Sgt. Frog Is Back in 2026: The Keroro Movie, a New TV Anime (Oct 3), and What to Collect
Sgt. Frog (Keroro Gunso) is having its biggest year in more than a decade. In 2026 the franchise is running two projects at once: a 20th-anniversary theatrical film that hit Japanese cinemas on June 26, 2026, and a brand-new television anime, Keroro Gunso ☆, that premieres on October 3, 2026 with an entirely fresh voice cast. This guide lays out both, explains why there are effectively two Keroros this year, and points collectors to the Sgt. Frog Ichiban Kuji that ships from Japan.
- New movie: released in Japan on June 26, 2026 (20th-anniversary film, classic cast).
- New TV anime: Keroro Gunso ☆ premieres October 3, 2026 with an all-new cast.
- What it is: a comedy about a platoon of frog-like alien invaders stranded on Earth.
- To collect: a Bandai Spirits Sgt. Frog Ichiban Kuji tied to the movie's "Revival" campaign.
What Is Sgt. Frog, and Why Is It Back in 2026?
Sgt. Frog (Keroro Gunso) is a comedy manga and anime created by Mine Yoshizaki about a platoon of frog-like alien soldiers from the planet Keron who bungle their invasion of Earth and end up living with a Japanese family instead. The original TV anime began in 2004 and ran for seven years, making 2026 its 20th anniversary.
That anniversary is the reason for the double bill. Bandai Namco is celebrating with a nostalgia-first movie that reunites the long-running cast, and a separate reboot-style TV series that recasts the platoon for a new generation. If you grew up with the 2000s dub or are meeting Keroro for the first time, both entry points open within a few months of each other.
Collectors have a matching window: the merchandise wave built around the film is out now. Akibato ships the Sgt. Frog Keroro Ichiban Kuji from Japan if you want the platoon on your shelf while the revival is fresh.
The New Sgt. Frog Movie: The 20th-Anniversary Film (June 26, 2026)
The film opened in Japan on June 26, 2026 under the title Shin Gekijoban Keroro Gunso: Fukkatsushite Sokko Chikyu Metsubou no Kiki de Arimasu! — roughly "New Theatrical Movie Sgt. Frog: Upon Revival, Immediately Facing the Threat of Earth's Destruction!" It is the sixth Sgt. Frog film and the franchise's first theatrical release in 16 years; the last one came out in 2010.
Key details for the movie:
- General director and screenwriter: Yuichi Fukuda, known for the live-action Gintama films.
- Director: Fumitoshi Oizaki, with character designs by Satoshi Koike.
- Studio: BN Pictures.
- Cast: the classic voice cast returns, including Kumiko Watanabe as Keroro.
- New characters: two original brothers, Aruu and Deruru, tied to the platoon's past.
The story follows the Keroro Platoon investigating mysterious symbols and strange phenomena appearing across Japan. Singer ano performs a theme song for the project and serves as the film's 20th-anniversary campaign ambassador — a thread that carries straight into the TV series below.
Keroro Gunso ☆: The New TV Anime Premieres October 3, 2026
The reboot TV anime, Keroro Gunso ☆, premieres in Japan on October 3, 2026. Bandai Namco Pictures confirmed the date, staff, and main cast alongside a main trailer and key visual, then followed on September 14, 2026 with a second trailer revealing the theme songs and additional cast.
Production and staff:
- Chief director: Nobuhiro Kondo.
- Series director: Akihiko Sano.
- Studio: BN Pictures.
- Opening theme: "Kirai nochi Suki!" by ano.
- Ending theme: "Himitsu no Panorama" by PURPLE BUBBLE.
The all-new main platoon cast is:
- Keroro: Makoto Koichi
- Tamama: Rika Nagae
- Giroro: Toshiki Masuda
- Kururu: Kosuke Echigoya
- Dororo: Satoshi Inomata
The second trailer also introduced the human side of the cast: Yuki Sakakihara as Fuyuki Hinata, Minori Fujidera as Natsumi Hinata, Sumire Morohoshi as Momoka Nishizawa, Hiiro Ishibashi as Mutsumi Hojo, and Koko as Koyuki Azumaya.
New Cast vs. Classic Cast: Why 2026 Has Two Keroros
This is the part that trips up returning fans. The movie and the TV anime are separate productions with different voices, so which Keroro you hear depends on which one you watch.
- The movie (June 2026): nostalgia play — the original long-running cast returns, so Keroro sounds the way 2000s fans remember him.
- The TV anime (October 2026): a fresh start — a completely new cast led by Makoto Koichi as Keroro, aimed at building the series for a new audience.
- The connective tissue: singer ano appears on both, performing a theme for the film and the TV opening, which ties the anniversary year together.
If you only pick one, the movie is the sentimental choice and the TV anime is the jumping-on point. There is no wrong answer, and both sit inside the same 20th-anniversary celebration.
What to Collect: The Sgt. Frog Ichiban Kuji Tied to the Revival
The revival came with a Bandai Spirits Ichiban Kuji — an in-store prize lottery where every ticket wins something, from character figures down to smaller goods. The wave built around the film centers on the Keroro Platoon, with figures of Keroro, Tamama, Giroro, Kururu, and Dororo, plus a Last One Prize plush for the final ticket in a box.
Ichiban Kuji is sold physically in Japan and sells through quickly, so overseas fans usually rely on a shop that draws and ships. If you want to understand how the prize tiers and that final-ticket bonus work before you buy, our guide to the types of anime figures and our Zatch Bell Ichiban Kuji breakdown walk through the format on another nostalgic title.
Akibato stocks the Sgt. Frog Ichiban Kuji alongside other current lotteries and ships them from Japan, so you can add the platoon to your shelf while the anniversary attention is high.
How to Watch Sgt. Frog From Overseas
The honest answer for international fans: confirm the platform before you plan a binge. As of mid-September 2026, a widely announced English-subtitled simulcast partner for Keroro Gunso ☆ had not been broadly confirmed, and the June film was a Japanese theatrical release.
Practical steps:
- Check the major legal streamers (Crunchyroll and similar) for a Fall 2026 listing as October 3 approaches.
- Watch the official Sgt. Frog and Bandai Namco channels for simulcast and home-video news.
- For the classic run, the original 2004 series is the best way to catch up on the platoon before the reboot.
