The future Fleet Admiral Mineichi Koga was a friend from his childhood. Yoshida was graduate of the 32nd class of the Imperial Japanese Naval Academy in 1904, ranking 12th out of 190 cadets. The Russo-Japanese War had just started, and he served as a midshipman on the submarine tender Karasaki, and participated in the Battle of Tsushima aboard the cruiser Kasuga. ^[1]

He attended naval artillery and torpedo school in 1906–1907, and was then assigned to the destroyer Asatsuyu followed by the cruiser Hashidate. As a lieutenant from 1909, he specialized in torpedo warfare, and graduated from the Naval Staff College in 1913.^[1] His classmates included Kōichi Shiozawa and Shigetarō Shimada.

Yoshida was promoted to lieutenant commander in 1915, and commander in 1919, serving in a variety of administrative positions, primarily concerned with training. After his promotion to captain in 1923, he was given his first command in 1924; the cruiser Hirado. He served as chief of staff of the Maizuru Naval District from 1924 to 1925.

He also strongly opposed the idea of war against the United States. He was forced to resign due to illness and opposition to the pact on 5 September 1940, just before the arrival of the negotiating team from Germany, and the treaty went ahead despite his strong misgivings.^[2]
