Japanese anime imports continue their dominant run at South Korean multiplexes, with "Chiikawa the Movie: The Secret of the Mermaid Island" refusing to yield its box office crown despite fresh competition from local prestige fare.

The Toho-distributed film claimed nearly 45 percent of nationwide ticket revenue during the Oct. 23-25 weekend, data from KOBIS (Korean Film Council's official tracking service) reveals. The accomplishment marks the anime's fourth consecutive week commanding South Korea's theatrical landscape, a tenure that underscores the genre's accelerating appeal across East Asian markets beyond Japan's domestic borders.

The persistence of "Chiikawa" represents a notable shift in South Korean moviegoing habits. Historically, local audiences showed strong preference for homegrown productions, yet anime films have systematically eroded that insularity over the past five years. Studio Ghibli's theatrical re-releases paved the way, but recent original anime productions like "Suzume" and now "Chiikawa" demonstrate that Japanese animation can sustain box office momentum against any competitor, including major Korean releases.

That test came this weekend with the arrival of "Paradise Lost," a thriller helmed by Yeon Sang-ho, one of South Korea's most distinctive genre architects. Yeon, whose previous films include the zombie thriller "Peninsula" (2020) and the dark comedy "Hellbound!" (2021), brings formidable pedigree to the marketplace. Yet "Paradise Lost" could only capture secondary positioning upon debut, a telling indicator of "Chiikawa's" gravitational pull on audiences.

The anime's fourth-week staying power defies typical theatrical windows. Most films, animated or otherwise, experience substantial drops after their opening weekend. That "Chiikawa" maintains near-half the box office suggests either saturation among devoted anime fans or the kind of word-of-mouth momentum that extends beyond core enthusiasts to general audiences. The film's premise—a mystery adventure centered on a mermaid island—carries accessible, family-friendly appeal alongside anime's traditional devotee base.

"Chiikawa's" performance carries broader implications for international distribution strategy. Toho's commitment to wide South Korean releases reflects confidence that anime represents a reliable revenue stream in non-Japanese territories. This contrasts sharply with the traditional model, wherein anime relied on festival circuits and specialty distributors before reaching mainstream theatrical screens. Now major Japanese studios treat South Korean multiplexes with the same strategic priority as domestic Japanese venues.

For Yeon Sang-ho and "Paradise Lost," the crowded marketplace presents a different calculus. Korean thrillers typically perform strongest during peak seasons or facing diminished competition. Mid-October releases often contend with both summer stragglers and holiday-period buildups. Yeon's track record should eventually position "Paradise Lost" for solid performance, but the immediate ceiling imposed by anime's sustained dominance complicates his film's trajectory.

The broader pattern reflects the entertainment market's globalization. South Korean audiences now consume anime with the same casual familiarity their predecessors reserved exclusively for Korean cinema. That normalization matters beyond box office receipts. It signals how thoroughly Japanese cultural products have penetrated Korean popular consciousness, a development that would have seemed inconceivable during earlier eras when national cinema stood more fortified against external competition.
