In Japanese mythology, Ama-tsu-Mikaboshi (ja:天津甕星, "August Star of Heaven"), also called Ame-no-Kagaseo (ja:天香香背男, "Brilliant Male"), and later Ama-no-Minaka-nushi ("Divine Lord of the middle heavens") was originally a Shinto god of the Pole Star and the primordial chaos. Under Chinese Buddhist influence, the god was identified with "Myo-Ken" (Sudarshana), as either Venus or the pole star, before being combined with the god of all stars, Ama-no-Minaka-Nushi.
He is mentioned in passing in the Nihon Shoki as an opponent of Takemikazuchi-no-kami during the latter's conquest of the land of Izumo, and is sometimes identified with the figure of Takeminakata in the Kojiki.

...願染みの度合い、等の様々な観点から判定して、この金星が、やはり、天津甕星(天香 香背男)として、一番相応しいのではないかと考える。 - ...so judging from degree of familiarity, and various other perspectives, this Venus indeed looks to be the most appropriate match for Ama tsu Mikaboshi (Ame no Kagaseo).
