As an ensign, he served aboard cruiser Tokiwa. On 13 Dec 1915, he was promoted to the rank of sub-lieutenant and served aboard battleship Kongo and destroyer Urakaze.

At the start of the Pacific War, Daigo was the commanding officer of Submarine Squadron 5 with flagship light cruiser Yura. His force covered the first wave of the Malaya Invasion Force south of the Cape of Camau in French Indochina; during that campaign, his submarines were dispatched to pursue the British Royal Navy Force Z that included Prince of Wales and Repulse, but they were unable to attack due to weather before the British were sunk by aircraft.
