Masahito, Prince Hitachi (常陸宮正仁親王, Hitachi-no-miya Masahito Shinnō^?, born 28 November 1935) is a member of the Imperial House of Japan and the younger brother of current Emperor Akihito. He is the second son and sixth born child of Emperor Shōwa and Empress Kōjun and is fourth in line to the Chrysanthemum Throne. Prince Hitachi is mainly known for philanthropic activities and his research on the causes of cancer.

Born at the Tokyo Imperial Palace, Prince Masahito held the childhood appellation Prince Yoshi (義宮正仁親王, Yoshi-no-miya Masahito Shinnō^?).

He received his primary and secondary schooling at the Gakushūin Peers' School. In late 1944, the Imperial Household Ministry evacuated Prince Yoshi and the Crown Prince to Nikkō, to escape the American bombing of Tokyo.

After the war, from 1947 to 1950, Mrs. Elizabeth Gray Vining tutored both princes and their sisters, the Princesses Kazuko, Atsuko, and Takako, in the English language. Her account of the experience is entitled Windows for the Crown Prince (1952).
