Koala's Diary

こあらえにっき

Aired: 2025 - 2026

An anime produced by studio MOTHER, based on the manga of the same name by Yuami published by KADOKAWA, with volumes 1-5 currently on sale. A short anime streaming every Thursday at 8:00 PM on the official "Koala's Diary Channel" on YouTube. Koala-san's daily life is gentle and warm. Getting discouraged by failures, feeling happy about successes—each event may seem small, but every day, whether things go well or not, whether it's a special occasion or just an ordinary day, is precious. With the catchphrase "Today is a good day, tomorrow will be a good day too," this unique production features voice actress Aya Uchida performing all characters including Koala-san, Kuma-chan, Karasu-san, Emu-san, and Harinezumi-san. Directed by Takao Kato, with character design by Chiharu Hara and music by Atsushi Umebori and Swabecc Kowalewski. The theme song "Nijito" is performed by Punipuni Denki feat. Kan Sano, whose warm sound rooted in jazz and bossa nova complements the series' atmosphere. (C) Yuami, KADOKAWA / Koala's Diary
