Akkorokamui is a legendary creature from the folklore of the Ainu people, an indigenous group of people from northern Japan and Russia. According to Ainu mythology, Akkorokamui is a massive octopus-like creature that lives in the sea and is said to be about 120 meters long. Its name roughly translates to "the deity that shakes the land."

Akkorokamui is said to have a red body and long, flowing tentacles that it uses to drag ships and fishermen down to the depths of the sea. However, some stories describe it as a gentle creature that helps lost fishermen find their way back to shore.

There are many stories and legends associated with Akkorokamui, and its depiction varies depending on the region and the storyteller. Some tales describe it as a malevolent creature that causes storms and wreaks havoc on ships and coastal communities, while others depict it as a benign guardian of the sea.

In recent years, Akkorokamui has become a popular subject in Japanese pop culture, appearing in manga, anime, and video games. Some modern depictions of Akkorokamui portray it as a cute, friendly creature, while others retain its more menacing characteristics.

It's important to note that Akkorokamui is a mythical creature and there is no scientific evidence to support its existence.
