In the Japanese constitutional monarchy, the emperor does not have any political power. In world politics, he is the only current emperor. The current emperor is His Imperial Majesty the Emperor Akihito. He has been on the Chrysanthemum Throne since his father Emperor ShÅwa (Hirohito) died in 1989. The amount of power belonging to the emperor of Japan has changed a lot throughout Japanese history.
The era name assigned to the current Emperor is âHeisei'. Japanese years are calculated by the number of years the Emperor has reigned. The year 2015 is the 27th year of the reigning Emperor, so this year is therefore âHeisei 27', commonly written as the first letter of the era name then year number, i.e. âH27â².
