Sirotan TV Anime Set for Fall 2026 Premiere
Creative Yoko has announced that a new television anime series based on the character Sirotan will premiere in Japan in the fall of 2026.
The upcoming series celebrates the legacy of the character, a white harp seal that was first created in 1999 and has since appeared in various merchandise and media.
A teaser trailer and visual for the production were released on March 22, 2026, alongside the launch of the official website and social media accounts.
Yuki Aoi, known for her role in The Apothecary Diaries, is confirmed to return as the voice of Sirotan after previously voicing the character in a 2017 web series.
The project is being planned and produced by TV Asahi and Shin-Ei Animation, with the animation production being handled by the studio Lesprit.
Arisa Okada will direct the series, while Sei Yoshistuki is tasked with managing the series composition and writing the scripts.
This new television adaptation follows a 24 episode web series titled Sirotan: Sirotan ga Ippai! which originally debuted on YouTube on August 12, 2017.
Sirotan remains a popular mascot for Creative Yoko, a Japanese company specializing in general merchandise and products for pets.
