The aim and purpose of this paper is to show the differences and similarities between Japanese and Norse mythology, in order to get a better insight into the ways people were thinking when science and technology did not rule, but things were imagined as they could possibly be. Back then, they relied on religion and magic to explain the world and everything around us. Kojiki is a ancient book where the mythological appearance of Japan is described, and which helped the Yamato emperors to unite Japan when there where many clans. They worshiped many kami or gods, which could be anything that existed, but only for the rare and important kami they build shrines. In Japanese mythology everything appears from chaos, than the gods of the Plain of Heaven which created the Japanese islands, humans, and many other kamis. The most important kami were Amaterasu, the goddess of Sun and the main ancestor of the imperial house, her brother Tsukiyomi, the god of Moon, and Susanowo the god of storms and the see. The mythology of the Norse originated around the Bronze Age, and the Norse were skilled sailors and later became famous Vikings. In Norse mythology, just like in Japanese mythology, everything arises from chaos, but than it continues completely on its own way. Out of the chaos appears the giant Ymir, the cow Audhumla and then Buri who is the ancestor of the gods. Buri's son Bor had three sons, Odin, Willi, and Ve, who killed Ymir and created nine worlds out of him, and later the first humans. Odin or Alfodr is considered the father of all humans and gods, and is a very ambitious god. His son, the god of lightning and storms Thor had the powerful weapon Mjollnir for which he was famous, and he had many adventures with Loki and was often in trouble because of him. Loki is a god of fire and a trickster god, and was very cunning and clever. His children were: Fenrir the wolf, Jormungand the snake, and the daughter Hell, who all would help him cause the end of the world or Ragnarok. When Ragnarok begins he will attack all the gods with his monstrous children and an army of the underworld. When comparing both mythologies, many similarities and differences can be seen, as well as the influence of mythology on the culture. The similarity of these mythologies can be seen in the fact that they have the same beginning, in other words some chaos, which could be said, that they did not have a clear picture of what could be the source of everything, and because of that they explained it by disorganization or chaos. Furthermore, both the Japanese and the Nordic major gods are quite humanized, and it could be concluded that they considered humans as the pinnacle of divine creation. However, the difference is that the Japanese people considered themselves to be the pinnacle of creation, because everything is focused only on Japan. One of the main differences is that most of the Japanese gods are on Earth, when the Nordic gods have their own separate, "unreachable" kingdom for ordinary people. This shows a strict separation between the human and the divine.
