Amenominakanushi (天御中主 or 天之御中主神, "Heavenly Ancestral God of the Originating Heart of the Universe") is, according to the Shinto Kojiki, the first kami and the source of the universe. In Japanese mythology, Amenominakanushi is described as a "god who came into being alone" (hitorigami), the first of the zōka sanshin ("three kami of creation"), and one of the five kotoamatsukami ("distinguished heavenly gods").
Amenominakanushi had been considered a concept developed under the influence of Chinese thought, but now most scholars believe otherwise. With the flourishing of kokugaku the concept was studied by scholars. The theologian Hirata Atsutane identified Amenominakanushi as the spirit of the North Star, master of the seven stars of the Big Dipper. The god was emphasized by the Daikyōin[clarification needed] in the Meiji period, and worshipped by some Shinto sects. There are also scholars who believe that the Amenominakanushi concept was introduced in Japan sometime in the 7th or 8th century by the Nestorian or the Keikyo believers, underpinning its Christian origin.
The god manifests in a duality, a male and a female function, respectively Takamimusubi and Kamimusubi. In other mythical accounts the originating kami is called Umashiashikabihikoji ("God of the Ashi [Reed]") or Kuninotokotachi (the "God Founder of the Nation"), the latter used in the Nihon Shoki. Some sources identify these deities as the three Kamis called (three creator-Kami", a conceptualization that also reflect the so-called Kami of the threefold whirl (Amatsu uzu-uzushiyatsunagi) in Yamakage Shinto. These three gods, identified as a third of the three versions of the cosmogonic myths involving the kami, appeared in Takamanohara or the "domain of heaven" during the birth of the cosmos.
According to The Ancient Shinto Deity Ame-no-minaka-nushi-no-kami Seen in the Light of To-day, by Professor Katō Genchi, no authentic shrines dating from antiquity were dedicated to this deity, though two "recent" shrines, Wada-jinja (founded in A.D. 1659) and Okada-jinja, are allegedly dedicated to this god. Shinsen Shōjiroku mentioned only two families as descendant of Ame-no-Minaka-Nushi-no-Kami: Hattori-no-muraji and Miteshiro-no-Obito.
