15 Best Horror Anime That Will Actually Keep You Up at Night

Though anime may not have a strong track record when it comes to horror, several series in the medium can still give you your worst nightmares through their thematic representation of the genre. You may not find the kind of conventional scares often seen in Western horror movies. Instead, anime has given the genre a new perspective that often defies traditional horror storytelling. Yet, they are equally capable of keeping you awake at night.

So, after going through almost every anime that falls under this category, we’ve carefully picked the 15 best horror anime that every horror fan must watch. So, without further ado, let’s dive right in.

1. Perfect Blue Blurs the Line Between Horror and Reality

The only movie we have on the list, but perhaps the most deserving. Perfect Blue essentially tells the story of a former idol who aspires to become an actress. However, she is constantly haunted by a stalker, which gets her tangled in several murder cases. Things escalate so badly that she even finds it hard to distinguish reality from hallucination. Its paranoia aspect is genuinely chilling, and even without conventional horror elements, it will be one of your scariest watches.

Where to Watch (USA): HBO Max

2. Higurashi: When They Cry Is Too Violent With Its Narrative

The amount of graphic violence shown in Higurashi: When They Cry is not for the faint of heart. But it’s not just all about gore. The plot is also psychologically dense, with themes that can genuinely terrify you. Especially as it turns into a murder mystery following a series of disappearances of children in a secluded countryside setting. Higurashi even gives off an unexplainable sense of paranoia as friendships eventually spiral into madness. Thus, for good reasons, it is often claimed to be one of the best horror anime.

3. Another Captures the True Horror of Inevitable Deaths

The equivalent of Final Destination, Another offers an unfathomably hard-to-watch storyline where the death of each character is almost guaranteed because of a curse. However, you won’t know how they will die until it happens right before your eyes. And we kid you not, some of the deaths in the anime are so painfully brutal that simply thinking about them may take your sleep away. Though the ending of the series is a bit controversial, the scares will certainly keep you hooked throughout.

Where to Watch (USA): Crunchyroll

4. The Promised Neverland Offers Great Psychological Horror

What initially starts as a gripping escape thriller transforms into one of anime’s most haunting narratives by the end of Season 1. At first, The Promised Neverland introduced us to a group of kids who attempted to run away from their orphanage after learning that there was something wrong with the establishment’s way of doing things. But upon finally learning the truth, the series becomes almost impossible to watch. With the introduction of man-eating demons, it takes a full-on horror route.

Where to Watch (USA): Crunchyroll

5. Shiki Is a Genuinely Haunting Take on the Vampire Genre

When it comes to true horror vibes, Shiki might be the best that anime has to offer. Though it later turns out to be a vampire anime, the initial episodes build up the series’ horror atmosphere like no other. The secluded countryside village setting, the characters, the atmosphere, and even the soundtrack all masterfully contribute to building the suspense. Even some of the scenes in the anime are genuinely hard to watch, especially at night.

Where to Watch (USA): Shiki is not available for streaming in the United States

6. Corpse Party: Tortured Souls Offers the Most Graphic Gore

When it comes to nonstop, uncompromising gore, nothing can quite match Corpse Party: Tortured Souls‘s intensity. The narrative may not be its strongest aspect, but the gore will most definitely make you uncomfortable, to say the least. Each episode delivers some of the most gruesome torture scenes ever depicted in fiction. So, you may want to give it a try just for the sake of the experience. But we can’t guarantee that you will come out unscathed after actually finishing the whole thing.

Where to Watch (USA): Crunchyroll

7. Mononoke‘s Animation Pulls Off the Best Atmospheric Horror

Bending conventional tropes for atmospheric horror, Mononoke does something extremely unique. First of all, its narrative is packed with storylines that are simply bizarre (focusing on many Japanese folklores) and can easily become the source of absolute nightmares. But the best part about it is that the animation is extremely vibrant and colorful. There is almost no trace of the usual dark themes. But because of that, it offers a deeply unsettling and unique viewing experience.

