  • tentou 天道, or tendou 天道, literally "Heaven Path," refers to the path travelled by the heavenly bodies, i.e. the stars, a.k.a. the gods, deities, etc. In Japanese, the "Sun," taiyou 太陽, may also be called otentousama お天道さま. The word tentou also refers to heavenly God and "Supreme Deity" Shàngdì 上帝.[1][2]
