Born at Tokyo Imperial Palace in Tokyo, Masahito held the childhood appellation Prince Yoshi (義宮正仁親王, Yoshi-no-miya Masahito Shinnō).
Masahito 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).
Prince Yoshi received his undergraduate degree in chemistry from the Faculty of Science at Gakushuin University in 1958. He subsequently did postgraduate work in the Faculty of Science at Tokyo University. In 1969, he became a Research Associate of the Japanese Foundation for Cancer Research specializing in the study of cellular division. The results of his research have been reported in the technical journals of the Japanese Cancer Association, as well as of the American Association for Cancer Research.
In 1997, Prince Hitachi received an honorary doctorate from George Washington University in the United States, and in April 2001 received another from the University of Minnesota. In March 1999, he became an honorary member of the German Association for Cancer Research, in recognition of his significant scientific contributions to the field of cancer research.

On 30 September 1964, the Prince married Hanako Tsugaru (born 19 July 1940), fourth daughter of the late Yoshitaka Tsugaru, a former count and a descendant of the daimyō of Tsugaru Domain. The following day, Emperor Shōwa granted him the title Hitachi-no-miya (Prince Hitachi), and authorization to start a new branch of the Imperial Family in celebration of his wedding.
Prince and Princess Hitachi have their official residence in a palace in large gardens off Komazawadori in Higashi, Shibuya.[1] They have no children.
In September 2021, the Japanese government considered plans to amend the Imperial Household Law and allow Prince Hitachi to adopt a male member of the former shinnōke or ōke collateral branches of the imperial family in an effort to address the Japanese imperial succession debate.[2]
