Debate over Emperor Akihito’s evacuation to Kyoto in days after Fukushima nuclear disaster
- Former Emperor Akihito stepped down from the throne on April 30, 2019, becoming the first Japanese monarch to abdicate in around 200 years
- On March 11, 2011, the Fukushima plant was flooded by tsunami waves exceeding 10 metres triggered by a magnitude 9.0 quake

The government led by the now-defunct Democratic Party of Japan unofficially proposed that then Emperor Akihito evacuate to Kyoto or somewhere further in the west from Tokyo immediately after the start of the Fukushima nuclear disaster in March 2011, a former administration official has said.
However, the Imperial Household Agency flatly dismissed the idea, saying there was “no way” the emperor would do it at a time when people were not evacuating from Tokyo, leading to the government of Prime Minister Naoto Kan to give up the proposal.
Several former senior officials at the prime minister’s office separately said the DPJ administration at the time also briefly considered evacuating Prince Hisahito, the son of Crown Prince Fumihito and Crown Princess Kiko, from Tokyo to Kyoto.
Prince Hisahito became second in line to the throne when his uncle, Emperor Naruhito, ascended the Chrysanthemum Throne in May 2019. The prince was four years old when the Fukushima Daiichi nuclear plant suffered core meltdowns following a devastating earthquake and tsunami in northeastern Japan.
Former Emperor Akihito stepped down from the throne on April 30, 2019, becoming the first Japanese monarch to abdicate in around 200 years, his eldest son succeeding him the following day.
