The philosophy of the Ryushin Shouchi Ryu entails cultivating the mind and conditioning the body through rigorous training for the purpose of improving the self rather than killing an enemy. This concept is more commonly known as fudoshin (immovable mind), which refers to a state of psychological and spiritual equanimity. Based on this reasoning, the name Ryushin Shouchi Ryu was selected by the founder, Kawabata Terutaka. Ryushin means “Mind or Heart of the Willow tree,” and invokes the image of a tree which does not lose its leaves even in winter; while Shouchi can be translated as “shining wisdom.” Together, these characters convey the sense of “establishing in the world an unmovable wisdom and everyday mind by means of a strong yet flexible body and spirit.”
