Hirohito, posthumously in Japan officially called Emperor Shōwa was the 124th Emperor of Japan according to the traditional order, reigning from December 25, 1926 until his death in 1989. Although better known outside of Japan by his personal name Hirohito, in Japan he is now referred to primarily by his posthumous name Emperor Shōwa. The word Shōwa is the name of the era that corresponded with the Emperor's reign, and was made the Emperor's own name upon his death. The name Shōwa means "abundant benevolence".
At the start of his reign, Japan was already one of the great powers — the ninth largest economy in the world after Italy, the third largest naval country, and one of the five permanent members of the council of the League of Nations. He was the head of state under the limitation of the Constitution of the Empire of Japan during Japan's imperial expansion, militarization, and involvement in World War II. After the war, he was not prosecuted for war crimes as many other leading government figures were, despite his involvement.. During the postwar period, he became the symbol of the new state and Japan's recovery, and by the end of his reign, Japan had emerged as the world's second largest economy.
