Katsumi Mochizuki is a Japanese manga artist and illustrator known for his mix of charming, expressive characters and educational storytelling. His drawing style, often close to shōjo manga, features big eyes and youthful designs that appeal to both children and young adults.
He graduated from Rikkyo University with a law degree but chose to follow a creative path. After debuting in a youth magazine, he began working with educational publishers like Froebel and Gakken, creating manga that helps children learn in a fun and engaging way.
Early in his career, Mochizuki worked on the controversial 1983 adult PC game 'Lolita Syndrome', released by Enix. The game was contentious but showed the first visuals of his later signature style; vivid, cute, edge-of-shōjo, expressive character design, which would become a key part of his manga!
His most famous character is definitely Bunny-chan, a friendly big-eyed girl who appears in many of Katsumi’s educational manga. Bunny-chan was the star of a long-running series teaching science and everyday knowledge in a playful, accessible way.
She is a cheerful, energetic girl with a very kind appearance making her instantly appealing and easy to recognize across different books. She plays the role of a friendly guide or teacher. She explains facts, introduces fun trivia, and helps readers explore science, nature, and everyday knowledge
Bunny-chan became a familiar face to children through publications by Gakken, Shogakukan, and Kodansha, and is often compared to another household name and educational mascot: Doraemon
Although not as big as Doraemon, Bunny-chan manga spawned an impressive franchise of manga, books, video’s, games, toys and much more
