Emperor of Japan
Currently, the Emperor of Japan is the only head of state in the world with the English title of "Emperor". The Imperial House of Japan is the oldest continuing monarchical house in the world. The historical origins of the Emperors lie in the late Kofun period of the 3rd–7th centuries AD, but according to the traditional account of the "Kojiki" (finished 712) and "Nihon Shoki" (finished 720), Japan was founded in 660 BC by Emperor Jimmu, who was said to be a direct descendant of the sun-goddess Amaterasu. The current Emperor is Akihito. He acceded to the Chrysanthemum Throne upon the death of his father, Emperor Shōwa (Hirohito), in 1989. The Japanese government announced in December 2017 that Akihito will abdicate on 30 April 2019.
Article 96 of the Japanese Constitution
Shinzo Abe, the current Prime Minister of Japan, has been a vocal proponent of revising Article 96, stating that "It's unfair that just more than one-third of lawmakers could block revisions even if 50 percent or more of the public want to amend the Constitution". Given that his Liberal Democratic Party controls both Houses of the National Diet (for the first time in nearly a decade), political pundits say that he has a fair chance to succeed. However, the Liberal Democratic Party's coalition partner, New Komeito, may be unwilling to support such a change, and in fact, the Liberal Democratic Party appeared to drop the issue from its platform in the run up to the House of Councillors election in 2013. Moreover, the Japanese population appears to be roughly divided regarding the revision of Article 96, with 42% in favor and 46% against according to a recent Mainichi Shimbun poll. A separate NHK survey showed that nearly 50% of Japanese had no opinion on the subject.
