Born in Hiroshima Prefecture, he began working at Nikkatsu's Kyoto studio in 1924 and eventually came to prominence for a series of realist, humanist films made at Nikkatsu's Tamagawa studio in the late 1930s such as Robō no ishi and Mud and Soldiers, both of which starred Isamu Kosugi. His war film, Five Scouts, was screened in the competition at the 6th Venice International Film Festival.
Tasaka was a victim of the atomic bombing of Hiroshima and spent many years recovering. He eventually resumed directing and won the best director prize at the 1958 Blue Ribbon Awards for A Slope in the Sun, which starred Yūjirō Ishihara.
