Emperor Naruhito, Empress Masako and their daughter, Princess Aiko, offered prayers Friday for the victims of the U.S. atomic bombing of the city of Nagasaki in the closing days of World War II.

Led by Nagasaki Mayor Shiro Suzuki, the family visited Nagasaki Peace Park. They offered white flowers and bowed deeply at a monument marking the epicenter of the Aug. 9, 1945, atomic bombing.

The family arrived at Nagasaki Airport on a special flight from Tokyo's Haneda Airport earlier Friday. It is Princess Aiko's first visit to the prefecture and the first for the imperial couple since the emperor's ascension to the throne in May 2019.
