Japan's Emperor Naruhito visited one of Britain's most important medical research centers on Wednesday, as the second day of a state visit highlighted the scientific and cultural links between the countries.

The 64-year-old emperor and his wife, Empress Masako, were welcomed to London by King Charles III and his wife, Queen Camilla, on Tuesday with a gun salute, military parade and carriage ride to Buckingham Palace before a state banquet.

In his speech at that event, Charles, 75, who was diagnosed with cancer earlier this year, spoke of how Britain and Japan shared the spirit of collaboration and innovation, making the Francis Crick Institute biomedical research center a fitting place to visit.
