Chiikawa The Movie: The Secret of Mermaid Island Official Release Date Announced
The wait is finally over for fans of the "small and cute" sensation. It has been officially confirmed that the release date for the upcoming film, Chiikawa The Secret of Mermaid Island, is set for July 24th. This movie is based on the original work by the talented illustrator Nagano, whose creations have truly taken over the internet lately. Along with the date, a special report has also been dropped, giving us a first real look at the main footage from this highly anticipated theatrical venture.

This new film, Chiikawa the Movie: The Secret of Mermaid Island, is actually an adaptation of one of the manga's most legendary and long-running story arcs. Fans usually call it the Siren Edition because of its slightly darker and more adventurous tone compared to the daily life shorts. The story begins when a rather suspicious-looking flyer leads Chiikawa and his friends toward an island training camp. Of course, things are not going to be as simple as they look, and many trials are waiting for the trio once they reach their destination.
Production Details and Voice Cast
The movie is being handled by Cygames Pictures, and they have brought in Kei Oikawa to direct the project. For the fans who have been following the TV series, there is good news because the original voice cast is returning to breathe life into the characters on the big screen. The cast members include:
- Haruka Aoki as the voice of Chiikawa
- Masato Tanaka as the voice of Hachiware
- Ari Ozawa as the voice of Usagi

Several scene cuts were also shared alongside the trailer. One shot shows Chiikawa and Hachiware looking super excited from the back as they board the ship. Another one features Usagi just casually lying on a tree stump, being his usual chaotic self. There is also a very dignified shot of Chiikawa and Hachiware holding their Sasumata weapons, looking ready for whatever danger the island might throw at them.
