Sōtai is a muscular movement therapy developed by a Japanese doctor from Sendai, Japan; Keizo Hashimoto (1897–1993).
The term So-tai (操体) is the opposite of the Japanese word for exercise: Tai-so (体操). Dr. Hashimoto argued that Sōtai provides an antidote to the forceful and regimented exercises of Japan. His philosophy was that anyone could practice Sōtai easily to restore balance and health.
