It was founded in October 1962 by anime pioneer Tatsuo Yoshida and his brothers, Kenji and Toyoharu (pen name "Ippei Kuri").[2] The studio's name has a double meaning in Japanese: "Tatsu's child" (Tatsu is a nickname for Tatsuo) and "sea dragon", the inspiration for its seahorse logo.[2][3] Tatsunoko's headquarters are in Musashino, Tokyo.
