"According to legend, Akkorokamui was once a gigantic spider named Yaushikep who lived in the mountains nearby a village named Rebunge. One day, Yaushikep descended down to Rebunge and caused havoc. Fearing for their lives, the villagers prayed to the gods to save them. Their prayers were answered by the sea god Repun Kamuy, who pulled Yaushikep into Uchiura Bay. It is said that Yaushikep turned into a giant octopus who took over the bay as its god and since then, he has been known by the villagers as At-kor-kamuy or Akkorokamui." -- Akkorokamui WIKI
