Chiikawa the Movie: The Secret of the Mermaid Island held on to the top spot for its fifth weekend from August 21–23, according to Kogyo Tsushinsha. Originally released on July 24 with a first-place debut, the film slipped to second behind Spider-Man: Brand New Day only once in its second weekend, but has since reclaimed and maintained the position for three consecutive weekends.Chiikawa the Movie grossed 1.242 billion yen (7.8 million USD) with 825,800 admissions over the weekend of August 21-23, up 39% from the previous weekend. Even though the film was in its fifth weekend of release, the box office boost likely came from the third round of audience bonuses: the "Gokigen Siren♪", pullback mini-cars available in three designs, began being distributed on August 22. During the weekend of August 7-9, when the second bonus item, "Bonbon Drop Stickers," was distributed, box office revenue also jumped by 158.5% compared to the previous weekend. Chiikawa the Movie has reached a cumulative total of 11.05 billion yen (69.46 million USD) from 7.66 million admissions. It now ranks 42nd on Japan's all-time box office chart, surpassing Chainsaw Man - The Movie - Reze Arc (2025 / 10.83 billion yen) and EVANGELION:3.0+1.0 THRICE UPON A TIME (2021 / 10.28 billion yen).
In its fourth weekend of release, Eiga Crayon Shin-chan: Kikikaikai! Ora no Yokai Vacation (Crayon Shin-chan the Movie: Very Bizarre! My Yokai Vacation), the 33rd installment in the Crayon Shin-chan anime feature film series, climbed one spot to fifth.
Kingdom: Tamashii no Kessen (The Clash of Souls), the fifth installment in the Kingdom live-action film franchise, dropped two spots to seventh in its sixth weekend. The film has grossed 6.1 billion yen (38.35 million USD) on 4 million admissions, making it the second-highest-grossing entry in the series, behind the fourth film, Kingdom: Return of the Great General (2024 / 8.03 billion yen).
The live-action film adaptation of the BLUE LOCK manga series created by Muneyuki Kaneshiro (story) and Yusuke Nomura (art) went up one spot to ninth in its third weekend.
Shiranuhi, a new original anime short film from CoMix Wave Films (Your Name., Suzume), opened in 20 theaters on August 21 and took second place in Kogyo Tsushinsha's mini-theater ranking.
