Japanese horror films, often referred to as J-horror, distinguish themselves from their Western counterparts through unique narrative styles and thematic tones. These films have captivated global audiences over the years, yet numerous gems remain relatively obscure. Characteristically, J-horror draws heavily from rich folklore, presenting antagonists in the form of supernatural entities such as ghosts. While they do incorporate violence and shocking moments, the true strength of many of these films resides in their ability to cultivate suspense and an unsettling ambiance.
This approach has contributed to the lasting appeal of J-horror, showcasing an alternative perspective on fear and tension. Notably, while several Japanese productions have been adapted for Western audiences—as evidenced by remakes like The Ring and Ju-On: The Grudge—there remains a treasure trove of lesser-known films that exemplify the best qualities of this genre. Audiences eager to delve deeper into Japanese cinema are in for a treat with these underrated films, including the likes of Evil Dead Trap and Infection.
10 Infection (2004)
A Mysterious Virus Spreads in a Hospital
Set within the confines of a dilapidated and understaffed hospital, Infection creates a haunting atmosphere that demands viewers suspend their disbelief. Despite its massive success in Japan—claiming the title of the second-highest-grossing film upon release, only behind I, Robot—it’s a title that has since faded from popular memory. The tension throughout the film is heightened by the unfolding chaos within Dr. Akiba’s hospital, leaving viewers captivated and anxious.
9 Gekijōban Zero (2014)
A Chilling Horror Movie Based on a Popular Video Game Series

While Gekijōban Zero, known internationally as Fatal Frame: The Movie, might resonate with fans of its associated video game franchise, the linkage is tenuous at best. The film revolves around the eerie disappearances of students at a Catholic all-girls school, primarily following Aya Tsukimori (Ayami Nakajō) and her comrade Michi Kazato (Aoi Morikawa) as they seek to unravel the mysteries plaguing their institution. Rather than relying on jump scares, this film builds an overwhelming sense of dread, ensuring viewers remain on edge.
8 Guzoo: The Thing Forsaken by God – Part I (1986)
A Slimy Creature Attacks Vacationing Girls

Despite its title, Kazuo Komizu’s Guzoo: The Thing Forsaken by God – Part I is a standalone film rather than a sequel. This brief 40-minute offering presents a bold and amusing monster horror story featuring a gelatinous creature that menaces a group of vacationing girls. Guzoo embraces its identity as a creature feature without striving for depth or complexity, which allows it to focus on delivering pure entertainment. Viewers appreciate this film not for its character development but for its impressive practical effects and unapologetic gore.
7 The Snake Girl and the Silver-Haired Witch (1968)
Strange Phenomena Occurs After a Young Girl Returns Home
During his tenure directing the beloved Gamera film series, Noriaki Yuasa also helmed The Snake Girl and the Silver-Haired Witch. This 1968 horror film, while not enjoying the same legacy as its kaiju counterparts, tells the story of Sayuri (Yachie Matsui), who returns home from orphanage life to a drastically transformed family dynamic. Critics often note the film’s reluctance to fully embrace its eccentric storyline, which, while intriguing, ultimately led to its underappreciation. Nonetheless, the effective costuming, makeup, and special effects establish a chilling backdrop for the occasional frights that punctuate the narrative.
6 Sweet Home (1989)
A Documentary Crew Tries to Survive in a Haunted House

In one of his early works, acclaimed filmmaker Kiyoshi Kurosawa establishes his horror narrative in Sweet Home. The plot follows a group of filmmakers who venture into the abandoned estate of artist Ichirō Mamiya, seeking to recover his lost artwork for their documentary. However, upon entry, they encounter the ghost of Mamiya’s deceased wife, plunging them into a perilous haunting. Although often overshadowed by the video game of the same name, which is credited as a pioneer of the survival horror genre, Sweet Home offers a unique angle on haunted house stories.
5 Wild Zero (1999)
Japanese Rock Trio Guitar Wolf Fight Off Zombies with a Superfan
A fun and quirky zombie film that has remained deceptively under the radar is Wild Zero, directed by Tetsuro Takeuchi. This comedy-horror features the real-life rock band Guitar Wolf, who, alongside a dedicated superfan (Masashi Endō), battles hordes of zombies during a chaotic outbreak. Despite receiving strong critical acclaim on platforms like Rotten Tomatoes, Wild Zero has yet to gain widespread recognition. Its blend of humor, relatability, and spirited characters still resonates with audiences seeking a lighthearted yet thrilling adventure.
4 Evil Dead Trap (1988)
A TV Crew Faces a Murderous Attacker

Blending elements from both giallo and slasher genres, Toshiharu Ikeda’s Evil Dead Trap delivers a visually striking and technically proficient viewing experience. The plot follows Nami (Miyuki Ono) and her TV crew as they unwittingly enter an abandoned location where a notorious snuff film was filmed. As the crew navigates their deadly surroundings, they face off against a merciless assailant determined to eliminate them one by one. The film is notorious for its graphic depictions of violence, ensuring it caters to enthusiasts of uncensored horror. Although the ending has generated mixed reactions, the film’s striking aesthetics and special effects have earned it a loyal following, in addition to inspiring two sequels.
3 Matango (1963)
Stranded Individuals on an Island Succumb to Mutagenic Mushrooms
Ishirō Honda, renowned for directing iconic kaiju films, also created the lesser-known Matango. This character-driven horror tale, loosely inspired by William Hope Hodgson’s story “The Voice in the Night,”unfolds on an isolated island where a group of castaways encounters mutagenic mushrooms. Rather than relying on typical monster encounters, Matango dives deep into the psychological and social dynamics at play as survival becomes increasingly fraught. The film’s exploration of class struggle adds another layer of depth, shining a light on darker themes that resonate with audiences.
2 Splatter: Naked Blood (1996)
An Experimental Drug Causes Destruction

Body horror stands as a thought-provoking subgenre, presenting disturbing transformations of flesh, often interwoven with deeper themes. While Japanese classic Tetsuo: The Iron Man is frequently highlighted, Splatter: Naked Blood deserves equal attention. This bizarre narrative follows scientist Eiji (Sadao Abe) as he seeks to create a drug meant to replace pain with pleasure. Unfortunately, the resultant addiction leads users down a treacherous path. Although rife with grotesque visuals, the film intertwines poignant commentary on societal issues, earning a place in the annals of J-horror.
1 Kuroneko (1968)
Two Vengeful Spirits Take Out Several Samurai
Kaneto Shindō’s Kuroneko, or The Black Cat, draws from Japan’s supernatural folklore, offering a haunting and feminine perspective on revenge. The film’s plot revolves around a mother and daughter duo who, after enduring violent deaths at the hands of samurai during wartime, return as vengeful spirits. Their quest for retribution leads to terrifying confrontations, showcased through striking cinematography. Although Kuroneko lacks the same recognition as Shindō’s Onibaba, it remains a quintessential piece of J-horror, embodying elements of suspense and folklore. The film also draws influence from traditional kabuki theater and forms part of a wave of “monster cat”films that emerged in the 1960s.
