Tatsunoko Production Co., Ltd., often shortened to Tatsunoko Pro. (竜の子プロ or タツノコプロ), is a Japanese animation company founded in 1962 by acclaimed anime pioneer Yoshida Tatsuo along with his brothers Kenji and Toyoharu (Toyoharu adopted the pen name Ippei Kuri to distinguish himself from his brothers). The studio's name has a double Japanese meaning of "Tatsu's child" (Tatsu being a nickname for Tatsuo) and "seadragon" which was the inspiration for its seahorse corporate logo.
