Stories of the Japanese People 01394 [Ainu Mythology] The Appearance of Ainu Rakur

First, let us look at the Ainu before the expansion of Japan and the Yuan Dynasty.
Because the Ainu people did not have a writing system, they passed down epic poems featuring heroes, known as 'Yukara,' through oral tradition. Although these 'Yukara' consist of a considerable volume, the main themes are:
・The exploits of a hero god named Ainu Rakur (also known as Oina Kamuy)
・The exploits of a human hero named Poyaumpe
I would like to explain these two points in detail.
The story of Yukara begins with the young protagonist, Ainu Rakur, being raised by his mother deep in the mountains.
One day, Ainu Rakur is told by his mother to go catch a deer, so he heads up the river. There, a cicada and a crow fly down and instantly transform into two young girls. As Ainu Rakur hides behind a rock and listens to the two girls talking, they are singing things like:
'Searching through the country, burning villages, searching the shelves, holding the large bowl, the chest, and the pot, let us make a hood for Ainu Rakur.'
'Searching through the country, burning villages, searching the shelves, holding the large bowl, the chest, and the pot, let us make a headband for Ainu Rakur.'
Hearing this mysterious pillow word, 'searching through the country, burning villages, searching the shelves,' Ainu Rakur returned home, angry, convinced it must be an insult.
After returning home, his mother puts on the formal attire of a shaman and begins to tell him of his origins.
'At first, the land was desolate, with neither trees nor grass growing. The goddess of the Chikisani (alder tree) was sent there from heaven. Among the brother gods who ruled the heavens, the younger brother came to love the Chikisani deeply. For this, he was blamed and forced into battle, and the younger brother had to fight every day without rest. The younger brother had no choice but to enter other people's houses without permission, search their shelves, and eat using their large bowls; furthermore, finding even that to be a bother, he would hold the pot to his chest to eat his rice. Moreover, because of the fighting, villages were burned, and the younger brother was given nicknames such as "searching through the country, burning villages, searching the shelves" and "holding the large bowl, the chest, and the pot." If I must hide nothing, you are the one born between that younger brother and the Chikisani.'
To his surprise, Ainu Rakur was the son of a god who ruled the heavens. It was also revealed that the one he thought was his mother was the 'Sun Goddess,' who had been entrusted by the Chikisani to raise Ainu Rakur.
In this way, Ainu mythology does not begin with the gods creating the world, but rather starts from the scene where Ainu Rakur learns of his own origins. By intentionally reversing the chronological order, they enhance the narrative quality, which is quite interesting.
