Zengo Yoshida was an admiral in the Imperial Japanese Navy.

Mutsu (陸奥) was the second and last Nagato-class dreadnought battleship built for the Imperial Japanese Navy (IJN) at the end of World War I. She was named after the province. In 1923 she carried supplies for the survivors of the Great Kantō earthquake. The ship was modernized in 1934–1936 with improvements to her armour and machinery, and a rebuilt superstructure in the pagoda mast style.
