Leaders around the world have offered congratulations to Emperor Naruhito, who ascended to the Chrysanthemum Throne on Wednesday a day after his father, Emperor Emeritus Akihito, abdicated.
U.S. President Donald Trump and first lady Melania Trump sent their "profound congratulations."
"We will renew the strong bonds of friendship between our two countries," Trump said in a statement that referred to Japan's new imperial era of Reiwa, which the accession ushered in.
