On July 24, 2026, Chiikawa the Movie: The Secret of Mermaid Island, the eagerly anticipated first film version of Chiikawa, will be released. The primary image for every character in this work, including Siren and Shima Jiro's initial look, has been released.

The Inspiration Behind the New Arc
The manga "Chiikawa" was illustrated by illustrator Nagano and produced by X (previously Twitter). Readers have been enthralled by the humorous, depressing, and even challenging everyday tales delivered by distinctive characters like Chiikawa, Hachiware, and Usagi since the serialisation started in 2020. It has won the Japan Character Awards Grand Prix three times and is incredibly popular across all generations. With almost 400 million missed broadcasts on YouTube, the anime, which started airing in 2022, is drawing interest from both Japan and the rest of the world.
Behind the Scenes of the Movie
The first movie adaptation of the series, Chiikawa the Movie: The Secret of Mermaid Island, features the Siren Edition, a distinctive and well-liked full-length episode. Cypic, which is renowned for its excellent animation—including the intense action sequences in the film “Uma Musume Pretty Derby: Door to a New Era”—will create the movie. The adventures of Chikawa and his companions are interwoven with stunning music and striking images under Nagano's close supervision.
Images of Chikawa, Hachiware, and Usagi travelling to an island were featured in the 60-second special that was broadcast the other day, along with breathtaking views of the fields and seas and a gorgeous orchestral rendition of "Hitorigotsu." Because of the visuals exclusive to the theatrical edition, expectations are growing as the movie gets closer to its premiere.
Every character from this work is depicted in this primary image. You can see flying squirrels playing in the waves at their own pace, a second-hand bookshop, a chestnut bun, a Shisa, a sea otter with a strong back view, and a Chikawa with what appear to be red scales in his hand, a Hachiware with a sharp expression on his face, and a rabbit holding the weapon "Binyoyo" given to him on the island.
It also shows Hitoha and Futaba, the islanders holding hands, Jiro Shima, who draws attention with his delectable apron, and the sirens and mermaids, who are significant characters in this piece. On this verdant island with gorgeous blue skies, blue seas, and vibrant flowers, what will happen? I can't stop watching the news to see if there are any updates.
