Government of Japan
The Current Emperor of Japan (今上天皇) is Akihito. He was officially enthroned on November 12, 1990. He is styled as "His Imperial Majesty" (天皇陛下), and his reign bears the era name of Heisei (平成). Naruhito, the Crown Prince of Japan, is the heir apparent to the Chrysanthemum Throne.
Government of Japan
The Emperor is known to hold the nominal ceremonial authority. For example, the Emperor is the only person that has the authority to appoint the Prime Minister, even though the Diet has the power to designate the person fitted for the position. One such example can be prominently seen in the 2009 Dissolution of the House of Representatives. The House was expected to be dissolved on the advice of the Prime Minister, but was temporarily unable to do so for the next general election, as both the Emperor and Empress were visiting Canada.
