Japan is an island country located in the Pacific Ocean, off the eastern coast of the Asian continent. It has five main islands – Honshu, Hokkaido, Kyushu, Shikoku, and Okinawa. The Emperor of Japan is currently the only sovereign in the world with the English title of “emperor”. The Japanese Imperial Family is the longest-reigning dynasty in the world. The first known Emperor was Jimmu who lived from 660 B.C. to 585 B.C. The Imperial Family is therefore approximately 2,600 years old. The Japanese believe that Emperor Jimmu was descended from the Sun Goddess, Amaterasu, who created Japan. All subsequent Japanese emperors have claimed descent from Emperor Jimmu and, as a result, they were revered as a living God. In 1946, Emperor Shōwa (Hirohito) renounced his divinity by publicly announcing, “I am no more divine. I am a human.”
In the Japanese Imperial Family and among the Japanese people, there are very specific naming conventions. Information can be found at Japanese Naming Conventions. One of the naming conventions which will be noticed in the index below is that Emperors have two names. Since the modern era, the reign of Emperor Meiji 1867 – 1912, a deceased Emperor is referred to by his posthumous name, which is the name of the era coinciding with the Emperor’s reign. Emperor Meiji was born Prince Mutsuhito but having ruled during the Meiji Era, he is posthumously known as “the Meiji Emperor” or simply “Emperor Meiji”. Deceased Empresses are also given a posthumous name. After the death of Emperors and Empresses, their posthumous names are the only names that Japanese speakers use when referring to them.
