It states that Ishikoridome formed a Sun Spear made out of copper from Mount Kagu to help get Amaterasu out of the cave as well as Heavenly Bellows out of Stag Hide. It then goes on to say that the Deity which she fashioned by this means was called Hinomahe and lives in Kii Province.1
(So I am unsure due to the reading whether she is infact these Heavenly Bellows, or a seperate deity entirely).
