Trump once gave the emperor a viola because Mr. Naruhito loves music and gave Chinese President Xi Jinping a set of pots.
It is customary for world leaders to give gifts to their peers when they visit.

When visiting the UK in 2019, Trump presented the Queen with a silk and silver brooch worth more than $ 4,000.
Trump and Melania donated a limited edition set of books "The Exploration of Lewis and Clark", estimated to be worth $ 2,700, to then-British Prime Minister Theresa May.
The Trump administration also pays attention to local traditions and culture when choosing a gift for Chinese President Xi Jinping for a set of $ 2,900 pots.
Noting the athletic love of former Japanese Prime Minister Shinzo Abe, Trump presented him with a boxing glove signed by Million Dollar Baby director Clint Eastwood worth about $ 2,000.
Trump also offered Abe a break at the Mar-a-Lago club, a move that sparked public ethics controversy, even though Trump claims he paid for it himself.
Emperor Naruhito was talented at playing the viola and performed in a university symphony orchestra.
Hungarian Prime Minister Viktor Orbán was given the shirt of the D.C. team

Trump does not have to think too much when choosing gifts for Pakistan Prime Minister Imran Khan, a former cricketer.
Trump has also received expensive gifts.
Prince Abu Dhabi presents Mr. Trump with a bronze statue of three antelopes USD 3,700, the King of Kuwait donates a set of gold-plated coins for $ 1,600, and the deputy prime minister of Oman presents a bottle of royal perfume in a cowhide suitcase.
Trump has also received fine pens and paper from German Chancellor Angela Merkel worth more than $ 5,200, a map of the United States from French President Emmanuel Macron worth $ 1,100 and a lion statue in a sandstone crown.
However, US federal law prohibits government employees, including the president, from accepting gifts worth more than $ 390 from abroad.
If not purchased, they are considered state property and many of the gifts are collected in collections in the presidential museum and library.
