2019 Japanese imperial transition
Emperor Akihito of Japan is set to abdicate on 30 April 2019, which will make him the first Japanese Emperor to do so in over two centuries. This marks the end of the Heisei period, and will precipitate numerous festivities leading up to the accession of his successor, Crown Prince Naruhito. The enthronement ceremony will likely happen on 22 October 2019. Akihito's younger son, Prince Fumihito, is expected to become his brother's heir presumptive.
The Emperor and the ConstitutionEdit
Senior officials within the Imperial Household Agency denied that there was any official plan for the monarch to abdicate. A potential abdication by the Emperor would require an amendment to the Imperial Household Law, which has no provisions for such a move.
Speech to the nationEdit
On 8 August 2016, the Emperor gave a rare televised address, where he emphasized his advanced age and declining health; this address was interpreted as an implication of his intention to abdicate.
In October 2016, the Cabinet Office appointed a panel of experts to debate the Emperor's abdication, which recommended that the law should be a one-off measure for Akihito alone.
In January 2017, the Lower House Budget committee began informally debating the constitutional nature of the abdication.
On 19 May 2017, the bill that would allow Akihito to abdicate was issued by the Japanese government's cabinet. On 8 June 2017, the National Diet passed a one-off bill allowing Akihito to abdicate, and for the government to begin arranging the process of handing over the position to Crown Prince Naruhito. The abdication has been set to occur on 30 April 2019.
Imperial Household CouncilEdit
The Imperial Household Council has 10 members including the Prime Minister Shinzō Abe, Speakers/Presidents of the House of Councillors and House of Representatives of the National Diet, the Chief Justice of the Supreme Court, the Grand Steward of the Imperial Household Agency, and two Imperial Family members. Of the latter, Prince Akishino, the Emperor's younger son, has been asked to stand down, as he is an "interested party" in the matter. He was replaced by Prince Hitachi, the Emperor's 82-year-old younger brother, the other one is Hitachi's wife Princess Hanako.
Chief Cabinet Secretary Yoshihide Suga told reporters that the date was chosen to permit the old Emperor to be able to preside over a 30th anniversary Jubilee and to coincide with the Golden Week annual holiday period, turning the changeover from a period of mourning and makeshift ceremonial into a joyous, well-planned, festival.
Finally, on December 8, 2017, the government created a special committee to oversee the events. According to Chief Cabinet Secretary Yoshihide Suga: "It will deal with the matter properly, taking into consideration the possible impact on the people's lives.”
Preparations for the imperial transition 2017–2019Edit
The committee met for the first time in January 2018, and the following month announced that a plan called a "basic policy statement," was released on April 3. Official farewell celebrations will begin with a 30th Jubilee ceremony on February 12, 2019, a delay which would avoid any implication of a celebration of the death of Emperor Shōwa on January 7th.
Golden Week, 2019Edit
The government has consolidated the Golden week holidays into a special ten day block lasting from April 27 to May 6. Had the transition not been scheduled in advance, April 29 and May 3–6 are already national holidays in 2019, following the weekend of April 27–28. The abdication and enthronement would both be National holidays, and public law states that a regular work day sandwiched between two national holidays would become "Public" holidays.
Since the Meiji Restoration in 1867, a new Japanese Era starts the day after the old Emperor dies. However, in Emperor Akihito's case, manufacturers of calendars, forms and other paper products will need to know the new Era's name in advance to produce their wares in a timely manner.
While the Era names for the Shōwa and Heisei eras were kept state secrets until the deaths of the old emperors, that will not be possible in this case, because the abdication is unprecedented since the first constitution was adopted. In order to prevent divisive debate on the subject, delaying the announcement as late as is practically possible, either the old emperor's birthday or his jubilee celebrations have been suggested.
Until the Era name becomes known, computers and software manufacturers will need to test their systems before the transition in order to ensure that the new era will be handled correctly by their software. Some systems provide test mechanisms to simulate a new era ahead of time.
