Kotodama(言霊) is a Japanese word, the mystical force inherent in language

The term: kotodama itself, translates at a simplistic level, as: "Word Spirit" and refers to a Spiritual state or feeling induced by beautiful 'word-sounds' when correctly intoned. (More fully, kotodama encompasses the notion that good can be brought about as a result of correctly-intoned beautiful 'word-sounds' and evil brought about by ugly 'word-sounds' - or by beautiful 'word-sounds' incorrectly-pronounced.)

Kotodama is inseparably bound up with the concept of kotomuke ['soothing speech that brings peace'] and kotoage [the practice of speaking boldly in the presence of the Kami (numinous beings), seeking to invoke the magical power of words]
