Sensor Tower published a report on September 8 analyzing how the movie Chiikawa: The Secret of the Mermaid Island affected Chiikawa Pocket. On the film's July 24 release date, downloads of the idle RPG reached nearly 10,000, more than six times the previous day, driven by a commemorative campaign and the Mermaid Island event. Downloads stayed above 10,000 daily from July 29, and the game held a top 15 iPhone download ranking for a month.
The film is based on Nagano's manga Chiikawa and opened July 24, 2026. Chiikawa Pocket, an idle RPG from Applibot, launched March 27, 2025 on iOS and Android. Sensor Tower's report credits the release commemorative campaign and the new Mermaid Island event for the jump. The analysis also covered website traffic to major cinema chains and the Chiikawa collaboration with Kura Sushi, which Sensor Tower cited as signs of the franchise's broad economic impact in Japan's summer of 2026.
