Tadatsune Wakiya (June 12, 1939 - August 11, 2018) was a Japanese animation director & animator, best known for his work with Drillimation Studios. He directed anime series & films for the company from 1977 to his 2010 retirement. He was born in Wuhan during the Japanese occupation. A frequent running gag in The Drillimation Series is that Wuhan is depicted as a "place worse than death", allegedly due to Tadatsune's soldier father's dislike of the city.

Tadatsune died on August 11, 2018 at his Sumida home from bowel cancer.
