Key Visual Released for Chiikawa's First Movie "Mermaid Island": Giant Siren and Shimanijiro Take the Stage!

One of Japan's most beloved phenomena, Chiikawa, is preparing to hit the big screen! The long-awaited key visual for the series' first feature-length film, Eiga Chiikawa: Ningyo no Shima no Himitsu (Chiikawa Movie: The Secret of the Mermaid Island), has finally been shared with fans. The film, which will be released in Japan on February 7, 2025, covers one of the series' most beloved and mysterious story arcs.
In the newly released visual, along with our main characters Chiikawa, Hachiware, and Usagi, the key figures of this adventure, Shimanijiro and the massive Siren, stand out. The visual successfully reflects the mysterious atmosphere of the island and the great danger the characters will face. In particular, Shimanijiro's determined stance with arms crossed has already created a huge wave of excitement among fans who know this part of the manga.
So, why is the Chiikawa world so popular? Created by artist Nagano, the series first began with short drawings on Twitter (X). With its deep and sometimes dark narrative structure that contrasts with its name, which means "something small and cute," it has become a favorite among adults as well. The short-episode TV anime produced by Doga Kobo studio is watched by millions of people every morning in Japan, and character merchandise is breaking sales records. The series, which won the Japan Character Award in 2022, is considered one of the most important parts of modern pop culture.
This film is a major turning point for fans of the series. The "Mermaid Island" arc is known as one of the longest and most emotionally deep chapters of the manga. In the film, we will witness moments that test the friendship and courage of our team as they pursue the mysterious events on the island. The production, which will be released in early 2025, is already at the top of the list of the most anticipated anime films of the year. Let's see how our little heroes will deal with this giant Siren!
