All the Countries You Didn't Know Had Royal Families

Japan's Yamato dynasty goes back to 660, according to The Washington Post, and its current ruler is Emperor Akihito. He has reigned since 1989 and will be the first ruler of Japan in over two centuries to be allowed to abdicate the throne come December 2018 (around his 85th birthday), The Telegraph revealed.

Akihito will be stepping down as emperor — from the Chrysanthemum Throne, which sits in the Imperial Palace — in order to give the throne to his oldest son, Crown Prince Naruhito.
