Japanese Emperor Akihito is reported to intend to abdicate his throne.
Japan is a nation of a constitutional sovereign. The Emperor reigns over the country, but he is just the symbol of Japan and the integration of Japanese society. The Emperor abandoned the administrative power of the government and the army of Japan following the end of WWII.
Thus, the Emperor takes a role in some national ceremonies. He admits the inauguration of Prime Minister, confer a decoration to people having contributed to Japan, and do other honorable works.
Akihiro seems to be concerned about his health, being afraid of incomplete devote. Therefore, he is planning to resign the seat of Emperor within some years.
BBC: Japanese Emperor Akihito 'plans to abdicate'
In the ancient era, many Japanese Emperor gave their status to his successor. Some of the ex-Emperors still possessed the political power after the abdication. However, since Meiji period (1868), no Emperors have withdrawn his throne during their ages. Actually, current Imperial Household Law suggests no rules about intentional abdication. Therefore, Akihiro's announcement will inflict an argument.
As a Japanese, I respect Akihiro's idea. It will be good for him to be relieved from busy work and take care of himself. Recently, Roman Pope also resigned alive.
