japanese tea ceremony. 
Preparing tea in this ceremony means focusing into the predefined movements. The whole process is not about drinking tea, but is about aesthetics, preparing a bowl of tea as gracefully as possible. The host of the ceremony always considers the guests with every movement and gesture. Even the placement of the tea utensils is considered from the guests view point.

Tea gatherings are classified as an informal tea gathering Chakai (茶会) and a formal tea gathering Chaji (茶事), tea event. A Chakai is a relatively simple course of hospitality that includes confections, tea and perhaps a light meal. A Chaji is a much more formal gathering, usually including a full-course meal followed by confections and different kinds of tea. A Chaji can last up to four hours.

The tea ceremony takes place in a room designed and designated for tea. Usually this room is within the tea house, located away from the residence, in the garden.
The guests are shown into the waiting room first. While here, the guests choose one of their group to act as the main guest. The assistant of the host leads the guests, main guest directly behind, to a water sprinkled garden devoid of flowers. Here the guests rid themselves of the dust of the world. They then seat themselves on the waiting bench anticipating the approach of the host.

Just before receiving the guests, the host will fill up a stone basin which is set among low stones with fresh water. Taking a ladle of water purifies his hands and mouth then proceeds through the gate to welcome his guests with a bow. No words are spoken. The host and the assistant lead the main guest and the others (in that order) through the gate which symbolizes door between the coarse physical world and the spiritual world of tea.
Tea ceremony is an incredible experience to make if you happen to be in Japan. Is is a memory you won’t forget. If you’re in the Fukuoka area, there is the chance to participate in a tea ceremony in the Japanese garden in the Ōhoripark!
