Nippon Animation is a Japanese animation studio. The company is headquartered in Tokyo, with chief offices in the Ginza district of Chūō and production facilities in Tama City.
Nippon Animation is known for producing numerous anime series based on works of Western literature such as Anne of Green Gables and The Adventures of Tom Sawyer. Hayao Miyazaki and Isao Takahata, co-founders of Studio Ghibli, directed several episodes in the World Masterpiece Theater series.
Nippon Animation is descended from Zuiyo Eizo (Zuiyo Enterprises), an animation studio that produced several popular series in the early and mid-1970s, including 1974's Heidi, Girl of the Alps, an adaptation of Johanna Spyri's popular children's book Heidi.
Officially, Nippon Animation Co., Ltd. was established on 3 June 1975 by company president Kōichi Motohashi.
Of the studio's productions not based on Western literature, the most popular is undoubtedly Chibi Maruko-chan (1990), based on the popular manga by Momoko Sakura.
At its peak, this slice-of-life anime about an unusually intelligent elementary-school-aged girl and her family and friends managed an audience rating of nearly 40%, making it one of the highest-rated anime series ever (and the highest-rated anime program in Japanese history at the time).
