Tada Yoshitoshi (多田 義俊, 1698-1750) was a Japanese samurai and scholar of kokugaku, known during his lifetime as an expert on ancient court ceremonial practices. He published picture books (ezōshi) under the pen nameTada Nanrei (多田 南嶺), and also wrote under the names Shundō (春塘) and Shūsai (秋斎). His full official name was Tada Hyōbu Minamoto no Mitsuyasu (多田 兵部 源 満泰).[1]
He studied Chinese literature as well as the Suika Shinto of Yamazaki Ansai under Aoki Kazue (青木 主計) at Osaka. Tada subsequently became an active teacher of court ceremony and Shinto studies in that city. Later, he travelled to Kyoto to participate in research under the scholar Tsuboi Yoshichika [ja]. However, he was expelled by Tsuboi after publishing an essay in which he questioned the credibility of the Kuji Hongi.[2]
