In the 1920s, Hirohito served as Regent during several years of his father's reign, when Emperor Taishō was physically unable to fulfill his Imperial duties.
From 1946 to 1950 during the Allied occupation of Japan after the war, Vining was selected by Emperor Hirohito himself (and not the United States government, as is erroneously claimed) to become a private tutor to Crown Prince Akihito, the heir apparent to the Chrysanthemum Throne.
When the Emperor is riding inside, the Imperial Standard, known as the Imperial Seal of Japan is displayed at both the front and rear of the car in place of a license plate, and on the exterior of both rear passenger doors, displaying a 16 petal chrysanthemum, in golden colour, in reference to the Chrysanthemum Throne of Japan.
