Prince William escorted the Emperor and Empress from their overnight hotel in London, arriving almost 10 minutes late in chauffeur-driven cars.
His wife, Princess Kate, returned briefly to the spotlight at Trooping the Colour on June 15 despite her cancer treatment.
However, she is not expected to take part in the visit this week.
At the end of the welcome ceremony today, there was a traditional carriage procession to Buckingham Palace where a private lunch was held.

The two Heads of State sat together in the lead coach, followed by Camilla and the Empress who has a chronic allergy to horse hair.
Therefore, Masako wore a white face mask as a precaution.
Missing from the State Visit is Princess Anne, who remains in hospital today after suffering minor head injuries and concussion.
A horse reportedly kicked the Princess Royal on her Gatcombe Park estate in Gloucestershire on Sunday.
