Overview

Wielded by the male creator-god Izanagi, this blade is used to cut up the infant Fire God Kagu-Tsuchi after his birth burns Izanami to death. It cuts the Fire God into multiple pieces, creating eight volcano-gods. When blood drips from the blade afterwards, the Sea God Watatsumi and the Rain God Kuraokami are formed.
The name of the ten-fist sword wielded by Izanagi is given postscripturally as, otherwise known as Itsu-no-ohabari.
In the Kojiki, the heavenly deities Amaterasu and Takamusubi decreed that either Takemikazuchi or his father must be sent down for the conquest. Itsu-no-ohabari here has the mind and speech of a sentient god, and he volunteered his son Takemikazuchi for the subjugation campaign. Takemikazuchi was accompanied by "Deity Heavenly-Bird-Boat".
