who created the island of japan by stirring the water with a spear
Kuniumi The elder gods delegated the youngest couple Izanagi and Izanami to carry out their venerable mandate: to reach down from heaven and give solid form to the earth. This they did with the use of a precious stone-covered spear named Ame-no-nuboko (天沼矛, "heavenly jewelled spear"), given to them by the elders. Standing over the Ame-no-ukihashi (天浮橋, "floating bridge of heaven"), they churned the chaotic mass with the spear. When drops of salty water fell from the tip, they formed into the first island, Onogoroshima. In forming this island, both gods came down from heaven, and spontaneously built a central support column [2] called the Ame-no-mihashira (天御柱, "heavenly pillar") which upheld the "hall measuring eight fathoms" that the gods caused to appear afterwards.[1][3][4][5]
