The sound-based apartment horror film ”Inter-Floor Noise,” which has been the top-grossing Korean film for three consecutive weeks, will be released in Japan on October 10th! The teaser visual has also arrived.

Bangs, bangs, rattles... These are everyday sounds that we hear every day, but what if they were scary sounds that we couldn't identify the source of and that brought with them an unknown sense of fear?
The word "sōkansōon" is a Korean word that refers to the sounds of daily life (footsteps, voices, doors opening and closing, household appliances, etc.) that can be heard from the floors above and below in an apartment building.
The Korean horror film "Inter-Floor Noise," set in an old apartment complex where noises of unknown origin reverberate, was released in Korea in June 2025.
It has become an explosive hit, ranking first among Korean films for three consecutive weeks, and continues to attract huge audiences (as of July 30th).
The 57th Sitges Film Festival, a world-renowned film festival specializing in genre films,
Angel Sala Corbi, artistic director of the Korean Film Festival, called it "the best jump scare of the year," and others have also called it "a return of 'Dark Water'" and "a new masterpiece of Korean horror."
The film has received high praise. Director Kim Suzyn is a talented director who has won the Best Film Award in the "40,000 Blows" category at the Mise-en-scène Short Film Festival, and is known for her work on "The Wailing" and "Gongjia."
Park Yong-gi, the sound director of the TV series "The Potato Laboratory," has created a chilling sound that has never been heard before.
Lee Sun-Bin plays the difficult role of a man who, while searching for his missing sister, is confronted with the terror brought on by mysterious noises.
The role is played by Ryu Gyeong Su, who is currently gaining attention for her role in the hit TV series "Unknown Seoul" currently on Streaming on Netflix. The story of this film is interesting. One day, Seo Juyeon, who is hearing impaired,
She is informed that her younger sister, Juyeon, has suddenly disappeared. The two used to live together, but Juyeon started complaining about hearing noises, which Juyeon cannot hear even with her hearing aids.
When I entered the apartment in the apartment complex where Juhi lived, the ceiling was completely covered with soundproofing sheets. A neighbor came to visit me shortly after and said, "Please be quiet at night.
"Please, if you make any more noise, I'll tear your mouth to shreds," he threatened. However, after Ju-hee disappeared, there was no one in the room... Ju-yo decided to stay in the apartment complex until his sister was found.
Ng begins to hear strange sounds through his hearing aid, and soon begins to sense the presence of something... Could these be related to his sister's disappearance, or...?
The completed teaser visual shows the entire front door of the housing complex, with ominous writing in bold red letters.
"Please be quiet," the note read. There were also many other notes pasted on the wall, with messages such as "Your moaning is too loud," "Stop making footsteps," and "Do you think I'm joking? Why are you being so quiet?"
"Won't you listen to me?" and other such words are written on the wall, creating a gruesome scene that is hard to believe. However, the design is finished as a hint about the strange events that occurred in the room of the missing sister.
It is clear at a glance that the "scary sound" is having an unpleasant effect on the other residents. Is it a person, or...?
In the stills that were also sent, the main character, Seo Juyeon, opens the door a little and
The film captures a scene where one sneaks a peek into the underground corridor, creating an eerie atmosphere. Director Kim Suzyn testified that she had heard mysterious sounds and supernatural phenomena such as things falling down while writing the script and while filming.
We hope you will relive the "scary sound" experience that caused strange phenomena on the set in the cinema! Director: Kim Suzyn
