Emperor Akihito is determined to perform all of his official duties until his abdication a year from now, rejecting the Imperial Household Agency’s request that he slow down, his aides said.

Among those duties, the 84-year-old emperor plans to visit Fukushima and three other prefectures before he abdicates the throne on April 30, 2019. His son, Crown Prince Naruhito, 58, will become the new emperor the following day.

Imperial Household Agency officials planned to delegate some of Akihito’s official duties, excluding those designated under the Constitution, to Naruhito or Prince Fumihito, the emperor’s younger son.

The plan was meant not only to ease the emperor’s burden in the final year of his official capacity but also to help Naruhito’s staff become accustomed to their new roles starting next year.

In recent years, Akihito has shown signs of declining strength during his official trips.

But officials said Akihito did not agree to the agency’s proposal that he slow down.

“With limited time left before his abdication, the emperor is set to fully perform each one of his official duties,” a senior agency official said.

Akihito expects to visit Fukushima Prefecture, which is still struggling to rebuild after being hit by the Great East Japan Earthquake, tsunami and triple meltdown at the Fukushima No. 1 nuclear power plant in 2011, as well as Rishirito island in Hokkaido.

Other possible destinations are Hiroshima and Nagasaki.

As he has done in the past, the emperor also plans to attend a memorial ceremony for Japan’s war dead on Aug. 15.

Akihito intends to pull out of all public functions after he abdicates, in part to avoid a duality of imperial authority, with him on one side and Naruhito as the new emperor on the other.

Akihito will be the first emperor to abdicate in about 200 years. His abdication was authorized by a special measures law passed in June 2017.
