Britain's King Charles and Queen Camilla welcomed Japan's Emperor Naruhito and his wife to London on Tuesday (June 25), marking the start of a three-day state visit which includes a military parade, carriage procession and state banquet.
Charles' son and heir to the throne Prince William had earlier travelled to the hotel where the 64-year-old emperor and Empress Masako were staying, before the trio arrived for a ceremonial welcome at Horse Guards Parade on Tuesday.
The emperor's trip seeks to celebrate and deepen the military, cultural and scientific ties between the two countries, and was postponed from 2020 due to the pandemic.
