FILE - Japan's Emperor Naruhito is shown around The Quire in St George's Chapel, Windsor Castle by Charlotte Manley, St George's Chapel Chapter Clerk, as he continues his state visit to the UK, in Windsor, England, Thursday June 27, 2024. Naruhito and the Empress Masako, who studied at Oxford a few years after her husband, wrapped up a weeklong trip to Britain on Friday. Their itinerary combined the glitter and ceremony of a state visit with four days of less formal events that gave the royal couple an opportunity to revisit their personal connections to Britain.
