Seiza

Seiza (正座 or 正坐; せいざ SAY-(ee)-zah; lit.'proper sitting') is the formal, traditional way of sitting in Japan. It involves a specific positioning and posture in a kneeled position so as to convey respect, particularly toward elders. It developed among samurai during the Edo period and was later widely adopted by the public.

Seiza is associated with straw tatami flooring or zabuton pillows that allow for comfortable sitting, and it is commonly used in several Japanese practices, including Japanese martial arts and the Japanese tea ceremony. Sitting seiza-style is often difficult for people who are not accustomed to it or for the physically infirm, such as injured people and the elderly. Sitting seiza-style for long periods of time is associated with health problems, particularly those of the knees. Seiza may be compared to similar seated positions in other cultures, such as Indian Vajrasana.
