Over the past few years, and especially in 2025, Demon Slayer has become more than just a popular anime/manga series in Korea. It’s reached a level of cultural phenomenon. Here are some of the key reasons:
Record-breaking box office & fast uptake
- Demon Slayer: Kimetsu no Yaiba – Infinity Castle crossed 2 million admissions in just 5 days after its release in Korea, the fastest for any film in 2025.
- It later surpassed 4 million tickets sold, becoming the No. 3 Japanese animated film ever in Korea (by admissions), overtaking Your Name.
- It maintained the #1 spot in the Korean box office for many consecutive days/weeks.
Strong pre-sales & fan anticipation
- Advance ticket sales were extremely high (84% pre-sales at some points), showing strong demand before the film’s release.
- Audiences are also rating it very highly (CGV’s Golden Egg Index etc.) which helps word-of-mouth.
Cultural resonance and cross-media appeal
- The animation, storytelling, visuals are high quality. The emotional arcs (family, sacrifice, friendship) appeal broadly.
- Merchandise & fashion collaborations (e.g. with UFC Sports via Gwangju Shinsegae) show that Demon Slayer characters are being woven into everyday culture.
Global anime boom & streaming / fan culture
- With increased accessibility via streaming, strong community building (fan art, cosplay, social media), anime in general has more mainstream acceptance.
- Demon Slayer already had momentum before “Infinity Castle” but this iteration catapulted its popularity even higher in Korea.
