Umashiashikabihikoji is a Japanese primordial deity.[1][2] He was the fourth one to come into existence.[2]
His name in Japanese is 宇摩志阿斯訶備比古遅神. He is also known as "Fine Budding Reed Lad". He is in the Kojiki and Nihongi. These are ancient Japanese texts. He is one of the earliest gods in Shinto.[2][1]
The Kojiki calls this deity Umashiashikabihikoji no kami. The Nihongi refers to it as Umashiashikabihikoji no mikoto.[1] He is one of the five Kotoamatsukami according to the Kojiki.[3] He is only cited in an "alternate writing" in the Nihon Shoki.[3]
Umashiashikabihikoji is linked to the creation of heaven and earth. The land was like floating oil at first. It moved like a jellyfish. A reed-like object appeared in this state. It turned into the kami Umashiashikabihikoji.[1]
Kamimusubi came before him, and he was succeeded by Amenotokotachi.[1]
He is a Hitorigami, or a singular divinity born early in the universe.[1]
He was not mentioned as an Oyagami or clan ancestor.[3]
