Kuni-zukuri
When Ōkuninushi-no-kami was at Miho-no-misaki in Izumo, a small god, wearing a wing of a moth, emerged from from beyond the sea on an Ame-no-kagami-no-fune. Ōkuninushi-no-kami asked his name but he got no answer, and no one knew his name. Then, Taniguku came and told him that Kuebiko, should know, so he visited Kuebiko. Kuebiko answered that the small god is Sukunabikona-no-kami, Kamimusubi-no-kami's child.
Ōkuninushi-no-kami visited Kamimusubi-no-kami to make certain. Kamimusubi-no-kami said that the small god certainly is his child, who got lost falling through his fingers. Kamimusubi-no-kami ordered Sukunabikona-no-kami to become brothers with the "Ashiharashikō-no-mikoto", and build the country together.
Ōkuninushi-no-kami and Sukunabikona-no-kami worked together and did the Kuni-zukuri of Ashihara-no-nakatsukuni. However, one day, Sukunabikona-no-kami left for Tokoyo-no-kuni, saying that his role has finished.
Still half way through the building of the country, Ōkuninushi-no-kami was at a loss. But when he was at the seashore, a god emerged from from beyond the sea illuminating the sea surface. The god said that if Ōkuninushi-no-kami would enshrine him, he would build the country together, if he won't the building will not go well. Ōkuninushi-no-kami asked how he should enshrine him. The god answered that he should enshrine him on top of the mountain in the east of Aokakiyama surrounding Yamato, so he enshrined the god in mount Mimoro. This is the god of mount Mimoro.
Thus, Ōkuninushi-no-kami finished the Kuni-zukuri of Ashihara-no-nakatsukuni.
