Kamae (構え) is the Japanese word for posture (differing from tachi, the word for 'stance'). Kamae refers to the posture of the whole person, both physical (身構え, migamae) and mental (心構え, kokorogamae). In both migamae and kokorogamae, kamae refers to one's readiness and preparedness for future action.
Kamae in aikidō varies considerably between styles.
Kamae in yōshinkan aikidō is quite distinct compared with Aikikai styles. To step into yōshinkan kamae, begin from shizentai (natural posture) and take a large step forwards with one foot, sliding the rear foot forwards a small amount following it, in order to reach a position where 60% of the weight is on the front foot, and 40% on the back foot. The hand of the front foot should be held out directly in front of the sternum with a slight bend in the elbow. The second hand should be held in front of the hips. The fingers of each hand should be spread and the back leg held straight with the sole of the foot touching the floor.
