Sports and physical power
Ame-no-tajikarao (アメノタヂカラオ) is a Japanese deity (kami) who appears in Japanese mythology. Ame-no-tajikarao is written as 天手力男神 in Kojiki, and 天手力雄神 in Nihon Shoki. Tajikarao's name means heaven hand power.
Another name is Oosugutama-no-mikoto or Takuzutama-no-mikoto (多久豆魂命), as Ama-no-Iwatowake-no-kami (天石門別神) other names is Ookuzutama-no-mikoto (大国栖玉命) and Tachikarao-mikoto (大刀辛雄命).
At the event of Amano-Iwato (天岩戸, literally "heavenly rock cave"), Ame-no-tajikarao waited at the caves' door to pull out (in the Nihon Shoki and the Kogo Shūi, 'to pull open') Amaterasu (天照) from the cave, and thus return light to the world.
During the Tenson kōrin, Amaterasu had Omoikane, Ame-no-tajikarao, and Ama-no-iwato-wake-no-kami accompany the Imperial Regalia of Japan when it went to the Ise province to be enshrined at Ise Grand Shrine.
In the genealogy of Mochizuki (望月氏) clan, he is the grandson of deity Kamimusubi (神産巣日) and the ancestor of a clan of the ancient kingdom of Ki-no-kuni-miyatsuko (紀国造), which is modern-day Wakayama Prefecture, which in the Shinsen Shōjiroku (新撰姓氏録, "New Selection and Record of Hereditary Titles and Family Names").
However, in another genealogical text, Ame-no-Tajikarao appears to be the child of Ame-Yagokoro-Omoikane-no-mikoto (天八意思兼命 - another name of the deity Omoikane (思兼 or 思金), which is the honored distant ancestor of the Achinohōri clan. Although in relation to this clan, inscribed in another text, the child of the deity Omoikane, Ame-no-Uwaharu-no-mikoto (天表春命), the name of Ame-no-Tajikarao is nowhere to be seen in the genealogy tree.
His own Shinto priests think he was originally a protector of agriculture (maybe because he brought back sun light to the world, or maybe because peasants need fitness to work in the fields). Strangely, this god is often in association with Sugawara no Michizane, as the god Tenjin.
The name Ame-no-tajikarao carries the connotation of a male god with extreme and surmounting physical brute strength. The Japanese company, Tachikara, which specializes in sports equipment, is named after the god, because he is "known historically as the 'god of power' in Japanese folklore."
Ame-no-tajikaro is believed to be a god of sports and physical power, and is enshrined at shrines associated:
At the Togakushi Shrine there's a legend that says that the cave door that Ame-no-tajikarao threw away landed on Togakushi mountain (戸隠山) in Shinano Province (信濃国).
