Sgt. Frog is getting a brand-new TV anime: Bandai Namco Pictures confirmed on September 7, 2026 that the Keroro Platoon returns with an entirely new voice cast, a first trailer, and an October 3 premiere on TV Tokyo — distinct from the returning cast used in June 2026’s anniversary film.
What Bandai Namco Pictures Announced
Bandai Namco Pictures (BN Pictures) released the first promotional video and key visual for an all-new Sgt. Frog TV anime on September 7, 2026, confirming a full cast reveal alongside the franchise’s already-known October debut. The series premieres October 3, 2026, at 9:30 a.m. on TV Tokyo and affiliate stations in Japan. No international streaming platform has been announced yet.
The reboot was first announced back on December 23, 2025, but today’s reveal is the first time Bandai Namco Pictures has shown footage, confirmed the full voice cast, or set an exact premiere time. Nobuhiro Kondō is chief director, Akihiko Sano directs at BN Pictures, Hatsue Nakayama designs the characters, Toshimitsu Takeuchi writes the series scripts, and Kan Sawada composes the score, with Bridge and AISLE credited for production cooperation.
Meet the New Keroro Platoon Cast
Every member of the five-frog Keroro Platoon gets a new voice actor for this series — none of them carry over from the 20th-anniversary theatrical film released three months earlier:
| Character | Rank | New Voice Actor |
|---|---|---|
| Keroro | Sergeant (platoon leader) | Makoto Koichi |
| Tamama | Private Second Class | Rika Nagae |
| Giroro | Corporal | Toshiki Masuda |
| Kululu | Sergeant Major | Kōsuke Echigoya |
| Dororo | Lance Corporal | Satoshi Inomata |
A New Cast for a Reason: Two Different Anniversary Projects
The all-new cast isn’t a shakeup so much as a signal of what kind of project this is. Bandai Namco Pictures is running two separate 20th-anniversary tracks for Sgt. Frog at once: a theatrical film that opened June 26, 2026 with the returning, established cast for longtime fans, and now a full television series with a ground-up new cast aimed at building a cast that can carry the franchise for another decade of episodes rather than one nostalgia-driven film run. That is the real reason today’s reveal matters more than a typical recast: it is a statement about which cast Bandai Namco Pictures expects to define Sgt. Frog going forward.
