Emperor Akihito and Empress Michiko escorted Sweden's King Carl XVI Gustaf and Queen Silvia to a preview of a special exhibition in Tokyo marking the 150th anniversary of diplomatic relations between the two countries on April 23.

"The Art of Natural Science in Sweden--Treasures from Uppsala University” will open to the public at the JP Tower Museum Intermediatheque in the city’s Marunouchi district on April 24 and will run until Aug. 26.

The exhibition introduces audiences to the pioneering work of 17th and 18th century scientists Olaus Rudbeck, Carl Linnaeus and Carl Peter Thunberg.

Princess Mako, the eldest daughter of Prince Fumihito and Princess Kiko, works at the museum and was on hand to welcome the visitors.

Akihito, who is known for his studies of goby fish, visited Sweden in May 2007 for celebrations marking the 300th anniversary of Linnaeus' birth. He also went to Britain to give a keynote lecture in English at the Linnean Society of London titled “Linnaeus and taxonomy in Japan.”

The Swedish royal couple were to attend a dinner at the Imperial Palace in the evening.
