A new Sgt. Frog (Keroro Gunso) TV anime premieres October 3, 2026 on TV Tokyo, the alien-frog invaders' first television series in over a decade. Bandai Namco Pictures is animating, with Nobuhiro Kondo as chief director and a fresh voice cast led by Makoto Koichi as Keroro.
The setup
Keroro and his hapless invasion platoon — Giroro, Tamama, Kululu, and Dororo — return to TV Tokyo's Saturday 9:30 a.m. slot on October 3. This is the franchise's first new TV series in years, rebooting the gag-comedy formula that made the original a Saturday-morning staple.
Who's making it
Bandai Namco Pictures handles animation, with production help from Bridge and AISLE. Nobuhiro Kondo is chief director and Akihiko Sano series director; Hatsue Nakayama designs characters and Kan Sawada scores. The new main cast: Makoto Koichi (Keroro), Toshiki Masuda (Giroro), Rika Nagae (Tamama), Kosuke Echigoya (Kululu), and Satoshi Inomata (Dororo).
How to read it
This is a nostalgia play aimed squarely at the Saturday-morning family audience, not the prestige seasonal lane. For long-time fans it's a genuine event; for everyone else it's a low-stakes gag comedy to sample. The original Keroro run sits in the mid-tier of SenpaiRanks' comedy ranking — solid, not essential.
