The Kojiki Creation Story recounts the exploits of Izanagi and Izanami, the deity and goddess who formed the Japanese islands from chaos, disorder, or formlessness. The creation myth continues with Izanami's death and Izanagi's pursuit of her to the Nether Regions, or the Underworld. There, he defeats Mibōtsu, a giant snake who had been coiled around the world in order to protect it. After this victory, they marry and have children together. Izanagi and Izanami are said to be the founders of many provinces, cities, and villages throughout Japan. They are also said to have created many other deities during their time on Earth. One such example is Susano'o, a fisherman who fought against Mibōtsu using his sword. He was able to defeat the monster after cutting off its head. Susano'o married another goddess after defeating Mibōtsu and they have twins who become the creators of islands too. Izanagi and Izanami are considered the ancestors of all Japanese people. They lived over 1000 years ago and are worshipped annually in many parts of Japan. A festival called "Izanami-no-Matsuri" (meaning "Festival for Izanagi and Izanami") is held every year in their honor. Izanagi and Izanami are described as being oneness with the gods.
