Halloween is not a Korean holiday by tradition, yet in the past two decades it has become one of the most visible imported celebrations in Seoul. What started as a small expat gathering in the bars of Itaewon has grown into a nationwide costume phenomenon driven by K-pop fan culture, K-drama nostalgia, and theme park marketing. Korean Halloween also carries a layer of grief, after the 2022 Itaewon crowd crush reshaped how the country thinks about urban safety and public celebration.
How Halloween Arrived in Korea
Halloween was virtually unknown in Korea before the mid-2000s. English teachers, U.S. military families, and exchange students began throwing private costume parties in expat-heavy neighborhoods, with Itaewon serving as the natural hub thanks to its proximity to the Yongsan Garrison and its international bars. By the late 2000s, Korean university students and young office workers started joining in, attracted by the novelty of dressing up.
From around 2010 onward, Halloween crossed firmly into the mainstream among Koreans in their 20s and 30s. Convenience stores stocked themed snacks, kindergartens taught the word jack-o-lantern, and shopping malls hung pumpkins next to autumn promotions. Today October 31 is widely recognized, even though it is not a public holiday and most older Koreans still see it as a foreign event.
Itaewon: The Original Halloween Capital, 1990s to 2022
For nearly three decades, Itaewon was the undisputed center of Korean Halloween. The neighborhood's mix of international restaurants, foreign-friendly clubs, and the famous World Food Culture Street made it feel closer to a Western celebration than anywhere else in the country. From the 1990s, bars along the main Itaewon-ro and the narrow alleys behind the Hamilton Hotel hosted themed parties that drew foreigners and Koreans together.
By the mid-2010s, Halloween weekend in Itaewon had become the single busiest night of the year for many local businesses. Costume contests, club crawls, and street parades filled the streets, and the area's identity as a global village neighborhood made it the natural backdrop for the holiday.
The 2022 Itaewon Tragedy and Korea's Response
On October 29, 2022, a crowd crush in a narrow downhill alley behind the Hamilton Hotel killed 159 people, most of them young Koreans and foreign students in their teens and twenties. The disaster happened on the Saturday before Halloween, when an estimated 100,000 people had gathered in Itaewon. It became one of the deadliest peacetime incidents in modern Korean history.
The aftermath transformed how Korea approaches large public gatherings. National mourning was declared, criminal investigations followed, and the bereaved families campaigned for years for an official memorial. In October 2025, the government held the first joint state commemoration at Gwanghwamun Square, attended by relatives of victims from 12 countries. Seoul also introduced crowd density maps, mandatory right-side walking lanes, and pre-deployed safety personnel in nightlife districts.
The New Halloween Scene: Hongdae, Sinchon, and Theme Parks
Itaewon never fully recovered as Halloween's center of gravity. In the years since the tragedy, crowds have shifted to Hongdae in Mapo-gu, the youth and indie music district around Hongik University. On Halloween night 2025, Mapo-gu Office estimated that 110,000 people gathered in the Hongdae Special Tourist Zone between 9 and 11 p.m., effectively matching pre-disaster Itaewon numbers. Nearby Sinchon, anchored by Yonsei and Ewha universities, has become a second hub aimed at students.
Beyond the street scene, theme parks now drive much of the Halloween economy. Everland in Yongin runs its Horror Maze and zombie performances every October, while Lotte World in Jamsil hosts costume parades and themed parties. Theme cafes across Seoul, including Hongdae's character cafes and dessert spots, lean hard into pumpkin and ghost decor through the month.
Korean Halloween Costumes: K-pop and K-drama Looks
Korean Halloween costumes tend to skew toward pop culture rather than the classic ghosts and witches popular in the West. K-pop idol cosplay is a huge category, with fans dressing as their favorite stage outfits, BLACKPINK's Kill This Love looks, ATEEZ pirate concepts, or vintage Girls' Generation school uniforms. Idols themselves set the tone every October by posting their own costumes on Instagram and Weverse.
K-drama characters are equally popular. Ji Eun-tak from Goblin, with her maroon hoodie, red scarf, and buckwheat flowers, has been a go-to for years. The squid mask and red jumpsuits from Squid Game became an instant global staple, and supernatural romances like My Demon and Beauty Inside also feed costume trends. Couples often dress as drama OTPs together.
Korean Halloween Treats and Convenience Store Snacks
Korean food companies treat Halloween as a major limited-edition season. Lotte's Pepero rolls out pumpkin and dark chocolate flavors, often in black and orange packaging that hits convenience store shelves throughout October. Tous les Jours and Paris Baguette compete with elaborate pumpkin tarts, ghost-shaped cream buns, and Frankenstein cupcakes, marketed heavily to families with young children.
Convenience store chains like GS25, CU, and 7-Eleven Korea release seasonal triangle kimbap with squid ink wrappers, pumpkin lattes, and ghost-shaped onigiri. Cafes such as Twosome Place and A Twosome Place introduce purple sweet potato and pumpkin Halloween drinks, while specialty bakeries in Seongsu and Yeonnam-dong build their entire October menus around the theme.
Halloween in K-Content and Fan Culture
K-dramas frequently use Halloween as an emotional or supernatural beat. Goblin uses the season's afterlife symbolism, My Demon plays with devil and angel imagery, and Beauty Inside built episodes around masquerade themes. Variety shows like Running Man and Knowing Bros stage annual Halloween specials with elaborate cast costumes that fans dissect frame by frame.
K-pop fan culture has built its own Halloween rituals. Fan accounts compile annual roundups of idol costumes, light stick decorations get pumpkin add-ons, and Hongdae dance studios host fan cover events themed around Halloween-coded songs like Dreamcatcher's discography or Stray Kids' Thunderous. For international fans, the season is a global moment of shared participation, even when the actual costumes never make it past an Instagram story.
