Junji Ito’s The Thing That Drifted Ashore is a short, simple, but also deeply disturbing story. It’s less about what happens, and more about what it suggests.
While the most memorable part is its visual centerpiece, the sea creature washed ashore, the true horror of the tale goes much deeper. It’s about survival, identity and horrors of the deep sea.
Plot Overview – A Monstrous Discovery
The story opens after a massive sea creature washes ashore. Yet something’s different. It’s not a whale or other known marine animal, but something far different and alien. Soon enough a crowd of people gathers. Some are there out of curiosity, others to identify the unknown creature. Amongst them is a young man, terrified of sea creatures, and a young woman named Mie, who lost her fiancé in a shipwreck seven years ago.
While the scientists examine the creature, they notice something strange. Certain parts of the creature’s skin are translucent, and behind it, human faces can be seen.
At first, it’s presumed they are the creature’s victims, but it’s soon discovered that they are still alive. Yet when the creature’s body is cut open, there’s an even more horrifying revelation: the people inside are still alive. They are the shipwrecked who survived by becoming parasites. When they finally break free, however, they are no longer sane, but entirely broken.

What Makes The Thing That Drifted Ashore So Good?
It’s one of Ito’s most minimalistic stories, but also one of his most haunting. The narrative is straightforward, yet every detail builds towards its final, horrifying revelation.
The creature itself is a masterpiece of grotesque design. It’s gigantic, serpentine, and utterly alien. Its head comprises nothing but tumorous growth and tendrils, making it look more like a deranged nightmare than any known species. The scientists speculate that it’s a prehistoric lifeform, something much older than man. All that’s clear, however, is just how little we know about the depths of the ocean.
The horror deepens at the idea of people surviving as parasites, adapting and transforming while inside an alien organism. They survived, but at what cost?
The story’s most haunting element, comes from the young man who fears sea creatures. His fear is validated in the worst possible way. If the creature’s skin is translucent, and the people survived behind it for seven years, then what exactly did they see down there? Was it really living on as parasites that drove them mad, or was it something else?
This gives us the story’s final implication. While the creature that drifted ashore is nightmarish, there might be things out there that are much, much more horrifying.

Deeper Themes – Survival, Transformation, and the Abyss
The core question of the story is what it means to live inside another being. The thought is horrifying. For the people inside this story, survival comes at the cost of transformation and losing one’s humanity. As a result, their minds are broken, their identities warped, and they ultimately end up as insane.
The story also toys with our fear of the unknown, specifically the depths of the ocean. First, by the appearance of the grotesque creature that washed ashore. Then, by the idea of humans being forced to become parasites. And lastly, the implication that there are much worse horrors down in the depths of the ocean. This last part is the real horror of the story. We just don’t know, and that’s what makes the story’s terror linger.
The Thing That Washed Ashore also touches on the theme of voyeurism, spectacle and indifference. People flood to the beach to take in the view of the strange creature, almost as if it’s an attraction. None of them care about the creature itself, drawing sharp parallels to people gawking at beached whales. People don’t care about suffering, all they care about is spectacle.
Final Verdict – Quiet, Simple, and Cosmic
The Thing That Drifted Ashore might be one of Ito’s simpler stories, but it’s still quite a piece. It’s not a story that relies on scares or gore, but on the final revelation and its implications.
It’s a story about the cost of survival, how it can warp people, and the horrors that lie below the surface.
