Hirohito
Hirohito was the 124th emperor of Japan according to the traditional order of succession, ruling over the Empire of Japan from 25 December 1926 until 2 May 1947, after which he was Emperor of the state of Japan until his death. He was succeeded by his fifth child and eldest son, Akihito. Hirohito and his wife, Empress Kojun, had seven children, two sons and five daughters. In Japan, reigning emperors are known only as "the Emperor." He is now referred to primarily by his posthumous name, Shōwa (昭和), which is the name of the era coinciding with his reign; for this reason, he is also known as the Shōwa Emperor or Emperor Shōwa. By 1979, Hirohito was the only monarch in the world with the title "emperor." Hirohito was the longest-lived and longest-reigning historical Japanese emperor and one of the longest-reigning monarchs in the world.
