“The folklore — or legend — I want to share is a Korean ghost legend that I heard from my mom growing up. I heard it when our family first moved to the United States, when I was in second grade, around Halloween.

The story my mom told me takes place in her high school — an all-girls high school back in Korea. In the last stall of the school bathroom, a ghost pops up out of the toilet and asks if you want red or blue toilet paper. Unless you ignore the ghost and walk out, or say you don’t need any toilet paper, you’re not safe. If you choose either option — red or blue — the ghost kills you or drags you down into the toilet with it.

As for where my mom heard the story, she didn’t specify who she heard it from, but there’s a Korean word called quedam, which refers to well-known, typical ghost stories, especially ones set in schools. Korean high schools are large buildings, and they get very creepy at night with the lights off. My mom said a similar legend originated in Japan, among Japanese schoolgirls, and eventually found its way to Korea, where it became widely known across Korean high schools.

The ghost targets a specific group — students — and the story only occurs in a specific location: the last stall of a school bathroom. I don’t think the legend goes into the ghost’s origins. It’s not specific to one high school or one region. I think its purpose is simply to be a scary story that makes you think twice before using the bathroom late at night at school.

Korean high schools have a unique system where, unlike American high schools that end around 3 p.m., students are required to stay at school until late at night — sometimes until 10 p.m. — to study for college entrance exams. So the school gets dark, and that’s exactly the context where these kinds of ghost stories become very relevant.”

Context:

This text was collected from a sophomore civil engineering student at USC. He shared this legend in a recorded interview, recounting a story he heard from his mother when he was in second grade, shortly after his family immigrated to the United States. The legend centers on a bathroom ghost in the last stall of a Korean school, which offers victims a fatal choice between red and blue toilet paper. The informant learned through his mother that the legend likely originated in Japan among schoolgirls before diffusing into Korean school culture, where it became widely known under the broader category of quedam — a Korean term for traditional, well-known ghost stories. The legend is deeply tied to a specific institutional context: the Korean high school system’s requirement that students remain on campus studying until late at night, which creates the dark, isolated conditions that make the story feel plausible and threatening.

Analysis:

This text is a legend: it is set in the real world, targeting a specific location and population, and designed to feel believable rather than fantastical. Thus, Linda Degh’s point that legends function as debates about belief is useful here: the story doesn’t demand full belief, but it enacts enough doubt that a student alone in a dark school bathroom at 10 p.m. might hesitate and feel scared. This is also the legend’s social function; it governs behavior within the folk group of Korean students, creating informal rules around a vulnerable, isolated situation. Moreover, the story’s transnational diffusion from Japan to Korea is a clear example of oicotypification: the core structure travels across borders while adapting to fit the local institutional context of Korean school culture. The legend also does what ghostlore characteristically does: it attaches supernatural danger to a specific, mundane location, transforming an ordinary school bathroom into a site of folk belief. The story’s survival across generations and national borders speaks to its resonance with universal anxieties around isolation, darkness, and vulnerability.
