Chocojiro is the main character of the anime Sakuyama Chocojiro, adapted from a popular chocolate biscuit snack. He is a round, fluffy brown creature described as a rare beast who lives on Chocodale Mountain. His personality is defined by a strong appetite and a cheerful, curious nature. Originally named simply Chocojiro, he adopted the full name Sakuyama Chocojiro after a human child visiting the mountain gave him a biscuit. When he tried combining the biscuit with chocolate, he was so delighted by the taste that he began imitating humans and gave himself the human-style surname and first name. His primary motivation is to share the joy of chocolate biscuits with others. He ends his sentences with a characteristic suffix that sounds like the word for chocolate, a verbal quirk that adds to his charm. In the story, two high school girls named TomoCho and NonP come to Chocodale Mountain and befriend him. Chocojiro learns human gestures and mannerisms by watching and mimicking the two girls, though his attempts are endearingly clumsy and awkward. The girls are drawn to his proud but imperfect efforts, and a warm friendship develops. Over the course of the anime, Chocojiro gradually grows more expressive and comfortable around his human companions, though he retains his own unique, slightly clumsy way of doing things. He does not possess any special supernatural abilities; his notable traits are his distinctive speech pattern, his love for chocolate biscuits, and his ability to bring a lighthearted, comforting presence to those around him.
