1. "Kairo" (2001)
The early 2000s, the age of the dial-up internet. But "Kairo" takes our online anxieties to another level. College students start discovering this mysterious website that asks, "Do you want to meet a ghost?" Curiosity kills, right? They start experiencing weird events, like spectral figures in red tape appearing in their apartments. The figures touch them, and they disintegrate into ash.
The film paces these eerie events so you're constantly on edge, waiting for that modem to screech again.
2. "Dark Water" (2002)
Divorce can be messy, but throw in a haunted apartment, and you've got "Dark Water." Yoshimi moves into a rundown flat with her daughter, Ikuko. They notice water stains on the ceiling that grow larger each day. What's the deal, right? Well, they find out that the girl who lived upstairs mysteriously vanished. Yoshimi starts seeing this girl's ghost, who leaves a red bag similar to Ikuko's.
3. "Infection" (2004)
Set in a run-down hospital (why are they always run-down?), "Infection" revolves around a mysterious illness. One patient has this greenish ooze coming out of him. Ick. Despite the staff's best efforts to contain it, the gooey mess starts spreading like gossip. Staff members get infected, their flesh literally melting away. And would you believe it, they even start hallucinating!
The gore factor is top-notch, so consider yourself warned.
4. "Noroi: The Curse" (2005)
Another found footage masterpiece. A documentary filmmaker, Kobayashi, disappears while working on a project about a cursed entity called "Kagutaba." The film pieces together his collected footage. Interviews with witnesses, eerie ceremonies, and psychic phenomena all point to the awakening of this ancient evil. In one unnerving scene, a woman named Junko is shown in her home filled with dead pigeons.
5. "One Cut of the Dead" (2017)
This one starts like your average zombie flick — a director is shooting a low-budget horror film in an abandoned building rumored to have once been used for human experiments. Yep, you guessed it, real zombies show up.
But wait, there's a twist. After the initial 37-minute single take, the film switches gears. Without spoiling too much, let's just say you get to see the same events from a radically different perspective.
6. "Reincarnation" (2005)
In "Reincarnation," a film director decides to make a movie about a horrifying mass murder that happened in a hotel in the '70s. He casts a young actress, Nagisa, who starts having visions of the past killings. Even creepier? The actual hotel rooms start manifesting in her everyday life.
It's like a twisted Nolan's Inception but with horror; the lines between the film and reality blur so much, you're not sure which is which.
7. "Ju-on: White Ghost" (2009)
You've probably heard of "The Grudge," but let's talk about its lesser-known cousin, "Ju-on: White Ghost." The story revolves around a taxi driver who finds his sister dead in her apartment. From there, anyone connected to him starts experiencing hauntings. One girl gets a phone call from herself, predicting her death in three minutes. Tick-tock, right?
It unfolds as a series of vignettes showing how the curse affects different people.
8. "Marebito" (2004)
Masuoka, a freelance cameraman obsessed with capturing the essence of fear, stumbles upon a hidden, subterranean world beneath Tokyo. Down there, he finds a mysterious woman chained to a cave and decides to bring her to the surface. Bad move, man. She doesn't eat, doesn't speak, but has a peculiar thirst for human blood.
9. "Occult" (2009)
This one's a mockumentary but don't roll your eyes just yet.
After a stabbing spree during a solar eclipse leaves several people dead, the perpetrator goes full-on crazy, claiming he was chosen by higher beings. A journalist decides to investigate and discovers a secret society that believes the next evolution of mankind is... well, demonic. People start experiencing strange growths on their bodies, and footage shows orbs and mysterious figures.
10. "I Am a Hero" (2015)
"I Am a Hero" shows us a Japan overrun by an infection turning people into "ZQN" (read: zombies). Our protagonist is a manga artist with a shotgun who joins a group of survivors. The zombies here are unique; they retain some of their human memories and traits. Like, one zombie keeps running because he used to be a sprinter. It's a small detail, but adds a whole layer of creepiness.
