The animated feature Chiikawa: The Secret of Mermaid Island, which opened in Japan on 24 July 2026, has reached record-breaking heights. The film recorded an opening-day gross of ¥9.9 billion, surpassing the debut of the long-running Detective Conan series. The story follows the characters as they travel to a mysterious island to find rewards and food, only to encounter the Seiren monster and its companions. By late August 2026, the film surpassed 11 billion yen in cumulative box office revenue, attracting 7.66 million viewers. During the weekend of 21–23 August, the film maintained its first-place position, earning 1.242 billion yen over three days. Commercial momentum has extended to retail, with stores like Watts offering Chiikawa-themed stationery, such as pen cases and masking tape, for 110 yen. The film’s success is attributed to its blend of whimsical adventure and darker themes. Based on the ‘Siren Arc’ from Nagano’s manga, the narrative has sparked discussions regarding the contrast between its cute art style and its heavy, unsettling themes. This has drawn comparisons to other works that use adorable aesthetics to mask intense storylines, such as Sanrio’s ‘Chirin no Suzu’ and ‘Hello Kitty: Princess of the Magic Forest,’ as well as ‘Happy Feet.’ Within 30 days of its release, the film became the fourth animated film in 2026 to surpass the 10 billion yen milestone, following ‘Zootopia 2’, ‘Detective Conan: Highway Angel’, and ‘Toy Story 5’. By 31 August 2026, the film’s box office revenue grew to 12.2 billion yen with 8.49 million admissions. Commercial activity continues to expand through various collaborations. Starting 5 September 2026, a fourth round of theater admission bonuses will offer random charm mini-figures of characters such as Shimajiro, Siren, Hitoha, and Futaba.
