Japan's Crown Prince Naruhito, (L) and Crown Princess Masako visit a photo exhibition to celebrate the 50th wedding anniversary and the 20th anniversary of the coronation of Japan's Emperor Akihito and Empress Michiko at a department store in Tokyo on April 16, 2009. In the half century since they married, Japan has emerged from the aftermath of World War II and US occupation to become Asia's economic powerhouse, and the Chrysanthemum Throne has changed along with the times.
