光格天皇
On 13 July 2016, national broadcaster NHK reported that the Emperor intended to abdicate in favour of his eldest son Crown Prince Naruhito within a few years, citing his age; an abdication within the Imperial Family had not occurred since Emperor Kōkaku abdicated in 1817. However, 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 required an amendment to the Imperial Household Law, which at that time had no provisions for such a move. 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. On 1 December 2017, Prime Minister Shinzo Abe announced that Emperor Akihito would step down on 30 April 2019. The announcement came after a meeting of the Imperial Household Council.
