Satomi Korogi
Chi (voice)

An American Shorthair kitten wanders away from her mother and siblings one day while enjoying a walk outside. Lost in her surroundings, she struggles to find her way back home. She is soon found by the Yamada family. Finding a home for her proves to be difficult, so the family eventually decides to keep the kitten, naming her "Chi."
Chi’s Sweet Home (2008) may look like a simple slice-of-life anime about a lost kitten, but its behind-the-scenes casting reads like a who’s who of Japan’s voice-acting elite. The series, which ran for 104 five-minute episodes, became a surprise hit thanks to its adorable premise—and the star power behind its tiny protagonist.
The role of Chi, the mischievous American Shorthair kitten, went to Satomi Korogi, a veteran seiyuu best known for voicing **Himawari Nohara in Crayon Shin-chan and Misty’s Togepi in Pokémon . Korogi’s ability to convey Chi’s wide-eyed curiosity and playful antics with just her voice helped turn the character into an instant fan favorite. The rest of the cast was no less impressive: Noriko Hidaka** (Digimon, Ranma ½) as Mom, Hidenobu Kiuchi (Bleach, Naruto) as Dad, and Etsuko Kozakura (Sazae-san, Doraemon) as Yohei Yamada, the young boy who adores Chi
.
What’s striking is how such high-profile actors committed to a series with such short episodes. Chi’s Sweet Home originally aired in five-minute chunks, a format more common for experimental or low-budget projects [1]. Yet the cast’s consistency—each actor reprised their role for all 104 episodes—suggests the production had serious backing, likely from TV Tokyo and Madhouse, the studio behind the adaptation [9].
In 2010, an OVA (original video animation) titled Chi’s Sweet Home: Chi to Kocchi, Deau was released, clocking in at just 15 minutes . Unlike the TV series, details about its production are scarce. The OVA’s existence is confirmed, but whether the original cast returned—or if it was a one-off experiment—remains unconfirmed in the available evidence. Given the main cast’s long-term commitment to the series, it’s plausible they participated, but without explicit credits, this stays in rumor territory.
The series’ charm lies in its minimalist storytelling—Chi’s adventures are told almost entirely through her perspective, with little dialogue. Yet the cast’s performances elevate even the simplest moments, like Chi’s first encounter with a vacuum cleaner or her attempts to befriend a neighborhood dog. The fact that all seven main cast members stayed for the entire run suggests they found the project creatively rewarding, despite its unconventional format [1][2].
Chi’s Sweet Home never had the budget of a Studio Ghibli film or the action of a Shonen Jump adaptation, but its cast’s dedication helped it endure. Korogi’s portrayal of Chi became iconic enough to earn her a Wikipedia entry highlighting the role [8], while the series itself spawned manga, merchandise, and even a 2016 sequel, Chi’s Sweet Adventure (though with a mostly new cast).
For fans, the original 2008 series remains a testament to how great voice acting can turn even the simplest premise into something unforgettable.
