TOMOO Brings a New Track to the Franchise's Big Screen
Singer-songwriter TOMOO, who performed the opening theme "Contrast" for Blue Box, will sing the original theme song "Otona ni Nattara" (When I Grow Up) for the upcoming Crayon Shin-chan film. Japanese anime news site Anime Hack reported that TOMOO wrote the song specifically for the movie, alongside the release of a full trailer and new poster visual.
The movie's full Japanese title is Eiga Crayon Shin-chan: Kiki Kaikai! Ora no Yokai Bake~shon (映画クレヨンしんちゃん 奇々怪々！オラの妖怪バケ～ション). It marks the 33rd theatrical entry in the long-running franchise based on Yoshito Usui's manga, published by Futabasha. Shin-Ei Animation produces the film, with Toho handling distribution.
What the Trailer Reveals
The new trailer previews a summer story in which yokai begin appearing across Japan after a mysterious incident. The Nohara family gets pulled into the yokai world, where Misae (Miki Narahashi) and Hiroshi (Toshiyuki Morikawa) have their "oshiridama" extracted and are transformed into yokai themselves.
Shinnosuke (Yumiko Kobayashi) teams up with a fox yokai named Yako, voiced by Sairi Itō (Midori Asakusa in Keep Your Hands Off Eizouken!, Rumi in Suzume). Together they set out for the Nanka Yokai Castle to reverse the transformation. Standing in their way is Kumada no Osa (Shunsuke Sakino), who rules the yokai realm, and his servant Hyakuemon, played by Yūki Kaji (Eren Yeager in Attack on Titan, Shoto Todoroki in My Hero Academia).
The trailer also shows Yako conflicted about befriending humans, and scenes of yokai outbreaks spreading across the country. The new poster visual features Shinnosuke in tengu-like garb reaching for an oshiridama, surrounded by the Nohara family and their yokai travel companions in a yokai-world castle town. The tagline reads: "I'll never give up!!"
TOMOO on Writing the Theme
In her official comment, TOMOO shared that Crayon Shin-chan was a childhood favorite. She recalled her mother telling her that whenever the show came on, she and her brother would stop fighting and laugh together in front of the TV.
She described the film as full of heart toward things that are invisible or hidden, a sensibility she shares. "Otona ni Nattara," she said, grew from the movie's story, scenery, and characters into a song about wanting to believe in excitement, nostalgia, and the important things that stay close even when you can't see them.
Looking Ahead
The film opens in Japanese theaters on July 31, 2026, timed for the summer holiday season. Masaki Watanabe directs in his first turn leading a Shin-chan theatrical feature, with a screenplay by Yoshiko Nakamura.
No international distribution or streaming partner has been announced. Previous Crayon Shin-chan films have reached international audiences through various channels, with some recent entries screening theatrically in select Asian markets. Shin-chan fans outside Japan will want to watch for a Crunchyroll or regional theatrical pickup as the release date approaches.
The source manga by the late Yoshito Usui continues under Futabasha. English-language Crayon Shin-chan manga has been published by CMX (now defunct) and One Peace Books in the past, though availability varies.