Where to Watch (USA): Netflix

8. The Summer Hikaru Died Explores Cosmic Horror At Its Best

Some of the screenshots and trailers for the anime may make you think that it’s merely BL bait with minor horror elements, but that is definitely not the case. While those assumptions are not entirely wrong, the plot of The Summer Hikaru Died actually delivers one of the best horror storylines in anime. It essentially builds upon the central idea that someone you once loved may no longer be human. Would you still love them the same way? Also, the body horror in this anime is absolutely gruesome.

Where to Watch (USA): Netflix

9. Dark Gathering Actually Showcases Disturbing Ghost Entities

The classic Japanese horror vibes (ones that you may come across in Japanese live-action movies) are captured quite well in Dark Gathering. It does not present ghosts as mere supernatural obstacles, but as genuinely terrifying entities. The designs of some of the ghosts are straight-up nightmare fuel. And each encounter with them throughout the narrative is equally unsettling. Also, the plot goes deeper as we move forward with the anime, so it becomes an overall great watch.

Where to Watch (USA): Prime Video (rent)

10. Hell Girl‘s Horror Lies in Understanding Human Malice

Hell Girl technically isn’t a horror show, but its themes of exploring human malice through acts of evil scream horror. Though it essentially tells a gripping revenge story, the way each event unfolds and is portrayed in the anime makes it a horror masterclass. Even the atmosphere in the series is scarier than that of some of the other entries on this list. Furthermore, the series’ psychological aspect makes it way more terrifying than the plot may seem to be.

Where to Watch (USA): Prime Video

11. Kabaneri of the Iron Fortress Is the Best Zombie Horror

The desperate struggle to survive in a zombie apocalypse is hauntingly captured in Kabaneri of the Iron Fortress. In fact, many people compare it to Attack on Titan because of certain similar themes, and the Titans are basically like zombies in a sense. However, this anime elevates the horror aspects several times over, placing a much stronger emphasis on simply staying alive. Thus, it deserves a place on this list. It thrives both as a horror and action-seinen, which is its main selling point.

Where to Watch (USA): Netflix

12. Ajin Creates Suspense Through a Group of Immortal Beings

As the saying goes, immortality can be a curse in itself, and Ajin proves exactly that. It explores the complexities that may arise when one becomes immortal. Not only could they be subjected to inhumane experiments, but they might also become unbound by societal laws and do whatever they want. What makes this anime even scarier is, of course, the adaptation, which gives it top-notch horror vibes. The way the Ajins are portrayed in the series may give you your worst nightmares.

Where to Watch (USA): Netflix

13. Tokyo Ghoul Builds Upon Its Extreme Visceral Body Horror

Though the later seasons aren’t praised as highly as the first, Tokyo Ghoul conceptually delivers one of the most gripping plots in anime. The horror lies in the ghouls’ constant urge to consume human flesh. Despite being shown largely from the perspective of the ghouls, every human-ghoul interaction in the anime is filled with unsettling moments and body horror that can be extremely uncomfortable to watch. Also, the anime doesn’t hold back at all with its gruesome representations.

Where to Watch (USA): Crunchyroll

14. Yami Shibai Is an Anthology Series of Japan’s Darkest Tales

Yami Shibai captures the true essence of Japanese horror urban legends like no other anime. In fact, it does not do anything significantly unique with its storytelling, as each short episode recounts a particular horror incident presented as if it were a real-life event. As a result, every episode delivers a truly chilling narrative that may linger in your thoughts long after you finish watching it. The animation is simple, and the soundtrack is just right, but the payoff is incredibly rewarding.

Where to Watch (USA): Crunchyroll

15. Devilman: Crybaby Presents Apocalyptic Horror At Its Finest

The horror of Devilman: Crybaby extends far beyond simple graphic violence, and it is not even exactly about the demons either. Instead, it is the horror of losing one’s humanity and sense of self. The anime shows that as fear of something begins to spread throughout society, humanity itself may descend into chaos. And the result? A complete apocalypse, which can be far more terrifying than you could imagine. Thus, it definitely deserves a place on this list and also becomes a must-watch.

Where to Watch (USA): Netflix
