Emperor Naruhito and Empress Masako returned home on Saturday after a seven-day trip down memory lane that saw them visit the medieval university city of Oxford, where they both studied in the 1980s, on the final day of their trip.
The imperial couple's formal state visit concluded on Thursday with a goodbye from King Charles and Queen Camilla at Buckingham Palace, but they squeezed in a trip to Oxford before flying home.
The 64-year-old emperor attended Oxford's Merton College in 1983-1986, while his wife, Empress Masako, 60, studied international relations in the late 1980s down the road at Balliol College.
