Chado, or the Way of Tea, is one of the most ancient and revered arts of Japan, and is at the very heart of Japan House. There are many different variations of this art form. Traditionally, guests sit in the seiza posture (kneeling with the tops of the feet flat on the floor and sitting on the soles). But there is a variety of tea ceremony in which one sits on a chair while drinking the tea. This is called the Ryūrei style.
