Izumo expansion myth
He has a notable myth recorded in the Izumo Fudoki. The myth of Omitsuno is about making Izumo bigger. He saw Izumo as a small strip of land. He decided to add more land to it. He looked towards Silla for extra land.
Omitsuno used a special spade. It was shaped like a young girl's breast. He used it to cut land. It was like cutting through fish gills. He cut off pieces of land.
He attached these pieces to a three-strand rope. He pulled this land towards Izumo. He used a lot of strength. The land moved like a boat on a river. Omitsuno encouraged the land by shouting. He said, "Come on, land!"
The new land went from Kozu bay to Kizuki. This area is known for its pure spikes.
