Photograph of Emperor Hirohito of Japan (known posthumously as the Emperor Showa), with Queen Elizabeth II to his left. The Empress Nagako (known posthumously as the Empress Kojun) and Prince Philip, Duke of Edinburgh are on the right. The Queen and The Duke are wearing the insignia of the Order of the Chrysanthemum, Japan's highest award, which was established in 1876, whilst the Emperor wears the insignia of the The Order of the Garter, Britain's highest award. The photograph was most likely taken during the return reception at the British Embassy in Tokyo.
