A word of warning… most of these books are really unsettling, but also pretty difficult to get a hold of. Only those with strong hearts should google each of these horror manga to read more about them and find translations of the stories online.

1. The Enigma of Amigara Fault by Junji Ito

Thousands of human-sized holes appear in the side of a mountain following an earthquake. It doesn’t take long for people to find holes that match them perfectly, and everyone who finds their hole becomes obsessed crawling in and being swallowed up by the mountain. What happens next will give you nightmares for weeks.

2. Homunculus by Hideo Yamamoto

A man who is out of a job and a home gets an offer he can’t refuse. In order to get back on his feet, he agrees to undergo an experimental trepanning procedure. After he has a hole drilled in his skull, he starts to experience the world differently and see people for who they really are.

3. Uzumaki by Junji Ito

Ugh. So upsetting. A series of stories about a town and its inhabitants who become enthralled by spirals. Spirals begin appearing everywhere, and the town devolves into chaos as its citizens become obsessed with transforming themselves and their environment to usher in the supernatural force behind these spirals.

4. Kouishou Radio by Nakayama Masaaki

A series of ghost stories all relating to spirits that manifest themselves via the medium of human hair, for the most part. Yeah, it’s as weird as it sounds, but somehow also totally haunting, and the imagery will stick with you a long time after you’re finished reading.

5. Dragon Head by Mochizuki Minetaro

A train full of students derails in a tunnel during an earthquake. The few young survivors need to try to maintain their sanity as they find a way out, away from the wrecked train filled with the rotting remains of their classmates. But the world they’re trying to make their way back out to is not the same one they left behind.

6. Human Chair by Edogawa Ranpo and Junji Ito

Exactly what it sounds like. A short story about a chair that holds a dark secret. (It’s a person. It holds a person.)

7. Gyo by Junji Ito

Fish, sharks, whales and other sea-dwelling creatures grow spider legs and begin invading the land, which is somehow THE LEAST STRANGE AND REPULSIVE THING TO HAPPEN IN THIS STORY.

8. Jisatsu Circle by Furuya Usamaru

This series starts with 54 young women gleefully jumping in front of a train together and committing suicide… except for the one girl who manages to survive the incident unscathed, who then becomes obsessed with death and finishing what she started at the beginning of the series.

9. Emerging by Hokazono Masaya

A business man comes down with a mysterious illness and erupts in an explosion of blood in the middle of a busy Tokyo intersection, coating everyone nearby in blood and viscera. Before long, the illness begins to spreading faster than everyone in the sanitized city can handle.

10. Fasting by Umezu Kazuo and Hisashi Eguchi

A truly upsetting short story of a young girl who develops an eating disorder. As the pounds fall off, she gains the attention of the boy she’s always had a crush on… as well as an uncontrollable hunger.

11. Dokumushi Kozou by Hideshi Hino

Dokumushi Kozou (also known as “The Bug Boy” outside of Japan) is a little like Kafka’s The Metamorphosis, if The Metamorphosis was a gore-filled nightmare. A young boy who doesn’t seem to fit in gets bit by a mysterious insect. Instead of gaining super powers like Spider-Man, he transforms into a grotesque monster, reviled by his family and neighbors.

12. Heads by Keigo Higashino and Motoro Mase

After getting shot in the head, Naruse Jun'ichi receives a brain transplant, and makes a miraculous recovery. But it isn’t too long before he finds himself repulsed by his girlfriend’s freckles, which he once loved. Then his whole life begins to change as the donor brain starts to take control.

13. Fuan no Tane by Masaaki Nakayama

A series of short ghost stories full of the sort of blank-faced, wide-eyed spirits you might expect if you’re familiar with Japanese horror films like Ju-On. The stories in this series are sometimes a little more light and sometimes a little more humorous than other horror manga on this list, but will still fill you with dread.
