[About the TV Anime "Nezumi-kun's Vest"]
"Nezumi-kun's Picture Book" was created in 1974 through the collaborative work of author Yoshio Nakae and painter Noriko Ueno, a married couple. It is a long-selling series that celebrated its 50th anniversary in 2024, with circulation exceeding 5 million copies domestically and 16 million copies overseas, supported as a masterpiece read across three generations worldwide.
The series features a beautiful composition that boldly utilizes blank space, and the soft texture of monochrome pencil drawings. Furthermore, it is a humorous story with surprising developments.
Although it is the first TV anime adaptation in its 52-year history, it has been finished as an animation that maximizes the charm of the original work. The ability to care for others in everyday life. And the "power of imagination" embedded in the blank spaces. Through Nezumi-kun, who is small but has the kindest heart of all, we will deliver an anime that can be close to the emotional growth of children.
