He is a UK waterways enthusiast and he and his wife have already visited the Thames Barrier as part of this trip which has come close to the General Election on July 4.
The tour is set to end a week before voters head to polling stations - something that never happened during the late Queen Elizabeth II's 70-year reign.
As covered in the River Thames Society's Thames Guardian magazine, the Japanese Emperor studied at Merton College from 1983 to 1985 and wrote a thesis on cargo-carrying on the Thames in the 18th century.
He also published a memoir entitled The Thames and I - A Memoir by Prince Naruhito of Two Years at Oxford.
The book was translated by Sir Hugh Cortazzi and told of the then Prince Naruhito's experience as the first person in direct succession to the throne to study outside Japan.
The book explores his daily life and first-time experiences - including his discovery of beer and being banned from a disco because he was wearing jeans.
Empress Masako also has a connection to Oxford having studied international relations at Balliol College.
On Tuesday the Prince of Wales will greet the royal couple at Horse Guards Parade, before a state carriage journey to Buckingham Palace for a ceremonial welcome by the King and Queen, a visit to Westminster Abbey and an evening state banquet at Buckingham Palace.
