Emperor Seinei was the 22nd emperor of Japan, according to the traditional order of succession. He is best known for events that took place before and after his reign with a void in between. These include a rebellion which was quickly put down, and a succession crisis as the Emperor had no children. Because Seinei had such a low profile, historians have questioned his existence and whether he ever ascended to the throne. Born: 444 Died: 484 In office: 480 – January 1, 484 Wiki link
