Naruhito, Crown Prince of Japan

Naruhito became the new emperor of Japan at midnight on Wednesday, taking on the world's oldest monarchy after the historic abdication of his father, Akihito.

Japan also begins the new imperial era of Reeva or "beautiful harmony" that will last, while Naruhito, 59, today, remains on the throne.

Japanese Emperor Naruhito formally took up his post on May 1 a day after the abdication of his father, saying he felt a "sense of solemnity" but pledging to work as a symbol of the nation and the unity of its people.

Emperor Akihito of Japan formally stepped down on April 30, the first abdication for 200 years in the world's oldest monarchy, as his son Naruhito prepared to take the Chrysanthemum Throne and usher in a new imperial era.

Japan's lower house of parliament passed a bill on June 2 that allows ageing Emperor Akihito to step down, as it also called for a rare debate on the role of women in the male-dominated monarchy.

Britain's Prince William compared royal notes with Japan's imperial family on Febç 27 in the tradition-laden Imperial Palace that dominates central Tokyo.
      
The young scion of the House of Windsor was welcomed by Emperor Akihito and Empress Michiko at the entrance of the imposing palace, which is cut off from the hustle and bustle of Tokyo by a large moat.
